[Q] CM 7.0 wifi connects but doesn't work

Hi all, I'm running CM 7 stable with latest radio (7.15.35.16) and 2.6.32.17 kernel. I I wiped data, cache, and dalvik cache before flashing cm7, then the appropriate gapps. The problem has been ongoing with other cm 7 RCs, but doesn't happen in 6.1.1. I am able to connect to wifi networks, but I can't load or reload anything in any app. The icon stays white/gray on the status bar instead of turning green like the data network icon does to show it's fully working. Tried the android dev forums, but haven't found anything that fixes this. Any help would be much appreciated.
<strike>So I found a way for data to work while on wifi. I have to enable gps and have it lock on in google maps in order for the wifi to send and receive data instead of just being connected and doing nothing. Don't know much of the code stuff so if anyone can figure that one, be my guest!</strike>
Thanks to ilostchild for the fix in the last post. Pull 'tiwlan.ini' from cm6.1.1 and push it to cm7. Located in System>ETC>WIFI folder. Mount system before pulling and pushing files. Good luck!

I believe your kernel is geared for FROYO not Gingerbread. You might need to reflash the ROM and don't flash any "new" kernels as of yet. It may break your wifi.

This is the kernel that came with CM 7, unless I'm mistaken. But I'll try the re-flash option. Update later. Thanks for the suggestion.

You're right, i'm an idiot haha. Have you synced your google accounts to your phone yet? The green and grey signifies your connection to google servers.

I did. I did see the green and grey while on mobile network, but only grey when on wifi. Should I not let the phone restore everything once I reflash? I might try that and make sure every aspect of the google account syncs before attempting a wifi connect. Either way, I can always go back to cm 6.1 Thanks.

Try nightly 39, I read that was fixed in it. I didn't have the problem so I can't say if it was.

Tried it as well... No dice. I guess I'm one of the (un)lucky ones. Thanks, anyway.

get the tiwlan.ini from cm6.1.1 and push it in cm7
its in etc/wifi
the do a reboot and try to connect to that

This worked for me, thanks!

Would you be able to make a flashable zip with the stock wifi files? I've been having problems with CM6 and 7 wifi.
I don't think anyone has ever had a problem with the stock rom wifi. It would solve nearly anyone's problem.

The stock wifi files wont work with cm7, because cyanogenmod uses mostly generic drivers for things we dont have source for. Have you tried formatting the system in recovery? format everything except your sd card, reflash cm7, then add the twlan.ini from cm6. thats what worked for me, and i was one of those "unlucky ones."

Tried flashing this zip but didn't work. Just seemed to get an error and abort.

Reboot every 3 minutes+sim error

Hi, I've been a member here since 2008 and this is the first time I'm actually stuck with a problem.
I got my hands on a friends Note II GT N 7105 ( LTE intl version) and its been flashed 13 times. (He bought it from someone) Had adam kernel and wanam rom and reboots every 3 minutes even on standby. Also the IMEI disappears sometimes and appears on reboot. sim does not work at all. No calls.
I've installed paranoid android and its still reboots and sim doesn't work. There's some solutions to IMEI here on xda but I didn't come across any that had IMEI status as unknown and then to have it available again after a reboot or after i"fix permision". Plus the rebooting doesn't go away by flashing a different ROM. So I suspect something else is causing this problem.
What are my options here? Try going back to a stock ROM to fix this rebooting and hopefully fixes the sim in one go? If there's a chance I'll try that.
And here's a snapshot

well that would be the best choice as of now to go stock and see if the prob persist then definitely it would be a hardware issue just dwonload a firmware from sammobile the n7105 version
or give a try here as u must be having a custom recovery now http://forum.xda-developers.com/showthread.php?t=2228921

Sometimes it's related to the kernel (i had the same issue on an Nexus 4)
Flash a stock rom, and see if the problem persist

Thanks guys. that's reassuring. I'll try the stock.

Didn't work. Its not rebooting atleast. I read somewhere flashing the ROM specific to the country worked for someone with sim issue.

No Network Signal

Hi Everyone,
Facing a strange issue, after installing Virgin ROM (Pure google 4.3) I am not getting network on any other ROMS, tried several roms (Infamous 10, 8.6, AICP)...
However, if i come back to virgin tom, i get the network signal back
Going crazy as i cant try any other roms...

I'd Odin back to stock. Then root again. Then try a new rom

You need to flash a more compatible kernel to get the network working properly.
I read about this issue and some people say to disable and re-enable DATA
after reboot, same holds true for the wifi..
Check it out!

Tried it with no luck... Even flight mode toggle didn't work, cleared cache and dalvik too... No luck
Will try the Odin way, hope that works...

no signal after flashing rom

i have a samsung galaxy s3, ive been rooted for a long time and flashing roms all the time. well i flashed a rom just now and i have no signal, not sure if i burned out the radio (not sure if thats possible, but it also said to insert sim card while it was already inserted), but i dont understand how that would happen. the sim card works in another phone that im using now, so its not the sim card thats causing the issue. my carrier is at&t, and no signal showing, not data or cell (wifi still works, but thats a different story). has anyone experienced this and know how to fix it? im guessing modem flashing, but not entirely sure. can someone please point me in the right direction? Thanks in advance!

just a suggestion, but try rebooting your phone again. this happened to me before and i got freaked out but a reboot has fixed this on a few occasions. running a flashed rom just fine right now.

I believe you need to do a factory reset. Backup your data first!
Sent from my SGH-T999 using XDA Premium 4 mobile app

The first thing to troubleshoot you should do is flash back to a rooted stock rom and make sure the data is working there. If so this will rule out any sort of hardware problem. You didn't say whether or not you did but you can also try fully wiping the phone (dalvik/cache, system, and data), re-download the rom incase you had a bad one the first time and reflash. Other than that check that maybe check the apn settings.

Yup I ended up doing that last night..im back on the stock root injected rom. So im still rooted and network now works! So im glad. How would I flash a rom without losing the network this time?

Now that you have flashed back to stock a full wipe has been done in the process. At this point all you can do is flash it and see, but as i said i would redownload if you plan on using whatever rom it was you mentioned in the OP. I would also do a full nandroid backup to save the pain of using odin incase it doesn't work. I imagine the problem was with lingering files/fragments from multiple flashes that were causing the problem, in any case whatever the problem happened to be it was software related.

K will do. Its just weird because the md5 matched and everything..but I will for sure download the rom and gapps again. Thanks for the tips!

well, i finally got the service to work after flashing a rom. it still remains a mystery to me tho, i used to always use the illusion rom everyday, for months. i decide to flash the same exact one but no service, i download it a couple more times and still no service after flashing about 3 or 4 times. i tried a completely different rom and the service is active. i dont understand why and cant figure out what is so different this time hah. o well, im just glad its all working now even though its with a different rom. thanks for the help guys!

ok, im back =[
i was using the carbon rom with no problems, it was working great, but just a half hour ago i was listening to music and texting (i always do this), and then phone just turned off. I tried to reboot it but it wont! it always shuts off while booting. i made it to CWM, but it turns off while in CWM. i also made it to download mode, which led me to assume that the phone is not bricked, but it doesnt stay on download mode, it just turns off randomly. i figured maybe it was battery, so i tried another, and no change! does anyone know what the issue is? i cant figure out how to keep the phone ON, or why its not staying on.
btw, i got it to boot completely just once, and it was acting up still. any ideas? please help
Thanks in advance

What is the bootloader and baseband version on the phone? Which version of stock are you flashing?

In Odin uncheck reboot phone before you start, reboot manually and flash twice.
