[kernel][cm7]Wifi Test

This is a kernel I'm working on to improve on wifi. Specifically the Hidden SSID problem people are facing. If you guys could test it for me. Give me some feedback. I still have an aria, just not my primary phone.
Install via clockwork over an existing cyanogenmod 7 installation.
Also make sure to wipe cache / dalvik

I will try this at home tonight.
Thanks for doing this.
But I would really like WiFi to just find my network after being out of range. Right now I need to turn WiFi off and then on to reestablish the connection.

+1 this is the only issue I have too. Once you go to another location where there are known AP's it will not connect to them without toggling wifi on/off. Have you addressed this in this kernel at all?
Thanks

I had no wifi auto-connect after booting. I had to toggle wifi off/on twice to get it to connect. Same thing after another reboot. Gonna have to flash the original kernel it seems. Thanks for the continued interest in this device BTW.

Try wiping caches and dalvik

I had the same problem - wouldn't connect without a toggle off/on/off/on.
I'll try wiping the cache and dalvik, and try it again.
Edit: wiping caches and dalvik, then reflashing the new kernal resulted in an HTC White Screen.
Still waiting...(it's been something like 10 minutes).
good think I did a nandroid BU...

Ok 2 reboots later and it is now dexopting. Looks like clockwork does not wipe dalvik if it is on sd-ext. I had to do it manually from the shell.
I had to do 3 off/on cycles to get it to connect to my network. I am broadcasting the SSID and it is WPA2-personal AES. It would connect automatically after reboot before, but not connect to a different network automatically without toggling on/off.
Edit: I have to do 3 off/on cycles now to connect after a reboot.

I'm restoring my backup. It looks like this isn't working for non-hidden networks.
It's odd - this wasn't a problem with nightly 43, which I still maintain is the best nightly published. WiFi re-connected without any issues in that build. Hidden SSIDs were never working in any CM7. CM6 - no problems.
I'm hoping this is something that is unique to 2.3, and not the CM7 build itself.

build #21 isnt pickign up my USB connection :S?

Doesn't find any of my broadcasted WiFi networks.

[Q] Wi-Fi issues on all CM9 ROMS

Hey guys!
I have looked up this issue, but everyone seems to have it then they reboot and everything is fine!
I flashed the CM9 - HellsFire, Eaglesblood, and the one released by CM_Arcee.....
Problem = When I turn on my wi-fi it gets stuck saying "Turning Wi-Fi On...." and just stays there. When I back out of the menu, and go back into the WIFI, it doesn't show the Turning Wi-Fi On..... but it doesn't show any wireless hotspots.
I tried flashing the kernel from Rootzwiki - the latest one thats made for CM9... and to no avail.
I tried...... anyone have any suggestions?

it's a known issue. Wifi calling does not work on ICS, and if it does, it's failing during calls. Hope time will heal this.
If wifi calling is essential for you, i recommend Eaglesblood GB 2.3 rom.

Did you wipe data, cache, dalvik, and system before flashing? If you're the only one having this problem then it's user error.

He didn't ask for wifi calling, just wifi. There are two 2.3 GB Eaglesblood ROMs, I think the one you're referring to is the 2.3.7 one though.

I tried wiping data, cache, dalvik, but I have never tried wiping system.... I will see if that fixes it.
EDIT
I tried wiping system, and then fixing permission afterwards, still no luck! I guess I will have to go back to CM7, and see if my wireless works there.

[Q] No Wi-Fi or bluetooth?

After restoring to stock with a Heimdall one-click (KJ1), my Bluetooth and Wi-fi have stopped working. About phone shows that their MAC addresses aren't known and turning on Wi-fi gives me an error (the box just says "Error"). The cell radio and data works fine.
Is there any way to fix it or is it a hardware problem?j

Is your IMEI correct? Don't post it here but does it correspond to what it says under your battery?

It does match the sticker.

Still not working, I'm afraid. I tried flashing with and without bootloaders—both yield the same result. Wi-fi won't turn on and BT & Wi-fi MAC addresses are shown as Unavailable under About phone.
Strangely enough (while backing up my ESN) I noticed there's a file named bt_addr.txt in the /efs folder that has the Bluetooth MAC in it (8C:71:F8:XX:XX:XX - the vendor prefix is the correct one for Samsung). Really weird.
Any ideas?

I wonder if the 10-15 minute battery pull would help? I know some have said it helped them when their IMEI seemed to be wiped out; it may be worth a shot here.

Did it and the problem still persists. Is it a lost cause by now?

One solution to Android Wifi "Error" or "Turning on..." - XDA Thread
[MOD] GB Wifi improvement! [CWM Flashable Added!] - GS4G thread (some reported improvements on KJ6.
[Odin/CWM] Modems (10/29/2011 added KJ6 modem) - Not 100% sure but I think WiFi is controlled by the modem - try a different one.
Have you done a factory reset?

Ive been having a problem with my bluetooth not working properly. It wont connect unless I attempt after restarting the phone. That thread suggests it is because of low memory, it makes sense. But My question is does the kernel affect this?

wifi problem in 4.1.1 OTA

There is a wired problem on my nexus s after updated to 4.1.1 OTA(stock).
Wifi is working fine after boot, but after i turn it off for a long time, it just can't be turned on, stuck at Obtaining IP Address.
The encrypt mode of my router is WPA-PSK, DHCP on.
Normally I restart the system to fix it... now that I try to set wifi to static IP rather dhcp after the problem happens again, and it is connected right away. I couldn't figure it out why the dhcp is working after boot but failed after I shut the wifi down for a long time? and when I can't obtaining ip address, i go into the router and found that the router already give the phone a ip...
Is anyone else encountered the same problem? Is there a way to fix it permanently? I don't want to set the static ip every time when i get out and use other access point...
and the phone's wifi is always working fine on this router, same settings, so it shouldn't be the router's problem...
P.S this problem happens on legolas93's aosp version and previews SDK ported version(one with SP4), i thought i could be the bug of their rom but this even happened in the official rom..

I'm not sure why you're getting a WiFi problem. I'm running an official ROM and everything seems to be working perfectly. Did you wipe data/factory reset and format /system /cache /boot /sdcard? This completely cleans the phone out so when you install a new ROM, its like that's the only ROM that's that's ever been on the phone.

I'm sure i did the full wipe and flashed the official rom of 4.0.3, ota to 4.0.4, installed the official 114mb ota pack of 4.1.1.
The wifi problem only happens when it's turned off for a long time like more than an hour and on a WPA-PSK encrypted router.

I had this same problem when running stock GB that came with the phone. It seems to be a problem with Android in general, not just that ROM. I used an app called Wifi Fixer (play.google[DOT]com/store/apps/details?id=org.wahtod.wififixer&hl=en I'm new ) in the play store to work around it. It doesn't fix it but it detects any issues with a wifi connection and resolves it.
That whole issue is a pain in the rear. The only time I completely fixed it was when I switched to a new ROM.

Wifi won't work on ICS, only on HC - Help needed

Hello all I hope you can help me with this...
I'm having the strangest issue with my P6200L... Everything was working fine a couple of days ago... I was using latest CM9 by aorth here, browsing the web and everything when suddenly.... Wifi disconnected and never reconnected again...
The symptoms are:
- displays all available networks in range
- if I force to connect, all networks disappear and saved connections are "not in range"
- if I turn off/on again it displays all networks in range again, saved ones are "disabled", if I force connect it repeats the cycle.
I tried factory reset dozens of times. Didn't work.
I tried flashing CM9 again (with this and another patch I found on the thread (forgot where it is)) dozens of times. Didn't work.
I tried flashing official ICS (Open Austria) dozens of time. Didn't work.
Needless to say, I did data wipe/factory reset/format cache/clear dalvik twice between each flash.
And then I flashed stock Honeycomb. It worked. Wifi connected! All was fine!
Marvelous! Or so it seemed...
Now that I got it working again, I want to upgrade to ICS, so I flashed ICS Open Austria. Wifi stopped working.
"Ohh well", I thought, "let's try everything again"
Flashed stock Honeycomb again. Working.
Flashed CM9 + patch. Stopped working.
Flashed ICS Open Austria. Still not working.
Flashed stock Honeycomb yet again. Working.
Flashed ICS Open Austria. Not working.
Flashed stock Honeycomb. Working.
My conclusion: Wifi works only on stock 3.2.
Why? I have absolutely no idea whatsoever.
I've tried every possible combination of flashing and wiping data (except from stock ICS recovery, as I have one of those bad chips and I'm afraid of the brick bug)
Is there anything else left to try? Maybe copying some system files over from stock Honeycomb to an ICS firmware?
I'm really getting desperate here and I've run out of options. I'm hoping the community here on XDA helps me solve this mystery.
It is similiar to this bug here, but although the user there fixed it by several wipes/flashes, apparently I'm not having the same luck.

Hahahaha I'm 100% sure this is NOT the issue here
Wifi networks keep dissapearing when I try to connect. I have tried in 3 different routers with different encryption settings, so I'm sure this is not on my end.

Could be that you flash and incorrect firmware, maybe for the p6210 tab?
Sorry, I'm just guessing , I don't know what could be the problem.

No problem about that, we're all guessing
But no, I'm sure it's for the P6200 because it worked the first time I flashed. If it was for the P6210 my tab wouldn't even boot, partition layout is different...

I'm having this kind of issue aswell. Wifi is doin' fine with HC 'til flashed it to ICS. Damn, I really hope someone could help us regards with this issue. I also tried Wifi fixer, it helps but not that enough. 'Cause it connects me to my wifi but after a minute or two. It'll disconnect and reconnect. This is happening again and again. And it's kinda annoying when watching video on youtube or surfing the net. Well, just sharing my issue.

Yeah, I know how it's like... I reverted back to ICS while there isn't a fix... It's weird because it also happens on official ICS from Samsung, which it shouldn't

guys, I had the identical problem with wifi on ics. I returned to the hc and wifi worked. Then again the ics and did not work. Wipe cache, Dalvik, data, everything I tried several times and no results . Then I installed wifi fixer and it was a little better, over *# 94 349 # tablet began work with the occasional stop. a couple of times I rebooted it. and after one reboot started to work normally. I know that I m not helped, but it is my experience.

Are you talking about this app? I've tried that, but the only thing it did was to keep disabling/enabling the wifi... Several reboots later, same results... I'm glad it worked for you, but so far I'm not in luck

OK, I got some progress.... But it's still bad, keeps disconnecting... Here's what I've done...
I flashed CM9 with wifi patch and tried the app above. Restarted, no luck. Still didn't work.
I removed my SIM card, restarted in CM9, and Wifi worked! If I put it back in, wifi stops working.
I tried changing country codes with the app above, lost 3G SIM card connectivity. No wifi and no 3G, I though I f***ed up everything.
ODINed back to stock Honeycomb. Got a "no SIM card" error. But wifi worked.
Restarted several times, tried changing country codes several times, still got the "no SIM card" error.
After several attempts by removing/inserting the SIM card and restarting I got it working, finally.
Tried flashing ICS Open Austria. Both Wifi and 3G works!!! However wifi keeps disconnecting every 40 seconds or so.
Tried Wifi Fixer from Market, but all it does is monitor when wifi disconnects and then resets it. It connects again, but 40 seconds later it disconnects again, thus repeating the cycle.
It's still not usable, but it is some progress. I'm afraid to factory reset in official ICS because of brick bug, but I'm willing to do some more steps if anyone got some more ideas
THANK YOU very much for your response petrenj! We're getting somewhere here! :good:

Unfortunately I'm experiencing the same problem as yours. I have 3 tabs and all of them exhibits the problem in ICS. Wifi seems a lot more stable in honeycomb. I already tried xxlpl and xxlpn with/without wifi fix from aorths cm9. I'm also experiencing force reboots when I disable and enable wifi for sometime.

How odd... It's weird that some people have this issue while others don't... Also, I'm beggining to wonder if this is something that aorth or other dev can fix, seeing as it affects several different devices with ICS, and not only our tab. I don't think it's a hardware problem, because wifi works in Honeycomb...
So far, if we want to use wifi in our tabs we must remove the SIM card or just stick with Honeycomb... I've stopped using my tab for a while due to the constant data wipes/flashes and dedicated it to try to fix this issue... I really don't want to restore all my apps twice a day while switching between ICS and HC versions
Are there any P6210 users reading this? If yes, are you able to use wifi in your tab? As the P6210 doesn't have a slot for a SIM card, this shouldn't affect you, right?
Anyway, let's wait for aorth to be back from his trip and introduce this thread to him. He should be able to clarify something to us.
