Hi,
got my SGS3 today and started playing with it. I started downloading my apps and during this the wifi dropped connection 3 times. It connected again within seconds, but this is not good.
The distance from my router was around 3 meter. My SGS1 never dropped connection.......
Any idea's?
I also have problems with wifi:
It connects normally but after tens of seconds the connection is dead. Android says still it's connected, but it simply doesn't work.. I have no sim installed atm because I have only an oldskool sim and not a micro sim. Tomorrow I will get a microsim at the vf shop and test again..
I had issues like those aswell today using my Adam but only with wireless. Weird ?
Probably your router problem? I'm sure reviewers would have identified that issue as well. Can't wait to get mine though, hopefully mine don't have the same problem
Htc hero, sgs 2 and three notebooks are working fine. Tried different router configs.. Nothing helped. Today i receive a 2nd sgs 3, so I will put it on the test..

I have a similar issue, the status bar shows wifi is fine (the arrows are blinking) but no actual data on the phone. Checked on my tf201 on the same network and its working fine.
This has happened twice now and only restarting the phone fixes the issue.
I have downloaded over 2 Gb with my SG S3 over Wifi at home and at work. No issues, and it´s super fast, even beating my XOOM.
I have a Dlink 625 at home and at work we have a Cisco something.
However had a different problem where the phone just restarts when dialing a number, and then it boot looped on the logo for about 5 times before starting up. scary .

This is the same problem I was talking about, but rebooting does not work for me..
Mine seemed to behave a little like this to start with also - I changed the Wifi Frequency Band (Settings-WiFi-Advanced) to 2.4ghz only and its been rock solid since.

Yes, it is in b+g+n mixed mode and is saying 2.4ghz. As a matter of fact I'm not able to chose another frequency (maybe because of the b and g). I can try to put it in b/g or g only mode.
I also read about that NFC's RF signals can interrupt the Wifi signal, so I will try also to disable the NFC option.
I tried another galaxy s 3 with the same settings.. that one works well on my wifi network.. I think the wifi module is not working properly..
Do you have by coincidence a draytek router. I have the SGS3, and my sister has the SGS2. We both experience problems with wifi also here. I have several draytek routers, all giving problems.
It seems to become a bit more stable if you set the Channel width to just 20 MHz, in stead of 20/40MHz. And use WPA2 only, not a mix of WPA and WPA2.
These two changes made the connection a bit more stable for me, but i'm not 100% convinced yet.
mine doesnt hv any issue with wifi, but for my cell signal, it changes between 3g <> h <> h+ alll the time, anyone too?

I posted a solution for this in the known issues thread but I thought I'd repost here in case you missed it.
I was having similar problems but found that if I disabled the Wifi Power Save Mode I was back to blazingly fast speeds and no dropped connections.
I had to go into Service Mode (dialling *#0011#) and hitting Menu => Wifi and turning off the option for power save mode.
Give it a try. It fixed a couple of other guys problems as well.
Am giving this a go will report back.
That worked but battery drainer . Have put it back on and set wifi to off when screen off. That has helped loads.
Worked for me too, and trip really is unnecessarily complicated and hidden to get something that should be working out the box.
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
Hi, hope I've posted in right place apologies if not!
I can connect devices to my phones hotspot no problem but for some reason the connection/speeds between my phone & PS4 is really low. D/load sits approx 400 kBps and u/load 3 mBps (wifi or USB). I have tried alternating the bandwidth on phone (2.4 & 5ghz) and different channels but no improvement.
Normal tests on phone's 4g (EE) sit around 60/15 mBps.
My previous phone (s6 edge on O2) comfortably worked around 20/4 mBps. Issue is def between Mate 10 Pro & PS4.
Any help gratefully received!
That's very strange, have you tried another device say laptop to see what speeds you are getting?
Sent from my BLA-L09 using Tapatalk
When the home other devices work fine, speeds nowhere near as high as phone's 4G on its own but decent enough ~10mb. At work at minute and signal not strongest but ipad still registers ~4MB download when on hotspot. Still plenty more than PS4 gets. Huawei tech support no help, just passes me to network provider.
From Huawei perspective it's not a Mate Pro fault as it works with other wireless device fine. I will test my PS4 today and report back on my speeds.
Sent from my MHA-L09 using Tapatalk
I do suspect it's something to do with my handset not necessarily the phone model just hoped they may offer some light as to where I should make changes etc.
Thanks I'll be interested to hear what you get and maybe if you could let me know what the settings default too when you connect so I can check that be great!
hotspot and mobile network functionality issues
For some strange reason when the mobile hotspot is turned on the mobile network on the phone which allows me to send text messages and make phone calls seems to fail. Has anybody experienced the same problem? Well I'm previous phones I can have a hotspot on and have up to 4 maybe more devices connect it and still be able to use the phone at the same time, i e: text messages, phone calls, multimedia messages, playing online games on the phone, looking at videos on the phone, even the internet. I think it may be the mate 10 Pro because I have not experienced this problem with any other phone.
Iam experience the same problem I tried everything . nothing helps. I see that iam broadcast my hotspot wifi signal. But no device can connect.
No worry brother, I just back from huawei services center and they well notice Hotspot issue and promise will fix it on next update.
Hey guys,
my Mate 20 Pro won't connect to 5ghz wifi.
I always need to adjust settings in the menu of the router which is inconvenient.
I of course can't do that at every place that I go to.
Especially since many people don't even know how to get there and their log in data.
Is there a fix for that?
Does even anyone else have that?
I have connected my M20Pro to 2 different 5 Ghz wireless access points without issues, both using WPA2 security,
I am having a slightly different problem. My phone will connect to the 5ghz network, but once I am more than 10 feet away the speed drops to almost nothing. The 2.4ghz network off the same router is unaffected. I have tried factory resetting my phone and resetting the router and nothing has resolved the issue.
You can make sure that the WiFi of 5G is hidden， Make sure WiFi is household or public？
I use 5ghz wifi at 3 different locations, no issues. 2.4ghz always has a greater range though. Any issues are with the routers.
Sorry for the late update.
I've got my device replaced because of the green lights at the edge and around the notch.
WiFi works perfectly now.
I get up to 100% of our bandwidth which I haven't seen in any other mobile device.
For me, asking Vodafone to exchange the device was the easiest and quickest way.
I've exchanged the device right in the store and was ready to go.
As I've heard (but didn't need), Huawei offers a similar replacement service.
I was told that I would be contacted later by the Huawei online chat but wasn't since Vodafone was quicker.
This was in Germany. Might be different in other cases and especially countries.

Like I've said, I've got a replacement device because of the green screen issue.
The new device has the best wifi connection I've ever seen.
Don't know if it was the old device or a software issue though.
Had my x1 for a couple of days now and lots to like about it however I have noticed that it seems to have a very weak phone signal reception.
I am on three in the UK and in the normal areas I travel I have never noticed an issue on my other phones with it struggling to hold on to signal bars.
Anyone else have this?
Signal bars mean absolutely nothing. Many oem even show full bars even when there is actually no signal.
Better install cellmapper app that will exactly show and record the signal where you travel.
Also, do you have 3uk volte working?(calls over 4g network)
Well all I can say is that I live less than a mile from the nearest mast and would nearly always have full signal bars on other phones yet on this phone it drops on and off 1 bar.
I will download the app you mentioned and see what that shows
I've had this problem with numerous Sony phones over the years, always poor signal compared to Sammy's, Pixel's and iPhones that I've had. Same issue with the X1 I have now, always on WiFi calling and no signal, my Pixel 3 XL would be happily sitting on 4G.

Glad it's not just me then.
I do remember having this issue on a previous Sony phone also but can remember the model now. It's been a long time since I had a Sony but thought this one was going to tick every box which it almost does apart from having reliable signal reception which is really should be a must!
Is there anyway they can improve this with software of are we stuck with it due to hardware issues?
I'm in my 14 days returns periods at the moment and like everything about this phone apart from what it should do first and foremost
I am having the same problem, I'm on EE and my LTE keeps dropping from 4 bar's to 1 bar then nothing which causes me to lose data connection. It then jumps to 4 bar's again and then repeats this over and over. This is happening at home where I always have full reception. I have tested my sim in 5 different phones all have full reception and don't lose connection only my Xperia 1 does! Any help would be appreciated.
Same problem for me. I switched my SIM from Galaxy S8 to X1. S8 has 4 to 5 bars while X1 struggles with getting one bar at home.
Ffs... The bars mean nothing. Sony phones take into consideration RSRQ(signal quality) and SINR(s noise) values of the signal. Other oem don't. The actual signal power RSRP (do not confuse it with bars) is same or better on Sony.
Xperia 1 has most advanced modem and antenna setup of any 4g phone. 4x4 mimo even on low bands (first to have it).
3uk and ee are special in the sense that they need phone to support volte to get access to their low band spectrum(band 20).
So make sure you have volte aka 4g calling enabled and check with apps like Netmonster or Cellmapper the band and RSRP of the signal. Then compare it with other phones at the same place.

If it's as simple as that why is it not enabled on this phone already?
I think what you seem to be over looking is the fact that I and others here have said that yes the bars are lower than other phones and flutter slot but also to the point where they drop completely and give no reception at all. A situation not faced on other phones.
Can you explain how we enable this missing band so that the phone can provide a more reliable/stable reception
Does your phone have 3uk volte(4g calling) enabled? Phone should stay in 4g during call. If not then you are out of luck.
ee users can install EE firmware to get Volte working if it's not already . newflasher on xda helps to change firmware.
And please compare signals with abovementioned apps.

If you're having signal drops / dropped phone calls etc... I get it. But Sony is historically notorious for showing lower signals than others on those bars. However, as stated, the bars are pretty meaningless. I've owned many Sony's, and while the bars are lower (sometimes all empty), I still have signal in all the places I should. YMMV.

I don't honestly know. My phone was purchased sim free from carphone warehouse and I use it on 3 network. The phone just set itself up. How would I check this? Is it something listed under network settings?
It's so frustrating as I'm really loving a lot about this phone but just want it to be comparable at least with my other phones I've used with call reception
those who are having signal problem, are you using EE network?
I saw lots of people with EE reporting this issue on official sony forum.
Got mine yesterday from Vodafone and signal is perfect !

Yes
I also have only 1 bar... Orange.
If you are EE UK user, then you need EE firmware on your Xperia 1 to get best network compatibility(Volte and low band support because of it).
3UK users probably need also 3UK firmware but that does not seem to exist yet.
This weirdness of low band access is specific to two UK operators. Everywhere else the device is fully capable of best 4g experience.
Wait Next update

So for those of us on three network but purchased the phone sim free are stuck with the problem as three do not sell this handset themselves so unlikely to release any firmware for it.
That does not look good for me so I think I will need to return within my 14 days.
Shame.
There's definitely a network connectivity issue with the XP1 right now though. This seems to affect only XP1's on the EE network, which were *not* bought from EE direct, i.e. ones with stock firmware. (e.g. mine!)
The symptoms are that periodically, first the 4G symbol disappears, then the signal goes to zero and you've lost the internet. Then it reconnects back onto 4G again. Sometimes this repeats 3 or 4 times in succession. The whole thing takes from 5 seconds to maybe 30 seconds depending on how many re-tries.
You can go for maybe an our or so without a problem, or sometimes it happens like every 10 minutes.
And here's the key part: this happens wherever you are, even on a full strength signal. As far as I can make out, this affects ALL XP1s with stock firmware on EE. EE say it's a Sony problem. Sony say it's a network issue. So we are all stuck.
Does anyone know of a suitable network logging app, which will log 4G disconnects and signal loss, so we can provide evidence to EE and Sony?

(My phone is fine with a Vodafone sim. There's something specific to the phone firmware/config - timers, buffer sizes, packet sizes - whatever - and the EE network. But right now, on EE, it's unusable.)
