I know there has been a lot of wifi issues with sgn2, most of them already sorted, but this one is different. Wifi was working fine for me but yesterday when I tried to tether the wifi connection via bluetooth to my PC, wifi got disconnected. Reconnects after a minute or two but then it gets disconnected again. Later when I manually tried to connect wifi, bluetooth tethering stopped and it wouldn't start back. Had to reboot. This happens every time. Was working fine the day before yesterday when I figured this could actually be done. I'm on GT-N7100 non rooted stock ROM 4.1.2 build MA6. Anyone else facing the issue? Please check and reply

This started happening to me couple days ago. My phone is connected to wifi at home, and whenever I want to use my phone after its been in idle, everything looks normal. The wifi signal is there, but there is no data, I cannot check email, browse internet, anything with data. Only way to fix it is to reboot or turn wifi off and then back on. Everything is fine when I'm on 3g, there are none of these issues. I am on Calk 2.7 (not 2.8) with the latest kernal, EL28 (I think thats the latest).
If I have an app running in the back that is constantly using data (google music) (recall, ONLY on wifi, NOT 3G), the app stops working whenever the phone goes into idle, I guess. Basically leaving a data consuming app ruining in the background did not help the issue.
I have tried searching, and some other people have experienced the issue on different devices (NOT epic touch), but no threads offer any solution(s).
Any help would be greatly appreciated.

I had this issue on my previous epic touch and I took it back and exchanged for another one and the one I have now doesn't do it. It had the same problem u describe. Might want to check your router first though since it just started. Mine always did it and it did it on other Wifi networks. Good luck.

I've seen this happen on four different E4GTs. It seems random and only occasional. I've seen it on EG30 and EK02 stock, I haven't tried other "modems" or roms yet. I'm not sure what causes it, but a quick wifi toggle seems to fix it. Seems like the wifi radio just sort of "freezes. " Wifi sleep policy set to never, doesn't seem to make a difference. Minor annoyance.

What baseband are your running? Have you tired another baseband?
I didn't think the modem has anything to do with wifi. I have this issue on certain wifi networks I use. I have made tweaks to see if it is security settings or what but haven't figured out a pattern yet. I use a wifi widget and it looks like DHCP hangs up cuz it won't give it an IP. I reboot the wifi router and it works right after evertime. I will sometimes powercycle wifi on the phone and it will work. I really think it is a wifi router setting for the network but not sure which yet.
Hi,
When im using my S2, there would be this annoying pop up saying "Connected to Wifi ..." like every few minutes to maybe an hour. I looked on Google for fixes but I could not find any. Than I noticed that right before it showed the pop up, the wifi bar was gone so I'm guessing that my wifi connection has been dropped?
So it keeps disconnecting and when it reconnects it has the pop up "Connected to Wifi Network ..."
Does anyone else have this problem? Its new so no need for a factory reset.
Its on the stock ICS update (4.0.3) and not rooted or anything.
A friend told me that my baseband could be corrupted, anyone know how to fix that?
Reflash a new radio.

I have the same issue and i have noticed it only happens at the same 2 places, so it leaves me to believe it is a router issue. At home all i did was unplug my modem and router for a couple of minutes, plugged them backed in and haven't had any more issues. But i would pay attention to were it is happening.

Same problem...
Hi I am also facing the very same issue with my gs2 when I switched to a new wifi router recently. I did not have any issues earlier. I tried some trials and noticed the following..
1. The problem exists with this particular router only.
2. there are other devices working normally in harmony with this router
3. The problem disappears and everything gets smooth and cool when one more device gets connected to the router(wonder how this happens)
4. Same issue with my galaxy tab
I have gs2 with ics 4.0.3
cisco dpc2320 cable modem with wifi router
Any ideas to solve this...???
Its been a long time since ive been on here so i kinda need help on this. My bros evo for some reason doesnt want to connect to the wifi. All it does is scan then connecting and then right away disconnect...it repeats the process several times before it stays disconnected. I was tryin to tether my data to him using my GS3...my other brother didnt have a problem connecting to it with the ipod. I flashed a new rom for his evo with no issues. Clean install. Still no go with the wifi. The evo has no mods. Jus the rom n the kernel it came with. It mighg b a hardware issue. Not sure. Any ideas?

Try resetting the wifi router. I had the same problem the other day.
hi
since yesterday i'm having problems with my wifi connection, every time i turn on the wifi on the phone he checks for connections and for 1 second he can see my wireless network but then i can't connect to them, i tried connect to other networks but the same thing happens, i tried another rom (i'm using miui 2.3 and tried cm9)and the problem continues.
sometimes i can successfully connect to my network but in 5 minutes the connection is lost again.
I had this same thing happen on my phone a little more than a year ago. I tried everything but it didn't fix anything. I had to send it in and get a replacement.
if i change the radio would this do anything?
have you tried a full wipe. I've got this problem at the moment.
I figure either a full wipe will fix it. I can't do this at the moment because there are too many numbers in the phone
Or
The wireless antenna got disconnected when my gf dropped it

i already did a full wipe and installed another rom
the only thing i didn't tried was another radio
Hello, I've been having a problem with wifi on all new 4.2 roms over the last week or so. For an unknown reason, I can connect with phone data but attempts to get on wifi have been mostly unsuccessful. WiFi just says "obtaining IP address" but eventually times out and starts authenticating again. I have tried wiping everything with 3 different roms and now I'm on Tasks AOKP rom (12/23 with stock kernel) and having the same problem. I've tried all available Canadian modems with the same results (data is best for me on LLH1 though). If I switch back to CM10 (12/16) my wifi works perfectly.
I can get wifi if I mash the on off a few times as it usually causes a force reboot and when it boots I get wifi about 50% of the time. Attempts to modify router settings and reboot my hardware have been futile.
Anyway, I'm hoping one of you is interested enough to peruse the log I saved using "wlan" as a filter. I don't know if that's the best filter but it seemed to show the gist of it. Thank you in advance!

I'm having the same issue task aokp 12/23. Also, if I try to toggle the wifi in the settings screen, it reboots the phone.
However you might try to do this. This morning, I flashed the 12/23 kernal found in task's op. I can toggle wifi on/off now without issue. But i'm not anywhere near wifi to check if it connects.
I found WiFi at target and I'm posting from it. It connected right away.
So, flashing the kernel alone after flashing the ROM, fixed my problem
If you were having the same problem as me, I have to wonder if disconnecting and attempting to reconnect will work.
I downloaded tasks 12/23 underwear kernel, booted to recovery, wiped cache/davlik, flashed only kernel, wiped cache/davlik and rebooted. Tried toggling wifi a dozen times, phone crashed, rebooted, still can't get IP. I imagine that if I play with it long enough I'll get wifi back temporarily, but I use wifi more than data so I'd like it to work better if it can.

Back at home, I can't connect to wifi.
Edit. randomly tried it again, and it connected instantly.
Yeah. I've spent a lot of time troubleshooting router settings (channels, signal type etc) and have thought on several occasions that I had fixed it, but shortly after found that it was a one time connect. I have a spare router in storage that I'm going to try, soon, and that should help me decide if it's a router problem or a JB issue.

Well, no need to play with the router I have managed to obtain flawless wifi, but not on Tasks rom. The 12/27 illusion rom works great, but I can't get mobile data working on it. I switched back to tasks with hope that a future update sets the wifi straight.

I tried the official CM10.1 12/28 nightly this morning and quickly discovered that wifi was working great. I was able to turn it on/off multiple times and reboot without issue. I flashed a different Canadian modem and reflashed tasks AOKP rom (no kernel, no gapps) and wifi was broken again. That logcat makes me think it's something to do with how the rom is handling DHCP requests, but I'm a noob and hardly know anything about any of this stuff.
A nan restore to my AOKP rom got all my stuff back, but it's takes me a solid 30 minutes to get wifi connected.

I updated to tasks AOKP 1/1/13 and my wifi is working perfectly! I considered switching back to 12/12/23 to see if it was the build, but who cares?!
This issue is resolved.
