WiFI with S3 unreliable - Galaxy S III Q&A, Help & Troubleshooting

Hi There!
I have two Zyxel WAP-3205 access points in my house. One is set up as an Access Point, the other as a repeater using the wizard.
I have found the S3 (in fact most Samsung mobile devices including GT's) doesn't seem to "hand off" between the access points properly making for miserable performance. It seems a little better if I turn off the wifi and then turn it back on again.
Also is the N on the S3 single or dual stream?

It may be unrelated but I have a Zyxel router too and although my connection on my SGS3 is okay(ish) now (I get dropped connection sometimes on > 500mb file dls) on my previous SGS2 the signal would drop 4/5 times a day. Changing wifi settings had no impact but I was told by a techie that you can upgrade your router software if you phone Zyxel.
Good luck.

Wifi AP switching like iOS devices, possible on andriod?

Is there a method or an app that can automatically handle wifi switching between access points based on signal stregth.. like how an iOS device natively jumps to another AP if the signal strength is pretty low on the currently connected one.

I would love this to happen, I have 2 APs in my house & both my Galaxy S2 & EeePad refuse to pick up the best AP when I move about often resulting in my losing the signal.
Surely this is pretty straight forward & would benefit most Android users ?
Anyway, if anyone has an answer or can develop a simple solution I would be interested.
I'm having the same issue. I have 3 floors at my house, with cement between each floor so the wifi signal degrades quite a bit between floors. I have now setup 3 APs at my house (one for each floor) and I have to turn my wifi off and then back on the Galaxy S2 to get it to connect to the strongest AP - really annoying that Android doesn't do wireless AP switching...
Anyone have a solution for this yet?

[Q] bandaid for asus pime wifi

Hello to all, I'm wondering if other is anyway to connect my phone to my home router then broadcast that signal to my prime. So instead of using my data from my 3g I would just be rebroadcasting my home wifi signal. I think this would be a type of band aid until the prime gets some kind of fix for wifi farther than 20ft. I thought of this when I went outside and my prime had no signal but my phone did. I thought it would be nice to piggy back that wifi signal my phone is picking up on. I have a tethering plan on my phone that works fine but when I'm right outside my house I hate to use data when my wifi is simi-free.
Thanks to all for any response.
I've been reading about mifi cards as alternative but then thought " is their anyway to buy a unlocked (I'm assuming their locked to carriers) mifi card and instead of it picking up 3g or 4g date can it be modded to pick up the closest or strongest wifi signal and then use its hotspot ability to transmit it." I'm not sure but I would assume that it would have a pretty good receiver in it, at least better than the prime in its current state.
If these are crazy ideas... I can take it I'm a big boy

What about a bog standard wireless access point or repeater, as that way you do not have to worry about connecting to yer phone?
Not sure if this I correct but is a bog standard router just a better router? Also I think a repeater would probably work I just can't seem to be able to find a battery operated small one (pocket sized). The problem I'm running into is that as a firefighter most of our firehouses are brick and concrete with steel mixed in, not the bet setup for wifi. My phone is able to pick up the wifi from pretty far away even though the signal is poor to fair but my prime is not. So I need something that I can slip into my pocket that will pick up the weak signal and boost or simply give the prime a closer access point. We rove to different stations almost everyday so it needs to be something portable. Hopefully this clears up my situation.
Thank you for your reply.
I think you cant connect and broadcast the wifi signal at the same time with your phone. You either use the antenna and hardware to receive a signal or you use it to broadcast but not both at the same time.
Correct me if i'm wrong though
Well that might kill my cell phone idea.... their has to be something that can be done. Besides just fixing the prime.
I have done what you have said but it does depend on what cellphone you currently own. I have a Samsung Galaxy Captivate with an ICS rom and so my phone is able to transfers a Wifi connection right to my prime using Bluetooth.
Also, seems that when my phone loses WiFi connection and switches to 3g my prime auto disconnects so I don't use up my 3g bandwidth.
That sounds about what I need. You don't know if its only that phone? I have a inspire 4g running ICS from the dhd board. Is it app your using or built into your phone or ICS?
I am using the method that is built into the OS.
On your Phone:
Settings -> More... (under Wireless and Networks) -> Tethering and Portable Hotspot ->Bluetooth tethering.
Connect your prime and phone using Bluetooth.
On your Prime:
Settings -> Bluetooth -> Settings button beside your phone's name -> Internet Access
Then if it works the text "Use for internet Access" will switch to "Connected to devices for Internet"
Bluetooth tethering is super slow, there are some apps were you can tether your wifi connection while connected to another wifi network.
Can't think of the name of the top of my head, maybe someone else knows..
Bluetooth tethering worked with my phone so thank you. It does seem to be a lot slower but this was a bandaid for my prime so at least it works. Slow speed is better than nothing. Cost cutter It would be nice if I could find that app your talking about. Was it on the market?
Is it possible to have multiple bluetooth connections without fracturing thoroughput? I.e. run Tablet Talk at the same time.
You might also try a USB wifi stick if you have the dock or adapter.

[Q] Razr wifi problem

Hi all ,
I met wifi problem with a dozen roms ... i flashed and wipe ... firstly I think is my phone hardware problem , but after I changed the channel of my rounter to channel 1 ... the problem solved...(so far)... I would like to ask if any razr owner have the same problem also ?
Hi mate,
I'm experiencing some WiFi problems with my RAZR and the home Linksys router as well. Haven't tried your solution with Channel 1 yet, though, but I'm gonna go and switch to it right away and report the outcome.
EDIT: Weird... Now my WiFi connection is almost lightning fast and no data losses. Well, thanks, hiha!
Speaking of Linksys routers... a While ago I changed my Linksys WAG120N router from G mode to N mode. Strangely, my RAZR started to reboot randomly. I switched the router back to G, and everything got back to normal.
Funny things are happening, it appears.
My Linksys E4200 is currently in Mixed mode and set on Channel 1 - this appears to be the optimal configuration for work with RAZR.
I also have problems with wifi. Really bad signal at home, like 5 meter away it drops to zero
I tried channel one, still same problem.
I noticed when u hold the phone and cover the right side wifi drops and dies constantly. Just like the iphone 4

I'm on my 2nd Razr Maxx (first one had a cracked screen), and neither has/had any issues with my Wifi network. My router is on the 2nd floor (FiOS Actiontec, mixed mode G N). I get a good signal throughout my entire house, and have never had a single problem.
I hope ics fixs the wifi signal, its horrible. I am now on 2.3.6

wifi issue
My wife has a droid 3 and I have a razr. I am running netgear routers
with dd-wrt open source software. Both of these phones were unusable
when we first tried them. I logged into my router and set the qos settings
to enable and both phones now work flawlessly. It seems that the wifi chip
in these phones cycles on and off to conserve power. Without the proper handshaking between the two devices ,when the phone chip shuts down the
buffer overflows in the router and it disconnects because the data
is no longer valid. By eneabling the quality of service setting the router and
the wifi chip use a protocol to prevent this buffer overfllow.
If you search the microsoft knowledge base you will find that vista and win 7
had to have a software upgrade to address this same problem when they
first came out.
Some modems have the qos disabled by default to maintain a higher
throughput.
If you go to the dd-wrt wiki and search for qos it goes into more detail
as to how this works.
Wifi issues here too.
Forget low connectivity, my phone blatantly refuses to even connect to a connection secured with 802. 1x EAP. It is embarrassing to say the least.
I have issues where mobile connection and wifi go blue to grey after a while and no longer work. Possibly what the op refers to.
Also, similar to the iphone4 problems, holding my phone reduces both wifi and mobile data signals drastically. Is this a general device issue?
I am wondering if its something the motorola ics release might address.

[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!

Have any of you tried this ^ ? Mine is set up like that, and no issues at all. I did have those issues on my Captivate until I did above.
I'm having a rash of the issue tonight--dropping wifi and now says unable to connect due to poor reception (I'm sitting beside my router)...

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.

Interesting. Given that I don't seem to be having any issues, it seems it is not a problem for everyone.
Had the same problem. Net gear router wrnd3400. Wifi kept dropping so then I connected to Verizon router and no problems. Seems to be a problem with some after market routers.

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.

"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
Sent from Rooted Note 3 (stock rom) Xposed framework
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.

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.

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.

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
