Wifi won't connect on CM9 ICS roms - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

I'm trying to install a CM9 ICS Rom (specifically one of these builds) on my tab, I can install the Rom with no problems however my wifi won't connect. It will turn on and it can see the networks however when I touch one to try to connect to it it changes to say saved and doesn't connect. If I press and hold on the network I want to connect to and then touch connect the popup box disappears and nothing happens. Everything else seems to work it just won't connect to a wifi network. I have tried the builds from both 2/29 and 3/4 and have had the same problem on both. Any help would be greatly appreciated
I apologize if this has already been asked I tried searching the thread to no avail, and also tried asking this question in the development thread but got a message saying I couldn't not post there because I don't have ten post.
I have been using custom Roms on Android devices for several years and have never had any problems until now. Any help would be greatly appreciated.

have you tried wiping cache and dalvik cache in cwm? Or maybe a factory reset and try fixing permissions as well.
If that doesn't work, I'd re-download and flash the ROM again

I wiped both cache and dalvik cache before I flashed should I wipe them again after flashing? What does fixing permissions do? I've never used that before.

Some of them have a question about using a international sim… Infact i have the same question… i have flashed my phone with multiple different roms still i cant get my Vodafone sim to work majority of the times i get this error message “com.android.phone has stopped working” i am not sure if anyone has answer. But i would really appreciate if someone could help us with that error message. Thanks again
Clear catch,dalvik and fa Tory reset. Flash jokers 3.2 cm9 from and g apps. Let phone boot up to setup screen. Reboot into recovery, clear cache and dalvik, flash jokers 4.2.1 or 4.3 and reboot.
This worked for me.

MAC Address Unavailable after Flash

I am running a rooted TF201, and recently got NVFlash. I am on the latest Vicious ROM, and am a recent convert to TWRP. No matter the ROM that I flash, I get a "Turning WIFI On..." eternally, and when I go into settings the MAC Address is Unavailable. I have tried to flash CM10, EOS3, and CM9. All of them load clean, and I can tether off bluetooth, but I am unable to get a MAC Address to turn on the Wifi. I know this is not a hardware issue, as Wifi is working just fine on my Vicious nandroid. That is the only way I can use Wifi is on that specific backup. I have tried to wipe, and reload that ROM thinking my Prime just liked Vicious, but the Wifi was broken then as well. I have done a few Factory Resets, and wiped and flashed anything I can think of to try and fix it. Thank you very much in advance.

When you installed these roms, did you wipe cache, dalvik and factory reset? Most devs say to wipe all 3, if you did try androwook rom though its discontinued I have never had a wifi issue. Actually I am running eos 3 build 37 now and it works also. You didn't do any kernel switching did you?
Sorry, should have included that. I did wipe everything every time, and I haven't touched a kernel. I am lost as to what is happening. I am using TWRP 2.2.1.4

Did you run a checksum on your downloads to make sure they are complete? I don't think I have seen this issue in the forum other then the kernel being not quite right...
I think there is something (i did) wrong with nvflash.... i'm stuck with another mac-address http://forum.xda-developers.com/showthread.php?t=1812773
I hope some nvflash devs can look @ those wifi problems. I also saw warnings on xda forums using nvflash, because it can change mac, imei & serial.
Yes, i made sure the downloads were good. I made some backups, then I used this file

Placed a good fresh EOS3 ROM and GApps on my microSD, ran the wipe and Still didn't get a working Wifi. I am welcome to try any kernel option, see if it works.

I was able to get a clean fresh ROM to open and make a WIFI connection. After a full wipe, Virtuous Prime 9.4.2.28 v1 to load and work with no issues. I have a C2OK serial number, think that may be a reason I am having issues with other ROMs? Is it a way this particular ROM loads? I had tried other ICS ROMs, and I would have the same issue as JB ROMs, so I don't think it has anything to do with it. I got full function back, but am wondering why I can't load other ROMs.

Mine is a c1ok but i haven't seen anyone with a particular serial number have issues and I do read a lot of posts... full wipe should in theory get you where you want to go but you may have something else going on.. bad download, bad cable (this I have seen) the bad download sometimes ends in failure to flash at all.. had that tonight actually lol... re downloaded checksum.. all good now... I have had a few oddities going from one rom to another but a second flash sometimes clears it up.. never had issues with wifi unless there is something up with the kernel...
Come to think of it.... there were a few posts that said they required a double full wipe... it's an option if your willing to put in the time.. full wipe, adb push wipe file again... wipe then push rom.... if i was going to take that route, i'd push androwook rom I went from that to jb EOS and haven't had any issues....of course that means cache wipe, dalvik wipe and factory reset in between....
I tried what you said, I'm and using the wipe zip, I triple wiped, and then loaded Baked ROM 4.1 to see. Md5 check was done of course. I got wifi to turn on, but it will not find any networks. I have reset my modem/router, and restoring my old ROM wifi works and connects just fine. I am going to repeat the process with a different ROM to see if it may be that specific ROM.

I am confused too. I did the same, using the wipe zip, and between wipes I wiped dalvik. I wiped three times, just for good measure. I then flashed AndroWook Hairy Bean v1 and AndroWook Prime v2.6, not at the same time obviously. With each ROM, I was unable to see any wifi network on my TF. The wifi may turn on, may not, but it will not even show any network. I am at a complete loss. I am able to connect via a blue tooth connection to get Internet with both ROMs.

[Q] Wifi not working

Solved
Hello everyone
Since a few days ago my S2's Wifi is not working
h.ttp://i.imgur.com/ojDOm.png
The icon stays like this, pressing it does nothing. it happened 3 - 4 times before, usually, I'd just reboot it and that would do the trick (I google'd a bit and saw this is a common glitch when trying to turn wifi on), but not anymore, it refuses to turn on no matter what I do, rebooting, shutting down and restarting, it's stuck.
h.ttp://i.imgur.com/KeMxb.png
I can't Scan, add a network nor switch the toggle on/off because pressing them does nothing, So... I thought I should do backup and factory reset it, nope. still stuck.
What's wrong with it? Any ideas? The phone is a year old, running 4.0.3 Stock
Sorry about the dots in the URL's, can't post links yet.
Edit: Forgot to mention it started doing this since I got ICS, maybe I should try flashing it to see if that fixes it, I'm kinda reluctant though, since the factory reset didn't seem to do anything and I haven't done it before.

Do the steps below
- Boot to CWM recovery
- wipe cache partition
- wipe dalvik cache (under advanced)
- fix permissions (under advanced)
- reboot system now
The above steps will not make you lose some files and data
If that does not help, then flash another kernel
Since putting a custom kernel on my phone my bluetooth does exactly the same as what your wife is doing. Only way to turn it on is to reboot the phone whilst it is trying to turn on (ie whilst it is a shade of green)

you should be Ok its relativley straight forward
Well, Flashed in CWM Recovery and CM9, wiped cache, Dalvik cache and fixed permissions but the wifi is still not working... it's still stuck at "Turning Wi-Fi on"
I really have no idea about kernels and that stuff, I don't know how to flash 'em (unless it's the same as flashing CWM) or which one to get at all, since theres too many and I don't know what they do/know if they're compatible.
Flashing kernels are the same as flashing ROMs and modems..
There are 2 ways to flash kernels.. 1 is via odin (.tar file) and 2 is via CWM (.zip file)
Now, if your ROM is on JB then use a JB Kernel
If ICS = ICS Kernel
AOKP = AOKP Kernel
AOSP = AOSP Kernel
The thing with kernel is that you have to match it with the ROM's base..

Hm...Checked my phone 7 hours after flashing CM9 on it and suddenly the Wifi's back on
Any explanation for this? It doesn't make any sense, I didn't even touch the phone during that time and it fixed itself?
Edit: Thanks for clarifying that up saywhatt, since I already flashed if and thus, voided the warranty I might as well go ahead and try flashing a kernel to improve battery life and get into the scene.

No problem.
Perhaps the ROM was "settling"? Lol i dunno.. but i'm glad to hear you got it sorted out. You can revert back to complete stock if you have some serious problems and it is needed to be sent to the service center..
1 download triangle away to clear the binary count
2 flash stock firmware
Voila! U no longer have a void warranty

[Q] PACMAN ROM wifi stuck downloading

International Player 5,0 on PACMAN ROM wifi stuck on downloading status. Happened before and went away for no apparent reason and now is back to stay. Wifi was working fine, but now the playstore sticks on "downloading." Since wifi was working, and still is for other stuff, would using a different kernel help? Has anyone resolved this?
Sorry, noob not allowed to post reply to someone else in dev thread reporting this problem already.
I had the same problem. Found no solution. So I had to do a clean install wiping everything.
That worked, of course.

ya i would say that maybe boot into recovery, backup, wipe: dalvik cache, cache, factory reset, system. then go back and install the rom again and see of the issue persists.

Connections Problems

Hi. I'm running CM 10.2-20131014-NIGHTLY
I have been having a few issues with the phone recently.
My wi-fi doesn't work, I can't connect with the wi-fi of my house. Sometimes it will be stuck with obtining the ip adress, or says connecting but no luck.
I don't have bluetooth anymore, it says turning bluetooth on (the key is grey not blue).. and then goes back off. I had tried with the botton from the notification bar but it doesn't work either.
I don't have any network connection (3G, G, H, H+), the phone works fine with incoming/outgoing calls, sms but not internet.
I don't know what to do, I have been using this version from a long time and never had problems.
Go to recovery and wipe cache and dalvik cache in advance and reboot. Test it. If its not working wipe data and test. and if all else fails full wipe and reflash rom and gapps.

I have done the wipe cache and dalvik cache, didn't work.
I have done the wipe data, didn't work
I have been searching and I found that CWM keeps untouched the internal SD and keeps rom and kernel, so..
If in the worse case i have to go back to factory how can I do that?
I really don't want that...
The only ways to go back to default are to DL the firmware from sammobile and flash it with either....
PC Odin...
or
Mobile Odin....

What I want to know is if there is a way to fix those problems without having to get back to factory.
Well you could always try @hawkerpauls ROM and kernel nuke scripts and then re flash your ROM.......

kernel scripts?? Can you explain this, please?
What they do, as I understand it, is perform a 'deep' wipe of the intended partitions prior to flashing a ROM....which essentially allows you to 'clean flash'.........all the info you need can be found on the thread.....
http://forum.xda-developers.com/showthread.php?t=2100558
Edit....having read the thread, it looks like I was wrong.......looks like a KERNEL wipe script is not available......might still help to 'nuke' the other partitions though.....

Wi-Fi was working a few minutes ago but now back to not working.. In my phone appears the wifi of my home and says that the signal is excelent but when I press 'Connect' in my phone appears like the connection is poor and don't connect..
I was wondering if reinstalling CM would work..
Today I 'fixed' the 3g connection problem by changing some APN values, now I can use Whatsapp but I can't connect to internet.
First the following message appeared: ' authentication via the proxy server was unsuccessful'.
Rebooted the phone, now this message doesn't appear anymore but pages won't load, play store says 'Connection time out'..
Phone calls/sms working fine.
Any suggestions?
