Wifi just randomly broke - AT&T Samsung Galaxy S II SGH-I777

Hey guys. This morning my Wifi was working fine before I left home. I came back and now Wifi won't work at all????? I thought it was my rom at first because I was on a hellraised rom (checkrom). Ps. I did not and have not flashed anything for the last couple of days.
I flashed three roms in total from here in the att. Unnamed, serendipity, and sho stock. But the result was the same. I even tried different kernels but it just will not work.
Any help will be appreciated.

Router up?
Some flashes have been known to dork up the wi-fi until a factory reset wipe.
Just a thought.

OK I'll try that. But yes my wifi router is on. It's just when I turn my wifi on my phone it just shuts back off.

Exact same thing I discovered when I flashed.
Would turn right back off before discovering anything, and also too quick to manually add my node.
Under, Settings/Privacy/Factory data reset.

OK. I just did that but it still does the same thing. Do I need to flash a different rom and then do it again or what?

O yeah and I had restored a stock att rom in clockwork when I had did the factory reset if that has anything to do with it not working.
Sent from my SAMSUNG-SGH-I777 using Tapatalk

Not sure.
I was on UnNamed 2.2.1 when I flashed back to the Return-to-stock rom.
That's when I saw it. A quick factory reset did it for me.

It's just random. I think I'm gonna take it back.

Same thing happened to me after installing the Siyah Kernel, very frustrating.
Edit: After installing Unnamed 2.2.1 the issue seems to have gone away (haven't been able to a wifi network, but wifi is staying on now). Will update later.

Android WiFi tether not working

Hey guys I was searching and didn't see this in the forums. Recently I've been able to use WiFi without a problem. All of a sudden today it stays on for a few seconds than says what the heck? Your phone took over WiFi connection! Shutting down WiFi now! Any idea what's going on?

Are you using Green Power or Juice Defender or an app like that? If so, turn them off.
Nope.
Sent from my ADR6400L using Tapatalk
I've used the newest tether app and barnacle and neither works. Tried settings that other puerile have used, ones that worked for me before, uninstalling, reinstalling, wiping cache, nothing wants to let it work anymore.
Sent from my ADR6400L using Tapatalk
Wiping your system completely should fix it on cyanogen at least.
I was about to do that but wanted to make sure before I went to that extreme. Have so much crap loaded I'd hate to have to reinstall everything, even with titanium backup.
Sent from my ADR6400L using Tapatalk
Odd, the only time I've ever gotten that error is when I forget to shut off Green Power.
Your wifi keeps turning on when you try to tether. When this happens, are you near a wifi network that your phone can connect to?
Nope. Ended up wiping and starting from scratch. haven't restored everything yet but it works. Weird issue. Thanks though

Losing data connection

Hello all. I keep having issues with keeping mobile data working. Ill be surfing one minute then cut from data the next then i have to put it in airplane mode and take it back out for it to start working again. This happens quite a few times a day. I have tried making the new apn for internet as stated in one of the threads and it still did it. I switched to a wap.Cingular apn same thing happens. Im at wits end. This has happened on stock and several roms. I'm not in an lte area either. Can anyone help? Thanks.

What Radio are you running? I had similar issues on the UCLC5 radio, and they went away when I went back to the UCLC1 radio. The UCLC5 is paired with most ICS ROMs.
It could have been a bad flash of the Radio, because I'm now back on ICS with UCLC5 radio and I'm not experiencing any issues.
Good Luck!
I actually posted a thread about this a couple of weeks ago because the same thing was happening to me. Att just sent me a new sim card and that fixed the issue. But as of today it started happening again. I was on Seraphim rom coupled with the tablet mod and my data wasn't working. It would only work after turning on and off Airplane mode. Since then I flashed back to the unofficial Emily rom and haven't had an issue as of this morning.

I was Emily Saturday and didn't notice any issues that i can recall but i love alpha 2 with the tablet mode where do i get that radio and will it work with alpha 2? Thanks

Verizon's 4g data problem.

OK, I'm not sure if anyone one else has or is experiencing a data connection problem with Verizon's 4g toggling off and on. I know I "was" and this is my theory and it has actually worked for me but first let me start from beginning. I got new tbolt because having this issue, I rooted and install ROM and everything seem as it was fine until I decided to connect to myverizon app and as soon as I did I started experiencing the toggling off and on again. So I decided to un-install myverizon app and reflash radio again and sure enough everything fine now. Well like I said just my theory but I think if u log in to myverizon app its causing this data problem. Inconclusion if you un-install myverizon app and reflash radio you shouldn't have any more data connection problems.

Isn't it? It's like Verizon is trying to control usage. But like i said on post it worked for me, so i want to get a response from someone that has issue and tries it.

I constantly have to log in to My Verizon app. It's just part of how the ROM that im using works. I'm running Jellyblur 1.3 and have 4G data drops without even moving my phone on my desk at work. Considering I don't stay logged into My Verizon, I don't see how uninstalling it and reflashing my radio would make a difference. I love a good conspiracy theory though!

I'm saying don't use at all. Yes to update to see how much data u have used u have to constantly log in to update. What I'm saying is if u don't use at all don't even log in to myverizon. Give it a try... Delete myverizon don't re install flash radio again and tell me if your data connection is still dropping.

I did flash the .9 radio afterwards and noticed no drops now. I can't confirm the correlation between the drops and My Verizon. It could just strictly be that this radio version works better for me. Sorry, boss, but I like where your head's at!

For what it's worth, I never installed the My Verizon app on any of my ROMs and only had it while stock, which was a year ago. I still got major 4G connectivity issues a few months ago like so many others. Made the phone damn unusable at times.
Yeah I know it was a frustration for me. Have u tried new radios? .19 radios

I went radio happy a month ago and flashed them like they were ROMs. Tried probably 5 or 6 of them. I even tried different combinations of CDMA and LTE radios separately. No significant changes although the .9 or .19 radios seem to work equally well for me.

i was having this problem with juice defender and i switched to the beta and now im fine it may be a program like that causing your problems

Lost LTE

Hey guys I have been rooted for a while now but on Sunday I crack flashed a bunch of 4.2 roms and lost connection to 4g. I have replaced my sim card and re flashed the radios but I am now stumped. When I get home I will probably Odin back to stock but if you guys have any suggestions I would appreciate it.
Sent from my SCH-I605 using Tapatalk 2
you answered your own question...odin back to stock.
Just wanted to know if there was anything I could try in the mean time.
Sent from my SCH-I605 using Tapatalk 2
go into settings/more settings/mobile networks/network mode, then toggle lte/cdma and see if it brings 4g back up. If that don't work you can try a factory reset, still nothing then odin back to stock.
Yeah tried all of that. Looks like I have a date with Odin tonight.

Restored via odin and still no 4g. I'm at a loss. Could I have burned the 4g capabilities?
did you get a new sim from vzw? i know you said that you "replaced" it but was that with a new or used sim? also might want to power device off and make sure the sim is seated properly.
also are you getting 3g, 1x, or any data at all?
I finally got it guys thanks.
Sent from my SCH-I605 using Tapatalk 2
how did u fix it?
After all of that fighting the system, changing the sim, reloading stock the sim holder is sort of wide and the spring forces it just a bit off of the contacts I adjusted it just a bit rebooted and got 4g back. Always check the stupid things that it could be first. Lesson learned for the 10th time. Though I checked it multiple times before resorting to a system restore so who knows what caused it.
Always check outside before working your way in!

Interesting. .. Did you get a replacement? Reminds me of when my girlfriend tried the dna... She would drop it or tap the phone and the sim card would disappear from the phone lol.

I tried that, I tried everything. Even flashing a new firmware, non worked. I went to a local store, and he also flashed a firmware for me and he said the WiFi part itself isn't working, so I will have to pay about 110$ to fix it. I don't know, it was working perfectly, I went to the bathroom and then went back to chat with my friends and found it off. I really have no idea why this happened.
Anyways, thanks for the help.
If you have android 4.2.2 xxufme3 on i9300..then change it because it has wifi problem..
