[Q] Wifi stopped working? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Just wondering if anybody else had this problem
I was running on superlite 5.1 as my daily driver, working perfectly fine for weeks. then this morning, it stopped connecting. it stops on obtaining IP address, and after a few minutes, it says avoided poor network connection.
I tried re-flashing superlite, and flashing over to CM9 and smoothie. same results. i'm scared its a hardware problem?

Have you tried flashing the radio?

My inspire has wifi problems

Ok I have had my inspire for about a week now and yes it's rooted. I have been having problems with my wifi saying unable to scan for networks. Go into advanced settings and mac address is unavailable. And when wifi doesn't work I am also not able to use tethering. Sometimes everything works fine and sometimes it doesn't work for hours. Suggestions would be appreciated

Have you flashed anythingI, or are still on stock kernel.. or have you ever flashed a kernel?
I have flashed 4 different roms and get the same issue every time. I am new to the android world so I have not flashed any kernels by themselves.

Stock wifi issue?

Is anyone having issues with the wifi not working at all on stock?

my girl's g2x will somtimes say "error in connecting" when trying to switch to wifi. Usually a reboot clears it up, tell me this is not another issue...lol.

Wifi works flawlessly on stock. If yours isn't working you should get it exchanged.

I had an issue with it going to the mobile data connection randomly and never going back to Wifi even though it showed the wifi icon.
Using root explorer to remove "My Account" fixed it per some suggestions on this forum. Before I did this a reboot was the only way to fix it.

Problem connecting to data

i sometimes find that my phone has no data i am still on stock have no rooted yet but am running 2.3.6 It will not turn on by its own i have to power off phone to get to work just wanted to know if any one else has had this problem or is it just me

your problem sounds like an apn issue or provisioning problem.
are you using a stock phone? what apn is selected?

Same problem here..I am not stock rooted. seems like an Lte issue.

I have a similar problem. I loose data out of blue. Called Att and they informed me that my data was removed for some reason. They reconnected but ever since than, I loose data for no reason. I have to reboot the phone. Even than, my data works for only 10-30 mind and disappears. When that happens, I have to call ATT and the disconnect my phone and reconnect and it works fine for a while. I've called them 4-5 time in last few weeks. They think its the phone. They are going to send me a replacement.

[Q] Wifi calling is AWFUL since CM 7.2 stable

When I flash 7.2 stable or any nightly after it, wifi calling quality is AWFUL. It's nearly impossible to understand what the other person is saying due to dropouts and static and such. It kind of sounds like cell calling when you have almost 0 signal (dropouts, distortion). Cell calling works and sounds fine, not wifi calling.
If I flash back to 20120603-NIGHTLY-p999, wifi calling works fine again. And YES, I do have the new March baseband.
I've tried this on multiple wifi networks that I KNOW have plenty of bandwidth, and the results are the same.
Anyone else have this issue? Solutions?
I'm having the issue as well even more so I'm having issues connecting, if/once it does connect I get static as well.

Yup, I'm on LG-P999-V21y, which I think is the only one that works with the March baseband.
Would RIL affect wifi calling anyway? I assumed RIL only had to do with the cell radio.
I was on 20c for some reason. I just switch hex to 21y hopefully that'll help.

I keep getting this at my work I changed nothing from yesterday ans it was fine... and whn at home I got it there also. Which is fine I get service at home but not at my work.

I had the v21y ril for awhile but I had noise and connectivity issues...
Now I'm just using the default (v20c) ril...connects no problem and noise issue went away....

I'll look into it next time I'm at work at that location... It's a College arena with about 10 wi-fi routers all over the place... still Wi-Fi calling at my house where nothing has changed is acting stupid... just takes minutes to connect at times, and if it connects it sounds weird and distorted... I went back to a OTA GB rom and nothing was wrong with wi-fi calling, so i dont know... Thanks for the link though.

stock 7.2 kernel -- it works fine for me, if and only if you
(1) are on 21y baseband
(2) use GetRIL to make sure you have 21y RIL
(3) flash Owain's fix for new baseband
(4) use Trinity ELPmax kernel..
Then it's fan-frickin-tastic.
Otherwise, it works, but you have to reboot all the time to keep it working.

[Q] WIFI ISSUE SCH-i705 (Galaxy tab 2 7.0)

Would anyone know why my WIFI works perfect when Bluetooth is not on, then WIFI gets authentication errors when Bluetooth is turned on? Soon as I turn off Bluetooth WIFI works again when I reconnect to network. Thanks.
I've not noticed anything on mine. Have you done anything to it such as root/unlock/cwm/ROM?
Its unlocked, with CWM and doubleshot 1.5, but unfortunately I cant remember if it was doing it when it was stock.
Have you tried factory reset? Even reflashing the ROM? I just tested it on mine and it works fine. If not, you may have some bad hardware.
I just tested BT and Wifi on mine with 0 issues. Paired it with my s3 with wifi browsing a few websites and it didn't break.
Tried reflashing, ended up returning it. Thanks for quick reply and help. New one works perfect.
I messed up and didn't unlock the boot loader... Should I wait for stock firm ware or take it back to Verizon... And if so what should I say
