Wi-fi broken after root.

Hey guys. I just rooted my E4GT and didn't install the kies application first. My phone is rooted and everything seems to be functioning except for the wi-fi. Whenever I go to turn on the wi-fi, it turns on, scans for a network and then the wi-fi turns off again. Am I boned? PLEASE HELP!

epic 4g wifi broke
Same for me, after Rooting with oden the wifi searches and then turns off, any help?

I'm sorry you're having the same issue. I haven't found any solutions yet. Would you please keep me in the loop if you find one? Isn't there an IRC channel where some of these guys go and help answer questions?

Something went wrong with your flash. No worries tho you just got to go back to stock and root again. Are you familiar with Titanium Backup? If you are back up all your user apps + data. Then ODIN back to factory restore. Then auto-root with this method. Lastly restore all your apps with titanium

this happened to me but i fixed it easily
forget your wifi
connect again with password and repeat it again until it works maybe 3 times

This is good advice. Do what Kogama recommends and you should be up and running. If not, hit the "HowTo's" link in my signature and follow the steps for a Hands Free Reset. Fast. Simple. Effective. Probably a good idea to do one anyway when you make major changes such as rooting or ROM hopping.

after i rebooted the wifi stopped working and i cant get it work again actually..where is this hands free reset i cant find it only the activation which I also did again

Just_s and Kogama - That method did not work for me. By time I had typed in the WPA key, the wi-fi antennae had already shut itself off.
BUT
KelvCast - your method totally worked. Is it me or does this antennae get piss poor signal strength? But I thank you VERY much for helping me. I'm all good to go. Now on to trying to figure out my write permissions on my Kindle Fire =/

for kelvcast's way you have to completely change your modem back too right? ....damn
im running a completely different rom btw...

"Hands free"is the same as "activation". Sorry that didn't work for you. The only time I had an issue with WiFi, "forgetting" the connection and then logging in fresh was what worked for me. Any other data/ connection issues I've had have been resolved via the hands free reset.
As far as your other question, you don't need to change modems, but it won't hurt if you do.

I have the same problem as OP. Rooted using the Zerg exploit, running stock ROM. When you turn the Wifi on, it only gives you like 5-10s before it turns itself back off, also the MAC address field shows unavailable.
Assuming it's an issue with the root process. The odd thing is mine worked fine for over a week, and just randomly died today while trying to connect to wifi at school. Was going to reflash stock kernel with ODIN, and see if it effects it at all.

How do you forget your wifi?

Hated to do it, but had to flash stock ROM, just the kernel didn't do it.

I was having the same problems... flashing rogue kernel 1.3 fixed it perfectly for me. Hope it helps

My WiFi is working fine with the method I used. Rooted phone and everything.
Not sure if I will be keeping Sprint anyway.
Did a speed test on my moms old LG Verizon phone running at 600mhz. Compared it to my Sprint SGSII running at 1.2ghz dual core. On the LG, I get a little more that 1/2 a meg per second (which is decent in this area) as compared to .01 - .1 meg per second on my SGSII. So there is a BIG difference in speed. I know its not the phone, but the network. Going to do my due diligence and keep the sprint phone for at least another day. But if it goes as it is now, I will be going to a Verizon store Sunday and switching carriers again. Sprint doesnt seem to be better that TMO. Sunday is my 3rd day so if I return everything to sprint, I get a full refund.

Yeah it's hit or miss. In my neighborhood, my buddies with Verizon pull down 1/3-1/2 more bandwidth, but my phone works in any basement in the area and theirs doesn't, go figure. In the mid-town/downtown areas both carriers perform about the same around here (Omaha, NE).
Now if you're talking WiMax and LTE thats a different story altogether.
As for the Thread topic: I think I know what broke mine- I restored a bunch of apps using Appextractor, and think restoring the "Settings.apk" in the system section toasted it. I tried flashing a few different kernels to no avail (Did not try the rogue kernel, however).

Lost WiFi after rooting Epic 4G Touch
I have been fighting this problem for a week now, finally I installed clockwork mod following a youtube video titled (How to Install Clockworkmod on the Samsung Epic 4G Touch - Latest) sorry cant post link new user arent allowed to post links. my phone was already rooted. I now have my WiFi Back.
Hope This Helps

I have tried every method I have been able to find.....Still no wifi. I rooted via this guide (http://forum.xda-developers.com/showthread.php?t=1265429). After following that guide my wifi did not work. Just scans and then turns off. Does not even see any networks. I flashed the stock kernal. Still no wifi. I don't know what else to do. I am going to try a factory restore. If that doesn't work I might need to send my phone in.....This blows.

Factory data reset brought it back

BIG PROBLEMS, no 3G/4G mobile service since yesterday, tried EVERYTHING

Need some help here. I never usually need help, been modding everything possible on Android for years now. But can't figure this one out, getting worried.
Had my LTE Nexus since launch day. No issues like this before.
Been on all Team Kang AOKP toro ROM updates since release, always on the latest. Stock kernel. Was on build 20 since it came out.
Yesterday at work, had a few bugs from probably not data wiping from build 19, so I wiped it all and re-flashed 20 again. Restored Titanium and started re-setting things up, I believe these are the only things I did. I was at work where I would normally have minimal, but some, service.
Ever since around there, I have not once had a bit of 3G or 4G service. I have not seen the 3G logo for even an instant, only few, gray bars. Wifi works fine of course. It's possible I even lost service before wiping and re-flashing, but I can't recall or didn't notice.
I tried all the usual stuff, wiping everything again, re-flashed AOKP 20, re-flashed other/older ROMs, re-flashed latest radio, restored old Nandroid backups, pulled battery and sim card and put back/rebooted...NOTHING IS WORKING. Also, I have driven through several towns since yesterday so I know it's not a local outage. Also, other people with Verizon phones here have service fine.
I have basically torn the phone down software-wise and nothing has fixed the issue. I still have no service. Each time I re-flash a ROM, it always makes me go on Wifi when it wants me to sign into Google...it never picks up mobile service then or after.
The About>Status screen says:
Network: Verizon Wireless
Signal Strength: shows an actual number reading that changes
Service State: In Service
Roaming: Not roaming
Mobile network state: Disconnected
Please suggest things I can try, but I guaranteed I have already tried them. Can't understand or imagine what is causing this, because I did nothing different than I normally do.

Also, I posted this on Rootz as well, and many replies so far. Still no luck though.
If you have an idea I can try, maybe post there instead at this point for me?
Thanks guys in advance.

It seems a radio problem. Try to flash the stock ROM from Google.

Well I did go back to many random earlier, more stock custom ROMs in hopes of a fix, but nothing so far. I am currently back on the stock 4.0.2 ROM that is rooted and deodexed by Bigxie, but I guess I can go all the way back to stock 4.0.1 or 0.2. Will try now.

Went to Verizon and it looks like the sim card swap did it. The girl there was nice and did it without hesitation for me.
She showed me in her computer how under my family account, it wasn't even fully showing my device or something like that. Not sure if it wasn't there at all or if it just didn't show that I had a 4g phone activated on the account...but I'm sure it was related.
Sucks to have to get a swap and still don't know what caused it or if its related to flashing roms, but at least it works! No issues since...

It is possible, but unlikely and no reasonable explanation, that your sim somehow got affected doing all the flashing and stuff.

Won't Connect to 4G

So everything was fine on my Evo (running one of decks roms with a ICS theme) until the screen went out friday night. Saturday I took it in and it was repaired in about 2 hours (very impressed). In between I activated an old back up phone to get me by. When I picked up my Evo the tech had reactivated it and it was ready to go. But when I got to work I had no data. No internet service at all. Calls and Texts were fine, but nothing else. I made sure mobile data was checked, (couldn't update PRL cause of the AOSP rom), but I did a battery pull, rebooted, then I decided to nandroid back to a previous sense rom. Once I booted up still nothing. after about 2 hours all of a sudden I was getting emails, and voxer messages....I had data back!!! But when I tried 4G nothing happened (stays on obtaining IP). Hoping a newer stock based rom would help I flashed the new swag ON rom. Loving the rom...everything is great, but still no 4g. My last resort is to unroot and go back to sprint. I downloaded the wimaxx checker and it says I have my RSA keys so I know those are there. I'm sorry if this is a bit long winded, but I thought being as detailed as possible would help. Any suggestions would be great. The members here have helped me through lots of trouble shooting in the past.
Should also be noted that I attempted PRL update again with no luck, and I live in San Antonio which is a solid 4g area for me.

Good thinking with Wimax Checker - That's usually the first line of defense.
It sounds like because you cannot update PRL or Data Profile that there may have been an issue in the reactivation by the tech at the Sprint store. With that said, I know I'm in the Philadelphia region with good 4G but occasionally there will be a day or so of PRL/Profile update "outages" where I cannot update. I usually will verify with a family member's phone (also on Sprint). Perhaps try having someone you know in the area with Sprint and an android phone try a profile and/or PRL update to make sure it's not just the system being unresponsive.

Ok I will try that tonight and reply back. I had my g/f's evo running decks rom try her 4g and it worked perfectly so I know its my phone. I'll see if she can update. Either way is there some sort of combo pack I can flash for profile and prl??? I'm not too sure how that would work.

Here is the latest Radios-Wimax-PRI-NV Combo pack Click HERE

Ok I flashed an older Wimaxx since the one I had was up to date(did a check in TE). Once flashed and booted up still no 4g. Is it possible that this could be a hardware issue since everything else works? Like the actual antenna is busted? Just hard for me to think that since it was working fine before my screen went out. I always have 4g service at home and work. And my g/f's is working fine she has the evo and she has sprint.

How to fix Call Dropping ???

I've had this phone about a month, and I can't have a phone call longer than 15 minutes without the call dropping. It has nothing to do with my location, because I have an Evo and older Epic in the same house and neither of them have a signal problem.
I have tried multiple PRLs and modems, including EL29, EK02, and many of the newer ones like FD19, FD24, FD26, FE07, etc.
Some of the newer modems were terrible, in that once I got loss of signal it would stay that way and I'd have to reboot. With EL29 and EK02, the loss of signal appears for only a few seconds, but when that occurs during a call the call drops.

seems like a weird issue, and looks like you have explored software related issues. One thing you could try is a network reset and force the phone to re-activate on the network, you will need your MSL though. If your device is rooted then you can get it. once you have your msl, go to the dial pad and do ## 72786#, it will ask you for your msl and should reset, this just clears out your programming information and should force the device to go through hands free activation. Not sure if it will help, but I don't think it could hurt.

Tried that also, same problem.

You stated that you've changed prls and modems. Have you tried any different roms?
Sent from my SPH-D710 using XDA

I'm currently using Blazer 4.1 ROM.
One thing I've noticed, is if I turn off 3G data, then the Loss of Signal occurs a lot less often. Today I had a 40 minute call that didn't drop once I turned off 3G. Before I turned it off, I had 5 consecutive calls drop before they reached 20 minutes.
However, it's not a total fix, because I still get Loss of Signal from time to time with 3G off.

ever find a solution to this? this seemed to only appear when i went from a GB to a ICS rom.. but even after i flashed back to my GB rom/older modem, the problem is still there..

Ive had issues network related on mine. Certain roms well kernals mess with things that need left alone. Are you running one of the LOS kernals? I had constant issues with them. Try doing a full format then flash to stock unrooted eg30 then use ota up to ics. Then flash on. Ive fixed many issues with this method. IT seems when we flash flash flash it messes with it. But flashing back to true stock formated does seem to help

i'll try that, i do remember trying to flash back to stock ICS while trying to fix things and that did not help. i would have figured just restoring my old GB rom would fix things but seems the network issues were stuck.
Thanks

[Q] A bunch of questions in one???

All right I have a few question I figured I'd ask in one thread they pertain to one another I guess.
1. (blazer rom 4.0) So last night I flashed this rom because i have not given GB a chance everything went well flashed fine......but when I booted the phone everything came up but I had no service. not a empty signal display it had the circle with the slash through it no service. under about phone it said I had no number, no prl, no nothing. after doing a shutdown and restart service would come on periodically and the it would go back to what I had just mentioned.
2. (prl and profile update) so the whole reason I flashed I flashed back was to update my prl and profile. but for some reason I can not do either. for this one i just flashed back stock el29. It would say and show that I had a 3g signal but everytime I the instant I would hit update the signal would vanish and 5 seconds later i would get (error: no connection) thried this with 3g,4g,wifi no luck.
this also happen when I was talking to a sprint rep setting my epic up, it took an hour and half to get my phone updated, no bueno.
do we have prl zips for are phone? and where, if so?
and any help with the blazer rom would be great. From the little bit I messed with it, it was a very smooth and snappy rom.

There are no prl zips that IM AWARE of. I'm pretty sure there are none! Idk try to see if sprint repair can find something wrong with it! Or you can try to flash a different modem. Sorry about your issues
