Since a few days I'm running the ICS stockrom on an unrooted Note. Before on the GB I was have not the best reception with Wifi, but it was working. Now, with ICS, my Wifi is connecting/disconnecting/connecting/and so on within a matter of seconds. I'm experiencing this on multiple Wifi networks. Therefore I would say it does not concern the settings of my Wifi network, also I'm practically sitting on the router (channel, reception can't be issue).
I've installed ICS via Kies and have done an additional factory reset today.
Does anybody know what could be the cause of this? And, more important, how to solve it?

Others have had similar issues - try reflashing the same modem from here:
http://forum.xda-developers.com/showthread.php?t=1645202
I found that wi-fi and data both worked better after flashing the modem a second time.
Thank you very much it seems to be working!!
I had to look to find out how to get the phone in download mode, but got it.
Sad to say I did an unneeded factory reset this morning, but yeah it is working now!
I've been also noticing momentary WiFi disconnections ever since I upgraded to ICS.
I'm using MyPhoneExplorer to transfer files wirelessly to the device (not via USB), and ever since ICS it has became an unreliable way to transfer files. If I transfer a big file most chances are that the WiFi connection will drop during the transfer, causing it to fail.
The connection is restored immediately but then I have to restart the transfer process as it halts when the connection fails.
I have excellent signal level (physically located close to the Access Point), I tried flashing the latest modem firmware (XXLR1) - twice, I've set "2.4GHz only" in the WiFi advanced settings, all to no avail: I still get these connection drops.
The same setup (phone, access point, etc) has all been working well in the past with GB. Now with stock ICS it performs poorly.
Has anybody got any information about this problem? Been experiencing similar problems?
Thanks!
I've been getting this issue too but it seems to only be with our virgin router, all other devices connected to it are fine although the signal is a bit crap on them to its at least stable
I tried the modem flash etc but no improvement, I'm pretty sure its the ****e virgin router

At my side it seems to be working better now, steps I've taken (in this order):
1. Flashing new modem
2. Enter fixed IP address for my home Wifi
3. At Settings->Wifi->Advanced->Leave Wifi on when enabled
Especially the last seems to have done me good. I have it working in combination with BatteryFu so it does not consume my complete battery.

Well, the AP that I had problems with is a relatively recent D-Link 802.11n router. Nevertheless, I tried connecting with an old Cisco 802.11g router, and lo and behold - connection is now stable.
So, looks like there is indeed some interoperability problems but I won't dismiss this as a "****e <X-company> router" - as the same router is working well with other clients, and moreover, was working well with this phone when it was running an older GB firmware.
My conclusion is that apparently somebody at Samsung / Google has broken the Wi-Fi drivers, interoperability-wise.

You probably mean leav wifi on when screen is off? My phone is already set this way... Anyhow, thanks, but it looks like this is a problem with a specific router as I wrote in the first part of this message.
I seem to be having pretty severe wifi issues on networks that are composed of a large number of routers (i.e. campus/business networks) where going between routers will result in the phone believing it is connected, but not being able to send/receive data. This is evidenced both by the lack of notifications/apps working, as well as the wifi icon in the quick toggle panel being orange (which indicates no data being sent/recieved, I believe) despite having full signal. This means that without any external indication that anything is wrong, my phone essentially does not work anymore until I turn the wifi off and back on. Previous phones (galaxy nexus, droid) as well as computers did not have this issue on the same network.
Has anyone else noticed this problem, and if so, found any way to get around it other than remembering to reset the wifi power every time you move between areas?
It sounds like there are multiple WAPs all using the same SSID, and Android is not requesting a new IP address when it disconnects from one WAP and connects to another. You could probably work around the issue using Tasker, and have it toggle Wifi off and on again any time Wifi is disconnected. I you go that route I would recommend using the trial version available from the developer's site, or one of the many similar apps that are available in the Play Store for free.
There may be something more to this though. Hopefully someone else has another idea.

I'm having the same issues both out in public and at my home. This issue didn't seem to exist prior to 4.4 update. Now I'm constantly having to toggle my WiFi on and off or toggle airplane mode and also hitting the symbol down at the bottom left on my phone and on my router at the same time. If someone has any information to correct this would be great. Like I said I never had this problem prior to 4.4.

Thanks for the suggestion! One question though: does the wifi actually "disconnect" when there is a handover between two routers of the same network? Is a handover while constantly connected something tasker could detect?

As far as I know, Android doesn't "roam" seamlessly from one AP to another even when the SSIDs are the same. I'm pretty sure Tasker would see this as Wifi being disconnected (albeit briefly). You could then tell Tasker to turn off Wifi for 5 seconds and then turn it back on again.

I finally got around to making a tasker script to do this, and tried it out for a few days, but unfortunately it does not seem to detect the changing between the different routers on my institute network as having the wifi disconnected, and thus doesn't solve the issue. It was a good idea to try though!
I've cross-posted the issue at the link below in hope motorola will see this, but if anyone knows a better way to report this, please let me know.

Hello all, so yesterday my N6 started doing funky things. My data refused to turn on (it had the exclamation point next to signal bars). I couldn't send/receive text messages and then my phone froze. I rebooted, then found out ALL of my saved WiFi passwords and all of my saved networks had disappeared. So what gives? Anybody else have this issue? It sucks because I had a few hidden WiFi networks saved on my phone, and now I'm having difficulty finding them again.
I have had this happen to me as well and its extremely annoying. the quick fix would be to do a factory reset and hopefully it will restore your passwords. Happened on my N5 as well.
That's what I was afraid of. Having to do a factory reset again. Ugh! I've done more factory resets on this phone than I have with all my phones I've ever owned, combined.
Yea I will probably do one when 5.1.1 drops
Hey I just had this happen too. Phone froze then rebooted and WiFi saves we gone (grr). Open networks or hotspots like xfinity (I have xfinity so I use my sign in from the account to access them) are still saved...weird. I guess those are saved elsewhere like part of the webbrowser (chrome)?
Very common with lollipop. no fix, but you can back up data...misc...wifi...wpa_suplicant.conf then copy it back when it happens.
For me I tried that and the system would just overwrite the file
Is everyone here encrypted? I am reading that might be an issue. I am.
Hmmm. Maybe as it happened on my n5 and it may have been encrypted at the time

5g or 2.4g or both? I've had some strange on and off issues with WiFi and I've narrowed mine down to 5g. When I connect to my 5g network, I get drop offs frequently. Never lost a password but when I'm on my 2.4g network, the issues subside.

I've had enough WiFi anomalies with 5ghz, that I've disabled it on my router. Everything works without problem on 2.4 GHz for me.
This has absolutely nothing to do with 5GHz, nor encryption. Its just a glitch in wpa supplicant that it occasionally deletes its config file.
Also, if you experience this problem, I can't imagine what anybody suggesting a factory reset would be thinking, but that definitely won't help get your saved passwords back.
When you factory reset. They will download the wifi settings from Google servers on set up. This has worked for me in the past.
I also have this issue... Any fix?
Not exactly certain where to post this (as I am not altogether certain the cause) so if mods have a suggestion to move it let me know.
I have a rooted Tmobile S6 (not rhe edge) running Sick as Hell custom Rom version X w/ Unikernel v9.
Periodically my WiFi signal will display the ER041 - DNS (or less frequently the ER081) error which I believe is related specifically to WiFi calling.
My GF has the exact same phone and the same setup (I think she has WiFi calling enabled as well).
I have run some tests previously where I turned WiFi calling off and still had hiccups with the WiFi (both home and at work).
It seems that when I clear the cache and reboot the issue resolves itself but only short term before I have to do it again.
No one else in the house is having WiFi issues such as me and I cannot seem to figure out if there is a setting that is throwing things off or what.
Any help is greatly appreciated.
Mine does this too but it usually clears itself up within a minute or two.
OP, check your IP address to see if your phone is getting an IPv4 address. I don't know why, but my phone was having major issues with this. I still haven't figured out exactly what the issue was; I was on Sow Nice, flashing back to stock solved the problem. The phone was getting an ipv6 lease, just not ipv4, for no apparent reason.
If that doesn't help, I would advise setting network configuration manually. However if ipv4 isn't working, this may not solve the issue.
WiFi Issues
Alright gang I need some brainstorming...and curious if any other T-mobile Galaxy S6 users are experiencing this issue. I don't believe it is ROM related but thought I'd post the inquiry in here anyhow.
Specs:
T-Mobile Galaxy S6 (SM-G920T) rooted with Sick as Hell X and Unikernel v9.1.
Baseband: G920TUVS3DOJC
Issue:
WiFi is intermittent (both work and at home). WiFi will be running fine on this device and also on my Kindle Fire and at some point WiFi on my S6 will stop working. The WiFi icon will still appear and the up/down arrows will flash but I can't pull up Google search results, YouTube videos, etc.
I get a ER041 - DNS error which is related to wifi calling but I think this issue is in fact DNS related (I've googled and googled and am just not entirely certain, if it is DNS related, exactly how to change settings to thwart this issue going forward).
If I run a speedtest I will get a "Network Communication Issues" message. If I turn off WiFi and then turn it back on the connection is still broken.
HOWEVER, if I clear the cache and reboot the phone, it will connect to WiFi for a period of time until the connection gets broken once again.
My phone seems to be the only device experiencing this issue. I have booted into Safe Mode and the issue still occurs so it doesn't appear to be app related. The Smart Network switch has always been off as well so I know that isn't the culprit.
At work I'm not going to be able to check the router settings but obviously I can at home (at home 4 other users connect to WiFi no problem).
There has got to be some sort of tweak/button/setting that I'm just not catching that is causing this. It is irksome.
I recently did a factory reset but the issue is still persistent. Scanning the interwebs this seems to be a pretty common issue with the S6 and Lollipop.
Any ideas??

Keep in mind, the other kernels are international
source.
EDIT.... also uni kernel adds a default.prop in system that has ro.securestorage=false when it needs to be set to true for USA devices
I'd say at this time I can rule out the kernel (it's a been a few days now running Twisted v7.1). I honestly think it is a Samsung bug. Not just S6 users but Galaxy S7 users are now reporting the issue as well (there is a thread over at AndroidCentral).
Just like myself, those users are reporting that Smart Network switch and Blutetooth and the like are turned off/disabled and yet the problem persists.
I've had WiFi issues on an s6 edge. But I figured it out that if I'm near my microwave and it's on WiFi dies on the phone. Soon as the microwave goes off it works fine ?

Huh. Not the case in my situation. I've got a microwave but it's in the basement and rarely used.
Has anybody had any problems with their WiFi not connecting? My device seems to fail to connect to wifi after a couple of days and just sits trying to connect. Toggling WiFi doesn't seem to resolve it, and I have to reboot the entire phone to get it back online.
No problem here.
Connects very quickly, never seen it fail to connect, even on my works dodgy BT homehub 3, which used to tie my old Z3 compact up in knots..
Yep.I thought that Snapdragon 835 cause this problem. Xi oami 6., ZTE z17 and Op5 had the same question with WI-FI connection.

I have a sd835 s8 and I haven't had any wifi issues whatsoever since launch. It's a sample size of 1, but I don't know if it's truly due to the sd835
I haven't had any WiFi issues. In fact my WiFi connections have improved using the XZ1 compact over the X performance (the X performance dropped its WiFi connections 3 times during my data transfer to the new phone)
I've had my XZ1c for about a week now (European model) and it connects to my home network (5G) normally. Signal strength is fine, although the galaxyS6 it replaced definitely had superior reception. I do have wifi issues, but only when already connected to the network. When the phone is asleep (screenlocked) it seems to lose an active connection. The wifi connection should be on at all times, even asleep. It will show the wifi symbol, but data apps don't load, and it will have lost the connection as remote for spotify connect (playing on my reciever). It will also switch to mobile data at random times with normal wifi signal strength (even though I toggled this function off in the developper settings).
I'm not sure if this is something that can be fixed through system updates. I haven't seen any forum posts with similar problems though, so I'll try to document what is actually happening before I contact Sony support.
I bought the US version and flashed the UK firmware to get the fingerprint reader to work. No issues whatsoever with this phone. No Wi-Fi issues, overheating, signal strength, battery, nothing. Everything works just perfectly.
Same issue here. Mine is Europe (NL) version. The upload and download speed can be very unstable. And especially when I take it a bit far way, even you see that it's connect to the wifi with full signal strength, it said internet is unavailable.
I'm not sure if this related to the system update of last weekend or not.
Further to my issue. My phone will drop wifi connection and repeatedly try and connect - it usually cannot see any other networks at the time. Restarting the wifi on the phone, or rebooting the access point do not help. Running a packet sniffer on the LAN shows no activity, which indicates the issue is to do with wireless handshaking.
The problem occurs every few days and the only way to resolve it is to reboot the phone, which fixes it instantly.
I contacted Sony and they told me to do a complete reset on the phone, this didn't work. I updated my findings and pointed out that it's seems to be a firmware compatibility issue. Of course, you only get to talk to first line, and as a reset didn't work, they want me to send it off for a warranty repair (which of course will be returned with "no fault found" as no doubt their wifi will be different enough for it not to have been picked up on day 1 testing).
I'm currently trying to gather a bit more information on the fault, e.g. does it only happen on my home wifi etc. I've disabled channel bonding but that didn't help, and I've not jiggled my DHCP settings after seeing plenty of posts describing wifi problems on Oreo for other phones.
It doesn't happen frequently enough and I don't have the time to delve deeply into the network to identify the cause.
One interesting thing was that it went funny at home, but it was working when I got to work. When I got home it still couldn't connect. So I suspect it's to do with a particular compatibility issue somewhere.
no problem here conecting to 5 and 2.4 wifis...

So far my wifi has been fine...
Mine is worst, i couldnt get it to connect at all but all my other device including xperia xa, xzp, laptop, Ps4 PS3, everything connect without any issue whatsoever, already excahnged once and still the same.
Think mine is struggling with either a single access point or VLANs. I need to dig further, but that requires buying a new AP - this phone is getting more and more expensive!
exactly same issue as Dashers describes with my XZ1c. I am not watching it closely, but it seems that it is hapenning after around 2 days online. Never happened before on same network with my previous Z3c, which had run months without restart and any problems whatsoever (till its display died

I have more or less the same issues, and a reboot always solves it. It happens with both routers form ASUS and Draytek.
Additionally I see issues with Spotify connect dropping or not being found on my Sonos (hardwired to LAN), but not so much to Chrome Cast Audio on the same network.
I don't have a problem connecting to wifi, but I seem to have a different issue. Even though wifi scanning is toggled off in settings, my phone still seems to be scanning according to Battery Historian. I think this is one of several things contributing to my high idle drain. Does anyone else have this problem?

Yes, wifi and BT scanning are both turned off in settings and have been since the beginning, but both seem to be happening anyway according to Google's Battery Historian tool. When I go back in to see if they've been toggled on by an app or something, they still appear to be off.

I have this exact problem. One second its 100% signal and is workin as expected. The other second it just drops and tries to reconnect like crazy. I have even had moments when i am unable to find my wifi after said disconnect. All my other devices is working like normal on my wifi. Using Asus n66u 5ghz.
I have been having the same issues as mentioned above with my XZ1 compact(european). My issues with dropping wifi signal seems to be happening when there are two different wifi signals to choose from. They are both on my local network. One is an extender due to the size of my house. When it can detect both signals, it can't make a decision on which one to choose. Once I remove a device(forget wifi device), it stays connected to the other with no problem. Since it isn't trying to compete with the other.
Has there been any improvement on this issue?
