Any thoughts on my WiFi problem for AT&T? - Galaxy S III Q&A, (US Carriers)

Alright ill try to make this quick. :laugh:
I got my GS3 last Saturday from AT&T and ever since I have been having issues with the phones WiFi turning off and back on. My parents both got their own S3's and neither of them are having the same issue. I first noticed it when my phone would not unlock until it disconnected then I would have to go in and manually turn WiFi on and off. I have tried to research it the last couple days and found the *#0011# trick (which works for me) but I would rather not feel like I have to have it turned off when others can have it on. I have also seen that, for other carriers, there are other settings that can cause the problem but i do not have these settings.
To add to the problem, I am currently living at college which means I have WiFi nearly everywhere but I do not have access to any settings.What I would like to know is if this is a hardware issue or software issue. I feel it would be software because how else would it work with WiFi power saving turned off? but then again why would it not be the same on all phones? In just torn on what to think about the issue because I would really hate to be stuck with a phone that is having these problems when I could have one that does not.
Thanks!

Are you all connecting to the same access point? I'm starting to wonder if maybe the problem is happening with certain access points configured a certain way and not with others that are configured another way. I have a similar problem in which my wifi sometimes goes into a cycle of constant disconnects and reconnects but it has only happened at work. At home it is fine.

Yes, at least when i was home for the weekend that is. When we compared, mine would consistently disconnect/connect and theirs are always stable. I just dont know what to think anymore because it works flawlessly when "WiFi power saving mode" is turned off and neither of theirs are messed with.

With a bit of searching you'll find a few posts from folks having problems with WiFi. I was one of them.
Yesterday, I exchanged my phone for a new one, and it is working fine.
I'd suggest that you don't let your 30 days run out before trying a swap.

This has been happening to me and today I got a replacement phone from the store. It still happens so I'm positive it's a software issue and will be addressed.

Well...it just makes me wonder what the difference is. You would think it wouldn't be software because all the phones should have the same software. And you wouldn't think it would be hardware because it works when power saving mode is off.
I guess ill go in and talk to some AT&T people this weekend but I don't want to go through the hassle again.

It's a little of both software on the phone and router. The phone is reported to have problems with 'business" class routers. The phone has problems with routers that don't have WMM enabled (a business router might be set this way, and some home routers default to disabled). The phone doesn't like mixed encryption networks (TKIP + AES is the most common, and that won't connect). It doesn't like networks set at 40mHz wide either; I have a N300 which when set to 'upto 300mps' the phone won't connect but up to 145 will. The phone is better with G only than N only, better with Mixed protocol.
Many people have had thier routers for a few years. They don't upgrade the firmware (don't if there's not a issue), however it appears that some 2-3 year old routers also may still be running DRAFT N protocols. Router firmware update is advisable.
The powersavings and change in signal strength from the *#0011# is less than just turning powersavings for the phone off. Combined together is worse than just the powersaving by itself.
Since you can't control most of these factors at school, A) perhaps your parents would swap phones with you so you can see if it's pervasive or B) call either Samsung support or ATT and have them swap the phone and see if that's better.

When you say "The powersavings and change in signal strength from the *#0011# is less than just turning powersavings for the phone off. Combined together is worse than just the powersaving by itself." what do you mean? are you talking about the power saving in the service menu and the one in setting?

I'm sorry, I mistyped.
If you have both turned on, phone and wifi powersave it's not as much as the wifi service powersave itself, which can be 15% (with possible battery usage increase).

After HSDPA drops HSDPA stays disconnected

Hey, so today I was riding the train back from work and its kind of insane on the signal part for the phone because it jumps through thousands of towers and internet is really crappy on my train line. Funny thing is I lost HSDPA signal and when I got off the train to an area I know I have reception in and got home it was still "stuck" with the upload arrow green, and refused to load pages. I turned it on and off (data connection) and it got back to normal. Shouldn't it do that automatically? is that a known bug or do I have a falty device? its brand new and this is the second time it has ever happened to me with it...
yes, it should go back automatically but since it was trying to hop so many towers it may have gotten confused and freezes. just reset it.
If it happens continuously then it maybe a issue but if happens the odd time I would not worry about.
Well it didn't happen until now and I've had the phone for over a week. Talked to a rep and she "refreshed" my connection and connected me to a different APN. I have also disabled "fast dormancy" (FD) which is an option that causes the phone to "pause" connections when nothing uses them which is only available on GS2 and some carriers don't support. My carrier doesn't. My thought is that this causes the device to keep its data connection dormant after trying to awake it. The upload arrow stays on implying that the phone is waiting for a response from the network which doesnt happen since it doesnt support FD which causes the connection to freeze. Reseting the connection fixes this. In any case, I've read in this thread http://forum.xda-developers.com/showthread.php?t=1132399 that the problem is solved by doing these two actions - changing APNs and disabling FD. If anyone else has an insight on this I'd love to hear it. I'll report here with tommorow's upcome.

[Q] Wi-Fi issue hardware or software?

Recently picked up a gs3 and I like it but one thing that is really bothering me is I'm getting constant drop outs on wi-fi and the reception is very low unless I'm standing next to the router.
Other devices do not have any issue at all. I've also noticed when scanning wifi the gs3 doesn't pick up as many routers as other devices do.
I've been reading threads and noticed a member mention going into the service menu and disabling power saving on wi-fi but that has not solved the issue.
I'm wondering whether it's a hardware or software problem. If it was software then surely others would have issues?
I don't really want to exchange the phone incase I get screen issues like the pink tint or blobs people are having.
But obviously if I have a hardware fault then I'll have to get it exchanged as a phone that keeps disconnecting from the wifi is not useful to me.
I also have this problem but it also extends to my 3G connection. Does not connect until I restart my phone, doesn't happen often, but its a pain when it does. I downloaded a WiFi fix from Google play and so far so good not had any problems...this is the only problem I have with this device otherwise its a beast of a phone.
Not sure if your setup is like mine but i had two routers in my home broadcasting the same ssid and channel. I kept facing frequent dropouts until i changed the channel on one of them. It seems the device kept bouncing between the two routers even though i was much closer to one. No more drops once they both broadcast on different channels
i read somewhere in this forum that you have to change the setting of the band of the router to 5ghz.
that fixed the connection dropout of wifi.

I only have one router. But I will try changing channels as maybe there's a lot of congestion on the channel I'm using.

I've read about that on here but I don't think my router has that option.
I'll go into the config and see if it does.
Thanks for all the replies
Just to update the thread, since I started this thread my wifi has been awful the way it keeps disconnecting especially when downloading large files.
I've been googling and had tried lots of different things.
What finally seems to have solved the drop out issue is turning security on my router to wpa instead of wpa2.
No drop outs so far even when downloading large files, but the signal strength is really bad, not sure if I still have a hardware fault or whether the galaxy s3 wifi is just weak.
Hi,
Same problem with mine. weak signal. At home or at work.
I think this an issue (hardware ? software ?).
But I'am surprised that we are alone.
Me too
Same issue here with regular random wifi dropouts at 2 ap's. Radio streams far more reliably over 3g!

i found this thread on xda, i'm hoping it does the trick
If you are using 2 APs with the same SSID and settings, your device can roam seamlessly only if the underlying network is the same network. If the 2 APs connect to different network subnet, it will never be seamless and you will get connection drops.
Your device must receive the same IP and subnet from the same DHCP with same gateway so it will be seamless between 2 APs.
I had issues at work. But not at home.
Today I told it to forget my B/G radio and to connect to the N radio. No disconnects, none..
No changes made to the phone at all..
May not be router
Hi, for what it's worth, my husband and I each have an s3. Mine has no problems at all with wifi anywhere. His drops out at home. I posted more here: http://forum.xda-developers.com/showthread.php?p=28510251#post28510251
We've tried the *#0011# trick and that is a temporary fix, but we need to redo it on a regular basis. The setting is not saving.

[Almost SOLVED] WiFi connect/disconnect

Update, I've had my phone replaced by Samsung tech in Plano TX, that doesn't help, but updating my router to the Apr 2012 eko dd-wrt did make some differences. Also the ota update from att has a new modem apk and that also chg'd the phone functionality. One thing that I have seen is that the phone reports the wifi network signal as being lower than before, and the output signal is slightly higher. I find that I have to occasionally turn the wifi on and off to reset it.
Short list of fixes and things to try:
1 update routers firmware
2 no dual encryption
3 some routers with 300 or greater Mbps settings need to be toned down to 150 or less
4 phone likes mixed protocol network over N only.
5 turn off phone power save
6 un check the carrier hot spot notify.
7 un check open wifi notify
8 pick a single band 2.4 or 5ghz. Note that updates with this can temporarily lock in to that frequency and not allow changes.
9. Dial *#0011# menu button, wifi and turn off the power save setting. This has to be done on every boot, and may cancel the display timeout.
10 On 5Ghz don't use DFS channels
Incorrect since people who have installed some roms and cm 10 are saying that they don't have any problems: I am almost certain now, that the wifi disconnect/connect issue is hardware incompatibility.
I have Linksys wrt-610 v2 -- which has problems
I have Netgear WHR3500L which has problems
I have Linksys wrt-54GL v1.1 which has NO problems (had to dig this out of storage)
If YOURS works or YOURS doesn't work pls visit this thread and post your info so we can find out what routers do and don't: http://forum.xda-developers.com/show....php?t=1752356

I've posted this and then the mod's moved the thread http://forum.xda-developers.com/showthread.php?t=1722363&goto=newpost to the Sprint version of the forum.
Here's a recap since the guy has a sprint phone and won't recognize my issue there.
Here's the issue I've been having. I'm in a very active 2.4 wifi neighborhood. Even though I had the advanced wifi set to 'Always on' it kept disconnecting (and instantly reconnecting) to my network. The phone is scanning the neighborhood almost every 15 seconds. It's simply WPA-2 with just AES (and I'm not changing to TKIP)
This is a problem for me as I use "Unlock wtih WiFi" to keep from having to enter my PIN when I'm at work/home and "Home Sweet Home" which uploads any photos I have taken to my server when it detects the home wifi network (and deletes them from my phone after 3 months).
Anyway, I was just on the chat with Samsung and in the end we did this,
1. disable the ATT WIFI auto login function (seems there's something similar on the Sprint phones that's a issue).
2. soft reboot the phone (turn off, pull battery, count to 30, boot up)
However this suggested solution doesn't work.
The wifi isn't staying connected though the breaks are very very temporary, but long enough for those apps to kick in.
Update additional things tried:
3. Turned off WiFi power save in the *#0011# service menu
4. Turned off Open WiFi notifications, ATT Autologon.
5. Selected a single wifi band (5Ghz) where there is ONLY one network, mine
FWIW, I like that it connects to my 5Ghz wifi at 150 mbps, the speed is great.
6. I've disabled the Unlock with WiFi and it still occurred.
Here's a video of the issue showing the phone:
http://youtu.be/FBo3NFdcMhs
Here's a videoe of the issue showing the router: http://youtu.be/rRALDc8LZOk
and for those technically inclined here's a dump of the logs which clearly shows the drop and reconnect: https://dl.dropbox.com/u/38266113/SendLog.txt
FWIW. I just got off a 45 minute call with Samsung Help Support, went to level 3 support in Texas. This is newly documented, I've referenced this forum for additional reports of the dual encryption and the wifi connnect/reconnect issue I'm having. My ticket # 2113584507 (just for disconnect/reconnect) which you can mention at level 1 as having the same disconnect/connect issue. I specifically asked if I could post the ticket # so anyone could reference it at Level 1, but they will still take your own experience down.
Level 3 said they expect that they will be getting calls today since it's the first full day after the release. So if you want it fixed, CALL SAMSUNG, they're collecting bug reports.
I was having this same problem yesterday afternoon at work. Last night I set my radio to 5GHz only and today it hasn't happened once.
I am so glad I found this as it was driving me nuts on my new Sprint SIII. I think it's bouncing back and forth when both are available as at work, it stayed solid where we only have 2.4.
Thanks!!!!!!
I had that problem the entire time I had my Captivate. Very short disconnects. Only reason I knew was because of a task I was using in Tasker having problems, and I set a method to track connection.
I fixed the problem with setting a static IP address. I used WiFi Static.
I'm using it on the S3 just to be sure.
Had the same problem. However I set it to connect to 2.4ghz and it stopped doing that. If I put it on auto it will do it. If I leave at 5 it won't connect.
I do however think I might have a wifi dead spot. I notice if I hold it a certain way I lose a signal or two on wifi. Or the speed of wifi decreases. Anyone else having the same issue? It might just be me

I've experienced the same wifi drop issues so glad it is being investigated. Thanks to OP for diligence in tracking this down!

although I've gone to level 3, I need you and everyone else experiencing this to report it so that its corrected. Granted they are certainly going to visit the wifi code for the dual encryption issue and stability with Auto frequency, but fixing this could be done at the same time.
FWIW, since I have two routers and 3 networks, one of them is simply a pure G up to 54mbps default firmware setup (since it's the FCC's) and connecting to that greatly reduces but not entirely eliminates the problem (even in the same room). It's much worse on my "N" only networks. And I have tried static IP that also doesn't fix the problem. This is some sort of software issue in the renegotiable speed setting or timing settings or power savings. Off course it certainly could be some badly (or purposely) behaved app software too.

More likely to be a timing issue or protocol issues as the phone scans and tests various networks on different bands and protocols. Many people have n routers that do mixed networks, b, g and n, and they just may not know what they are doing all the time as the phone renegotiates with the router. I have a wrt 610v2 doing only n on 2.4/5ghz and on the the Netgear N300 it drops less doing 2.4 g and at my friends who have a wrt54g and it dropped even less often. The app that I use to enable my lock screen pin makes this more noticeable.

FWIW, I decided to followup on the ticket. Samsung level 1 (not that it matters) says they have never heard of this problem. Level 2 was better, and we in essence setup a new ticket with the videos already linked to it. I offered a sendlog, I offered to install a test app if they have one. I already beta test for a number of app developers as well as some major hardware OEMs.
PLEASE, everyone, call samsung support directly and register a ticket that this is a problem so that they have the information first hand and not via ATT or Sprint, etc which they might ignore.

I just called. They said they would note it 'on my account'. They indicated it would be a Google issue, not Samsung. They only do the hardware (and of course, it can't be a hardware issue, can it? )
I was thumbing through the phone logs from a boot to connection and reconnect. I have to say Chrome has a lot of errors thrown particularly in the bookmark sync. Also it appears that every time the wifi is initially started it checks for authentication for tethering on both the wifi and BT. It almost looks like the phone thinks that the wifi ap is off and restarts wifi scanning.

I have experienced the slow network and disconnect/reconnect issue on this phone since it arrived, but all is normal on our 5 or so other mobile devices with this Netgear WNDR3700 router on the 2.4GHz and 5GHz bands.

[Q] Time to replace the phone a third time?

I got the EVO 4G LTE last friday and, while it worked great, I had it for about 2 days before I noticed that there was something under the screen. I returned it and got a new phone, but unfortunately the new phone had the Wifi / 3G connectivity issue that seems to be happening on some of these phones where both will cut out randomly and while the 3G is connected, it will often get speeds as low as 20kbit/s. So I took that one back also for a third new phone in 7 days, but unfortunately, this new one also has the exact same connectivity issues. I'm wondering if it really is the phone and I should return it again, or if its something else going on. As it stands, my 3G is next to useless in most parts of Denver where I live and my Wifi is only good if I don't need to use it for more than about 10 mins at a time. I should also point out that I don't think its my wireless router since my old phone is on wifi at the same time and it never waivers.
Thoughts?
Thanks

I'll give it a try, but I'm not sure I have the same problem, as it seems like the people with this problem experience almost no wifi connectivity at all due to the signal bouncing up and down. Mine just seems to disconnect once in while for a moment and then reconnect, but long enough to disconnect me from whatever I was using the net for (pandora, various games, store downloads). I hope this fixes it though, since I'm getting sick of replacing phones so often.
Well, this took all of 15 minutes to not work for me. Even with the wifi set to only 2.4GHz, it still disconnected. I guess I'm going to have to replace the phone again.
Have you tried power cycling the WIFI router? I had this problem before, but it seem to stop after I removed the power cord for about 1minute. Also, have you tried a different channel on the router. Depending on how close your neighbors are, you maybe getting interference from a nearby router.
I got mine on may 24th @ BB. Never had any issue other than a few lag moments. I run 5ghz and 2.4. Phone on 5ghz and 3g auto switch and NFC on and no issue. Still get over like 20+ hours moderate use.

My first phone worked great, but had the screen issue. Since then, its just been one bad phone after another... I'm on #5 now (#4 never even touched my hands as the salesperson noticed the same screen defect as my first while installing the screen protecter), and I've got a whole new problem where the upstream connection is much slower than the downstream and ends up getting stuck, with the only way to get it moving again being to turn off the 3G and then back on again.

Depending on your router configuration it might drop your phone from the LAN.
Instead of using DHCP from the router, set a static IP through the phone. There's a guide here. But to sum up:
First, go to Settings > Wifi and tell your phone to disconnect from your network if you're already connected to it.
Select your network once again from the list, and enter your password as usual.
Tick "Show advanced options" and some extra options will appear. Select "IP settings" and choose "Static" instead of "DHCP."
IP Address: The IP address you want to assign to your phone. This should normally be taken from the pool of IPs available for devices to claim via DHCP (check your router's admin page if in doubt). Usually something on the same subnet as your router will do. For example, if your router is 192.168.0.1, then 192.168.0.2 to 192.168.0.254 should be good.
Gateway: The IP address of your router, usually 192.168.0.1, 192.168.1.1 or 192.168.1.254.
Network prefix length: This is a different way of specifying your network's subnet mask (check a conversion table here). For most, the default "24" will work just fine.
DNS1/DNS2: Your ISP's primary and secondary DNS servers. If you're not sure, you can always use Google's public DNS service by entering 8.8.8.8 and 8.8.4.4, as we've done in our screenshots above.

Whenever there is a Wi-Fi problem, you HAVE to try it on multiple access points because the issue might as likely be on your router's end.
As for the 3G, that might just be the area where you're at. It happens a lot more if they're doing maintenance on the towers. I have no insight on 3G, unfortunately.

Depending on your router configuration it might drop your phone from the LAN.
Instead of using DHCP from the router, set a static IP through the phone. There's a guide here. But to sum up:

The same behavior occurred on 3 different routers (home, starbucks, and school). Luckily enough, the newest phone seems to be working ok after 3 hard resets, so I've got my fingers crossed that it stays fixed...

"Internet connection is unstable" issue

OK, I've seen a lot of posts in various forums about this issue, but have yet to find a single thread that captures all the details about what I've experienced. Let me know if I should move this conversation into a different thread.
On my home wifi network, I am able to connect, but constantly receive the error "internet connection is unstable", and I cannot pull any data over wifi. I noticed this issue on my home network after returning from a business trip this week. I'd previously seen the issue occasionally in hotels, etc, and had already disabled the "Passpoint" and "Auto network switch settings". That seemed to work on the road, but now that I'm at home, I'm unable to pull any data over wifi.
My home router is a TP-Link Archer C7, running the latest firmware.
Per Verizon and Samsung's advice, I cleared the cache partition, "forgot" and reconnected to the network, tried using safe mode, and tried a factory reset of the phone. I also restarted the router and changed the router's broadcast channels.
Last night, I rooted the phone via Kingo and installed the Jelly 'Beans' rom using SafeStrap, since I wasn't getting satisfactory answers from support. To my surprise, the issue also occurred on the new rom. I'm not an Android expert, but it seems like this means its either:
1) a hardware issue, or
2) a lower-level software issue (radio firmware? not sure how that works)
I removed root and safestrap, to continue support options with Verizon, but I wanted to ping the community here for suggestions. The timing is confusing to me. I'm pretty sure, though not certain, that I've used my home network successfully since the 12/17 OTA update. However, since so many others are seeing issues, it seems unlikely that this is a hardware issue.
Could others describe their issues and router, so we can look for patterns? Let me know if I should move this into a different thread.
Thanks!
Mine does the same thing from time to time but only on certain roms

yeah, I'd seen intermittent issues previously, but all of a sudden it stopped working at home entirely. Still connects to some other networks, although not all.
After seeing a bunch of posts on the Verizon forums (and just the general timing and behavior of the issue) it seemed like a software problem.
Verizon is actually cooperating, so I may just end up replacing this phone. Wondering if anyone else has seen wifi completely break like this.
This is the only thing I can not stand about my note
I have a Zyxel WAP3205 WIFI access point (Wireless G) that I use at both work and at home.
At home, I have Comcast Business Cable internet, and have absolutely no issues connecting to it. The WAP is connected to a Belkin N600 router, which is then connected to my cable modem (not sure of the model, shouldn't matter TBQH).
At work on the other hand, I have constant connection issues. Albeit, I don't get the 'connection is unstable' notification, but I get constant connect/disconnect problems. I also have almost no (most of the time I can't even send/receive text messages at my desk.....) phone signal (ie not even 1X). I'm not sure if that plays into it at all either. The company I work for uses Windstream for their ISP, and it's complete crap to be perfectly honest. Needless to say, it doesn't change the fact that I'm connecting to the internet through the same device (well, same model/firmware/etc...), and I'm having issues at 1 place and not at the other.
I might also add that my tablet (Nexus 7 2013 running CM11) doesn't seem to have these issues at all and works just fine via the WIFI.
That's about the only information that I can provide. I know my internet where I work is complete crap. I sometimes remote desktop back to my home server to browse the web and download files via that because it's actually faster. I'm not even kidding.
I have 2 routers at home and have experienced the same issue as well and none of my other devices have this problem

Verizon is shipping a replacement phone to me tomorrow, so I'll test this out and see if it makes a difference. I'm on the road until Thursday, so it'll be a few days before I can check on my home router.
The behavior on this issue just seems strange. It began intermittently, but then completely stopped working at my house (but still sometimes works elsewhere). Lots of people report intermittent issues, but a few seem completely broken. Not sure what to make of it, I'm just glad I was able to get a different device out of Verizon. We'll see if that actually fixes the problem.
I haven't had this notification until I got the Note3. Is it possible that its android 4.3? Or this tw 4.3? Anybody know if other folks get this with other devices?

I only have this problem if I connect to the wifi at work, which is odd because I'm about 7 unobstructed feet away from the AP. I don't get this anywhere else.
I had a Note2 on stock rom up to 4.3 and never had the issue. I have a 2012 Nexus 7 latest version, again, no problem. It's only on my Note3 with stock rom that this happens.

It happens on custom roms too.
I've asked a couple devs if they could remove it and they said it been like that in android for along time.But I never experienced it until my Note 3

Same here. Never happened on my Note2 but happens all the time on my Note3. I have two Linksys Routers at home for full house coverage and I can be in the next room and get that message. Just got it earlier. Same routers as I had with the N2 a few months ago. My Tablet, nor the Spouses HTC One Max have that issue and are connecting just fine, and stay connected.
I get this all the time. Got it on stock as well. Only really happens with my ghetto satellite Internet though lol

Has anyone with this issue installed AdBlock and/or an ad-blocking HOSTS file? I didn't start seeing this problem until I did both.
Whenever I see this message I can go into the speedtest.net app and pull a continuous 60mbits down, pretty much maxing my connection, and I never see any actual stability issues.
I think the system may have some connectivity test that's being interfered with but I haven't had time to go digging through the logs yet, so I wanted to see if anyone else had done what I did to trigger it first.
Seems to be two different issues being discussed here without really differentiating the two... the OP states that he is always getting the notification and "can't pull any data over wifi" ... others are saying they are getting the notification without really stating if it is affecting their overall wifi performance at all.
I'm on AT&T DSL... I was getting the notification ALL THE TIME while using the supplied (4 year old) AT&T 2Wire router and it would fail and freeze and disconnect and it was DRIVING ME NUTS... so i went out and got a brand new Netgear N300 router and problem is solved ... mostly
I'm still using the AT&T 2Wire as a modem... disabled it's internal wifi... ethernet cable to the Netgear. .. and BINGO!!! All my connection problems and data problems have gone away... i still get the unstable notification maybe once or twice a week but i figure that's a DSL thing... any little glitches in Internet availability will be detected by the device and displayed so that doesn't bother me at all.
It's almost like this phone does ping tests all the time and if one doesn't come back properly it throws the notification...
i was at a friends house the other day and was getting the notification constantly but was still able to watch YouTube videos and Netflix without much problem... so i did some speed tests on his wifi and his ping and upload were all over the place... His download speed was solid between 20 and 28 but his upload was never even close to normal and failed several times... and his ping was good on some and took forever on others... i also noticed Web pages would sometimes take forever to start loading ... Once they started loading they did so quickly but the start was painfully slow a lot of the time... This would indicate to me that the ping or upload connection has issues or maybe over congested on his iSP.
Anyway... hope this helps others iron things out

When I get the notification, it refuses to use the wifi at all.
I haven't noticed any problems with my WiFi. I host 6 wireless networks, and play with WiFi a lot, War driving, and wireless network setup is a hobby of mine.
One thing I noticed at several throttled Hot Spots My VZW note 3 would test the WiFi speed, if it was slower than 4G it would display a popup, something to the effect "Wireless too slow, using mobile Data" I can't remember the exact popup text. It might be a VZW thing.
I use the OOKLA speedtest, free from the play store. (After you run your OOKLA test, for fun drag the speedometer down to reveal some cool messages about Ookla!
A few wireless router settings I use:
Set 2.4 to N 20 Megs max. N 40 or AC mostly just creates problems with connections, and the neighborhood.
Channels 1, 6, or 11 in USA Use a WiFi analyzer app and pick a less cluttered WiFi channel.
Place wireless router up high away from electronics, construction, and stuffs. Mine is on a pedestal in a window.

Go to WiFi settings/advanced/auto network switch... and turn that off so it won't jump off slow WiFi networks

Thanks,
I just tested "auto network switch" on and then off. It let me connect to one of my throttled networks, without; "Checking quality of internet connection".
I noticed that it only showed; "network disabled because internet connection is slow" on the congested 2.4 GHz band, not with same router on 5.8 GHz.
Radio interference, location, and router settings, can cause many problems on wireless networks.

You're right, I noticed in my research that multiple issues seem to be getting lumped together. I think you're correct in that it's related to the router as well, somehow. I see the notification occasionally on slow hotel connections, but it's intermittent, my problem at home seems permanent. I can use some other wifi networks without problems, though.
That said, I used this phone on my home router for a couple months before ever seeing this problem. I'm guessing it's a combination of the 12/17 OTA update, and particular router models.
Verizon sent me a replacement phone, and it's running the previous build (MJ7 instead of MJE). I'll check things out tonight, and will report back.
Alright, the issue seems resolved on the new phone. This seems to suggest that it is related to the MJE build. So far this phone hasn't asked for an update, but I'm hoping Verizon doesn't break this again for me
