Wifi problems - Samsung Epic 4G Touch

I have started having a wifi problem. Everything looks to be connected and working properly (ie. status shows wifi, wifi settings show connected to my router with IP address), but I can't access the internet. If I toggle airplane mode, it will work. It will work fine, but will stop working again after asleep for some unknown time. I am currently running EL26 modem with Calkulin ROM 2.7 with the original kernel. I suspect the modem. I can't pinpoint when the problem started, but I think it was after I started flashing modems from my OTA EK02. I have restored ROMs that I know worked and now have the same problem. I have reflashed EK02, EL13, and EL26 to no avail. I restored to my current setup and did factory reset, wipe cache, and wipe dalvik. no good. I would prefer to avoid, but next step is to go back to EK02 OTA and start over slowly and proceed forward. Any ideas?
Edit:
I have corrected my problem, but have no idea what the problem was. I odined back to EG30. I was prompted for the OTA and took it. I did one root and installed EK02 stock+CWM. Installed a couple of my key apps and backed up. Rebuilt my system a couple apps at a time. Got everything working in this stock as possible environment. Once I confirmed no problems including wifi, I backed up again. I then restored my Calk 2.7 rom. I have been running with no problems for a couple days. My conclusion is a bad modem flash. I flashed modems from Calkulin's and qbking's threads. I am leery of flashing modems, but at least I have a pretty easy way back. Before I forge forward, I am going to delete all my modem zips. What is the best source for modem zips?

[Q] Broken Wifi after Root

I rooted my Epic 4G Touch last night and now my wi-fi isnt working. (Everything else is working well and I get very nice benchmark scores) I will try to turn on wifi, and it looks like it turns on but then it shuts off by itself a couple seconds later. I've tried a couple different kernels(zedomax, lostkernel). Also, maybe this is a related issue, but I downloaded WiFi Tether and when I start it, a few errors show up in the log (configuring softap, starting softap, activating WiFi interface--all failed). Not sure where to go from here. Couldn't find anything helpful in any other forums. I did try installing the EL26 modem but that didnt fix the issue.
Any ideas?
Sometimes this happens going between the recompiled kernels and stock.
I would backup your data and start from scratch by ODIN flashing EG30 or EK02 (from my signature) and do a ##786# reset per the instructions in those posts.
Make sure your running the same kernel with the same build. ie EL13 ROM with EL13 Kernel

Couldn't I just wipe and then flash Calkulin's EL13 rom? or is flashing to stock different? Sorry, I'm new to all this.
You are welcome to try what you want. I like to start with pure stock and reset everything to see if that works, then slowly introduce changes.

Sprint - Lost data, can't get it back

I was running CM9 without any issues (CM9 kernel) and did a complete wipe and flashed the ACS AOSP 4.1.1, and all seemed well. At some point I lost 3G, then it picked up 1x... and that went back & forth for a while... then eventually both stopped connecting and now it won't come back at all.
I even restored my CM9 nandroid and I still don't have data.
I didn't flash anything but the ROM and the gapps linked in the ACS thread, and like I said everything was fine for a bit.
Any ideas? Voice works, but no data.
I updated Profile & PRL with WiFi on, both said successful, but when I turn WiFi off the data connection doesn't happen. Yes, Mobile Data is turned on, and I've tried all of the different settings.
EDIT: I even flashed CM9 back over top of itself... nada. Next up... full wipe and fresh CM9 flash again... /sigh ***WAIT*** That fixed it...

[Q] CM10 alpha 4.4 Nandroid backup fail

I tried to back up with the tar option within clockworkmod, but the phone reboots during the back up process. Anyone else seeing this?
I nandroided a backup set as well. The one I performed yesterday actually reads with a time/date of 0:00:00 on 1/1/0000 and is unusable; phone resets when attempting the restore. A backup made on 8/24 is fine.
So could just be something w/ the rom, or with the rom + JB. Which JB are you running?
I'm on PhantomPhreak53's latest alpha (4.4). I didn't have issues with any of the previous versions. It was strange I tried creating a backup yesterday (8/28) it created a folder that was dated (8/29).
Hmm, odd.. the date on my restore was really odd in that it showed 0000. It actually did give me a partial image, but not complete.
I don't recall which build I'm on, version shows 20-20120822 unofficial d 710.
Will be nice when this is complete and great and not having a) the airplane mode issue, b) volume / voicemail issue, and c) horrid battery life. Yeah yeah, I know roms aren't necessarily responsible for battery life, but I figure if its sitting doing nothing for an hour, it shouldn't drop 15% of my battery.
I just tried backing it and rebooted while backing up data. The folder has the right date now (2012-08-29.19.40.57), but still incomplete.
I just want to back up, restore my GB room to update prl and profile. I just updated my modem to FH23, hoping it'll cure my slow 4G speed. right now 4G is benching slower than 3G.
Hmm, this may be a lame work around, but try this.
install AppBak, create a 'backup' of your apps (it's just a list of them with an easy way to reinstall one by one)
remove everything you can that is a regular installed app, then try running your nandroid backup.
I ended up flashing 4.3 and create a backup successfully. I updated prl/profile then restored back 4.3. Then updated to 4.4. I didn't make any difference in my 4G speed though.
Good it worked out.
I'm still working on trying to figure out how to restore back to an CM with ICS, so I can triangleaway and update to JB again. Ugh.
They posted that this is a known issue with the backup/restore through recovery best bet is to mobile Odin back to el26 do a backup then Odin restore the stock kernel for cm10 then restart should work

[Q] Weird GPS problem. What happened?

Yesterday my gps wasnt working at all. It would not lock on no matter what I did. I was on a custom rom and I tried wiping my data/cache, reinstalling maps (just for giggles), and a multitude apps from the market that help deal with gps problems (gps fix, gps status, toolbox, etc).
When all this didn't work I decided to odin back to the last official JB update and still no gps. On a whim I decided to odin back to an ICS firmware and that made my gps work. I have no idea but it did. I then odin to UVDLJC, installed TWRP's most recent and restored my backup of the custom rom I was using in the first place and gps now worked.
While I'm happy as heck that my gps is now working and that it was not a hardware issue I'm extremely curious what happened.
I have flashed many roms lately and I cannot think what a custom rom can do to gps to hose it or if it was just one of those things. I would of thought that when I originally did an odin to UVDLJC that would fix the issue but that didn't. Whatever the flash to ICS did fixed it but what in the heck could that of been?
I figure if I can find out or get an idea what happened then I can steer away from flashing certain roms, or just be prepared that flashing any roms at all can make this happen again.
Same here.
Hello, ddcoh.
I am currently having the same issue you had with GPS not working. I've tried everything from trying tedious Play store apps to trying many different roms and kernels (clean installing every time) to completely reverting back to stock including using TriangleAway in case that did any help. Nothing worked. I have been thinking about going back to ICS to see if that worked but the last time I tried to downgrade from 4.1.1 to 4.0.4 I ended up soft bricking my phone even though I followed the steps word for word.
Can you tell how you went about downgrading to ICS and then back to JB, please? I use my GPS a lot and I would hate to find out it's a hardware issue.
Typically, it's been when people are going from 4.2 to 4.1.

Well I used odin to flash an T999_UVALEM which was a prerooted ICS rom. After booting it up I checked to see if GPS was working and it was.
I then used odin again to flash T999_UVDLJA which is a JB rom and booted it up also and saw that gps was working. Then I just restored a backup of a room I had been using and GPS still worked.
I've been out of town and noticed that after flashing a few roms that gps wasn't working so instead of doing all the above stuff I just flashed a cm10 rom. I believe I either used a cm10 nightly (or maybe 10.1, memory is hazy) or LiquidRom and that got the GPS working by just doing that. Not sure if that will work for you but you could always backup your setup using TWRP's latest and then flashing a cm10 rom and seeing if gps is working and if that fixes it then you could then just reboot and restore the rom you are currently on and that might fix your gps for you.

[Q] Moble data works with stock rom, but not custom

I'm having a lot of trouble with my S2 right now. I've been running CM10 since I got it with no trouble at all. I updated to 11 when it came out, again with no problems. Basically what happened is I flashed the stock ROM so I could use the video camera, then just restored back to CM through recovery when I was done. I did that two or three times, then suddenly I have no mobile data on any custom ROM, OR on the stock ROM I made a backup for. Voice and text works fine, just no data, either 3G or 4G.
I eventually un-rooted and went completely back to stock, and that got data working. I rooted and got recovery installed, and everything's still working fine. But, no matter if I try to install Cyanogen fresh, or try to restore a backup, I don't get mobile data. If I restore a backup of the last stock ROM, data works fine. From inside the stock rom, I did a master reset and updated PRL and profile.
Does anyone have a clue as to what I'm doing wrong?
Okay, I noticed that my MEID and some other parameters were 'unknown', which according to Google can mean a bad modem. So I flashed a new one, and all is well.
