[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.

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."

Strange issue with Wi-Fi on android

Hi all,
I know there are loads of wifi post on here and I have searched and tried all updates and whatnot.
Initially when I dual booted my kaiser to android it kept coming up with an error on the wifi and just wouldn't start. I have put the update on that is meant to fix it and it now starts the wifi, but it just wont search for my wifi!?
If I enter it manually it just comes up with "Not in range"
Has anyone else had this issue?
Thanks,
Doomie

Thanks for that, just grabbed it, installed it and now it just sits scanning and still will not find any wi-fi.

change your kernel or radio version witch android version you use???

I have tried quite a few. The one I have just tried is "Scoot CyanogenMod 6.1.2 RLS6". All of them are doing exactly the same, its just making no sense.

Almost sounds like a bad radio install. I have had "0" problems with wifi using radio 1.70.19.09 OR 1.70.09.01.
Your results may vary as I've seen people using the 1.65 radio roms with no issues as well.
With dual-boot, I'm not too sure that WinMo isn't trying to control your wifi independently of Android. I have no experience in any dual-boot situations as I could never get Haret to work correctly, if at all.
I think I remember someone mentioning that you have to make sure the wifi is either on or off in WinMo before starting Haret. If someone has clarification on this, I'm sure the poster would appreciate feedback.

[Q] Crazy Johns/Vodafone APN settings???

Hi Everyone,
My Phone:
Lt15i
Baseband 70
Stock kernel with CWM
Arconium ICS
My Problem:
After going to a custom rom and kernel from a complete stock setup I cannot get a data conection on my phone. All other features work perfectly (Call, sms, wifi etc) just no 3g/2g data connection, or icon in the status bar. the Settings menu indicates it is turned on.
I have exhausted all available options regarding kernel/rom troubleshooting including a complete reinstall on the above rom/kernel. I also experienced this problem with other roms and kernels.
During setup I follow the setup app and download the apn settings for Crazy Johns (my carrier) and they report as being installed.
My question:
If anyone who is using Crazy Johns currently and has it working could please post their apn settings (text or screen shot whatever is easier) so I can compare these to mine and change as necessary.
Any and all suggestions for fixing this are welcome.

Yeah, tried getting it sent to me, entering it in manually, even tried entering various variations of it I had found on the net. Still no connection.
Everything worked perfectly when it was stock, and when i first flashed a new rom onto the phone (arconium 8.2 i think) it worked then too. but every rom since it hasn't.
I'm still quite new to this and my knowledge isnt too deep yet.
Could flashing roms or kernels effect the serial numbers of my phone or something and now my carrier doesn't recognize my phone?
I do still receive calls and sms...
It's got me beat!

Hmmm I think you phone is fine must be just the settings.
What does it say? Any errors? Can you grab a log too see if it says something there. Check my Sig for how to get logs etc.

Well props to you, you were right in suggesting it was settings related. I tried a different sim card from a different carrier and after following the setup procedure I had a 3g data connection. This of course means the problem lies with my sim card/carrier settings and not the rom or kernel.

[Q] I'm Dumb -- Help me get my radio back ( SOLVED )

I was playing around with the nightly build of CM10.1, and my radio stopped working. I flashed what I thought was the stock ROM back with Odin, but then I started receiving an, "Insert SIM Card" message whenever I tried to enable Mobile Data. So I flashed another one I found online. Still, with no luck (though the error was gone), I tried some radios. A dozen radios later, and I can get 3G data -- but still no calls or texts. I've been updating the PRL non-stop, still no luck (except when I'm roaming.)
I'm guessing the problem has to do with the many many files I have in /system/etc/firmware
Is there anyway I can get my radio back to stock?
Thanks!

you need a full odin flash with repartition. do not do this till you know for sure you have the right files to use. you can screw **** up with odin pretty damn quick. lemme search and ill see if i can find the right stuff for you.
EDIT:
I am downloading the files you will need to flash in odin. I want to see that they are indeed the correct ones for you to use. If you need help i can remote connect to your pc and help you out.
22 mins left on the DL and then ill be back

first rule of posting on any forum, "no question is dumb"
Rule number 2 " always ask if there is something you need fixed or need help with"
dont worry youre not dumb. though i may not be able to help you, the person above me hopefully will.

Quick answer from my own findings, the original stock ROM had a bug that doesn't allow it to see the SIM properly, but if you patch it (settings, update - or something like that), it will fix it (there will likely be a few rounds of updates).

The ROMs at Sumsung-Updates.com seem to be trustworthy. Are they?
Anyway, I finally got the issued resolved. It wasn't a radio problem that was blocking me, it was a badly linked Google Voice account. Sprint killed it, and now everything's OK (though I signed up again ^_^)

I had the same problem with the sim card thing...linked it to my wifi and it downloaded like 15 updates and then finally started working normally...probably incorrect stock rom or seriously old...got the one from samsung-updates and that works flawlessly

Radio issues with 4.2 Roms

Hi all, I am again posting about having radio issues. (NO T-Mobile signal) Any 4.2 Rom I try to install, I am unable to obtain phone service. (signal)
Here is what I did:
1. Start from scratch, total erased phone and sd card and micro card.
2. Odin flash stock Rom and Odin flash latest TWRP
3. Copy Rom to SD card and flash. (flash is fine)
4. No signal, flashed newest UVM6 radio, all kind of wipes.
My phone is SGH-T989 T-Mobile. I even changed the APN, but still only pick up AT&T which still having no signal bars. I tried flashing all radios available with no help at all. I am able to use certain 4.1.2 Roms such as Infamous 3. I even tried different kernels, different wipes and just can not get any T-Mobile signal service. I have tried searching for any and all radio issues for this phone. NOTHING works for me. Can anyone or does anyone have same problem that came up with a solution to get a signal for T-Mobile for these Roms? I am currently using the Infamous 3 Rom using Arc kernel. Actually the only other Rom I can use it the stock deodexed rooted base. Very frustrated not being able to use these great looking Roms, HELP please! Thanks for any information or solution. BTW, I have tried everthing and every type of wipe to no avail.

do you still have your IMEI or does it shows blank and unknown ??

I am having the same issue. It does show my imei # though. How do I fix this?

Oh boy.....again.
K....here is about everything. If none of this is your problem, since you say you've checked everything....and yes, I have read your other thread....in which you repeatedly say you tried everything, then you have a hardware issue, or are simply doing something wrong and telling us you did it right.
Not getting a signal.....
- not using latest T-Mobile or Telus radio. Maybe you flashed it, but is it actually showing as that radio in settings??
- APN settings are wrong or don't exist. Lets pause here. You said you checked apn and only pick up at&t. Or am I misreading that. If you don't have the correct T-Mobile apn settings, then you wont get a signal or data. Period. This has to be correct before bothering with anything else. You said you checked. Against what?? I've seen plenty of apn settings when Googling it, some simply don't work. Maybe they are old settings, wrong phone, whatever. I'm Telus, so can't help you with the settings for T-Mobile.
- what has already been posted above needs to be correct.
- maybe radio file you flashed was wrong one or corrupt. Perhaps try the Telus one. Should work too. Since T-Mobile radio works on Telus.
- restoring any system data after a flash? Huge no no.
- wrong mobile band selected?
- and a possibility .....simply no signal where you are. Or it's a weak signal, and your assuming it doesn't work?? Ignore this if you have a very strong signal usually where you live. 4.1.2 to 4.2.2 shouldn't affect signal much if any.
Anyway.....that's about all there is to it if you are CLEAN flashing roms and following instructions to the letter. I am confident you will say all the above is good....and if so....I am afraid you will probably find no answers like your other thread. Meaning you have an extremely rare issue. Or a wierd hardware issue, sim card maybe....tho before you dismissed that as a cause. Another possibility is that you aren't correct when you say apn is fine, or the radio you flashed is fine. Not accusing you of misleading anyone, just saying perhaps you are innocently wrong when you tell us this or that is fine when it is not.. I've done tech support.....happens all the time! !!
So, good luck. Hope you find a solution ......tho this is your second thread on same issue....so you may have some rare issue....and may be boned.

He's got something wrong for sure. Or he's got a strange phone that won't work with 4.2. And I doubt that very much.
He's got wrong radio, or wrong or missing APN settings.

Thanks for helping and I think your right about being boned or hardware issue. I have tried different downloads of radios, both Telius and Tmobile and copied APN settings from working stock Rom. Maybe bad Sim, anyway I will have to stay with what I have until I get new phone, which is soon. Thanks again!

Stumbled across this. I've never heard of this particular issue before, but sure sounds the same as your issue. Try this fix if you haven't already.
Everything below is copied from another thread......
i had this problem with slim too. i thought something went wrong with my phone or my area. but nope. what you need to do is go to mikeyman777 cm10.1 thread and find the uvmc6 tar file, then use odin to flash it. apparently just flashing the newest radio with twrp isn't enough because it's missing some files or something like that lol.
anyways i haven't had signal problems since flashing radio tar file. i've lost signal like once. before i was losing it everyday. hope this helps.
