Wifi doesn't enable anymore - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hi all,
I'm running custom roms for almost 1,5 years on this phone and never had any problem.
But since a few weeks, i cannot turn my wifi on anymore.
I usually use 3G, but once I need to download some larger files (updates for example) I sometimes enable wifi. As I don't use wifi that much, I can't really then when this problem started.
When I try to enable wifi (swiping off -> on) it goes to on but the button stays "grey". Once I exit the settings menu, and reopen it again, it shows "off" again for wifi.
Turning it on via another menu doesn't make any difference too.
I already updated my roms, but still no luck. Tried difference modems as well, but no luck.
Bluetooth works the way it should, so it's only related to wifi.
I already tried renaming the "/data/misc/wifi/wpa_suppliant.conf" file, but after a reboot the system doesn't even recreate that file.
Also took the battery out for some time, but that didn't any effect at all.
Anyone that has some ideas what could this problem?
Thanks!

Try another kernel. Try reflashing your ROM too. BTW it's not modem related.
Smack that thanks button If I helped!
Always make a nandroid backup before trying anything risky.

Thanks for you response!
Any kernel recommendations?
The phone is currently running AOSPA (Pananoid Android) 4-ALPHA, but without any difference when it comes to wifi.
Current kernel:
3.0.64-CM-g7fc3ce7

Go back to a stock rom and check. Wifi is kernel dependent.

Try unrooting? Maybe flash a new rom/modem/kernel. Use your resources
Take a look at your modem, i'm guess when you flashed in Odin you applied a kernel with a different modem. Happened to me when I rooted the wife's cappy after the AT&T 2.3.5 upgrade. Checked the modem and sure enough it was changed so i just flashed back the stock KK4 kernel and all was good. There's a thread in this section that covers it.
ok is there anyway i could get all the right stuff together that way this will be fixed?...or could someone give me like links to the stuff i need and help me?

You can find a list of i897 modems here: http://forum.xda-developers.com/showthread.php?t=1300843 (second post).
Download the zip, put it on your SD card, and flash it in CWM. You can also push them with Odin, just extract the modem.bin from the zip, put it in the phone slot in Odin, uncheck everything but autoreboot, and flash.
The list is oldish and doesn't have anything newer than KK1, but any of them should work. A quick search should turn up a KK4 flasher as well.
i didnt work

Your next bet would be to flash back to stock and start over. Something obviously went wrong along the way.

CM10 wi-fi issue

I guess everybody who flashed cm10 knows about this. Connecting to wi-fi takes a lot of tries to work, if at all. I managed to connect to my router at home, but it is super annoying to spend 20 minutes at work to reboot and change regional settings just to find out that it doesn't work at all.
Is there any solution to this? Have I done something wrong? Atm i'm running the latest nightly, but i also had the issue with the FXP 152.

Yes, its a well known issue. You could have asked in the cm10 discussion thread instead of starting a new thread here.
The trick is
1) Enable wifi, reboot
2) Search for network, reboot
3) Connect to network and enter password, reboot
4) This time do it all again and it will work.
So, the regional settings don't have anything to do with this issue?

[Q] disconnecting bluetooth

I have a problem with connected bluetooth devices.
I am using handsfree HF-210 in car for phone connection and Nokia BH-505 for phone and music connection while i am riding bike.
Currently I have installed CyanogenMod-7-20130608-UNOFFICIAL-cooper and both devices disconnecting and connecting again from time to time.
Especially when I am trying to listen to music it stops after several seconds, disconnects and reconnect. It is very annoying and it's almost impossible to listen to.
Sometimes restart change severals seconds into several minutes but problem is still there.
Previous roms i have installed (Giogel port v3 and Glsmt 2.1) has no problem with bluetooth
Any idea?
try flashing another version of CM or give a factory reset hope this works. pls hit thanx if helpd!
Maybe it had something to do with the android version of your rom. I experienced similar problems with my ace on 2.3.6 . They were gone with 2.3.7 (and above).
Hope this helps,

number disappeared when i complete it and nothing happened. No menu, no action (tried when connected to HF, just enabled BT and disabled BT). Maybe service codes are somehow blocked in this ROM. The only functional i have found is battery status.

what will be the purpose of the toggling app? switch on and off works fine for me, but it just disconnects during using and then reconnect again.
BT is enabled all the time, it is just not able to hold connection. And distance is not the case

[Q] i9000 screen waking itself constantly?!

Recently i put cm11 on my i9000 and now the screen is constantly turning on. As soon as the screen lock is turned on, the phone wakes again.
Sometimes this happens indefinitely and sometimes it only happens once then the screen will sleep after a second press of the lock/power button.
The only consistent thing appears to be that when the lock screen is unlocked the recent apps are always shown.
I've tried formatting/wiping and different night lies and the m4 snapshot but it all happens exactly the same.
Any help would be greatly appreciated.
use this and see if it's the rom or an app that's keeping the phone awake http://forum.xda-developers.com/showthread.php?t=2179651

Thanks, I've installed this earlier today and I don't quote understand it.
According to wake lock detector, under screen wake lock, running and usage, phone - system (radio) is number one.
Does this mean it's the rom keeping the phone awake?
Not sure how wakelock works to be honest but I don't think it's the rom that's the problem, it sounds like its the radio (modem) try flashing a different baseband for your region and see if that fixes the problem? http://forum.xda-developers.com/showthread.php?t=1870460 http://forum.xda-developers.com/showthread.php?t=1158783

Tried several different radios without any success I'm afraid.
Just tried flashing stock JVU rom and then back to CM11 without any success. Exactly the same issue.
Oddly, if you hold the home key whilst pressing the lock key, the screen turns off and stays off for a while, then wakes after a minute or so again.
New Method
Try going into settings>Applications (or Apps)> Running and check which application(s) is taking up the most memory, it may be that a application from an unknown source is waking up the device, like a virus or your phone is consuming too much RAM. If this is the case try and delete it or run a security scan from the play store such as BitDefender.
Another option is to run a more stable version of CyanogenMod instead of a Nightly, I had problems with Nightly builds and changed back to a stable build. Try the new 4.4 snapshot of CyanogenMod, it is more stable. DOWNLOAD from the official cyanogenmod website, don't update using the option in settings as it always sends my phone into a boot loop. Hope it helps
Try another ROM
Let me know if switching to another ROM helps. I'd suggest Paranoid Android or OmniROM.
The thanks button is right there! just saying...

No luck unfortunately, I think I've narrowed it down, and the menu button keeps activating itself.

Have you erased each and everything? /data and stuff? also, just see if Touchwake is enabled by any chance
I don't mean to drag this old thread back up, but I've come to use my i9000 again as a backup device and it still has this same problem.
Is there anyway I can prove that it's a button that's faulty (for instance)?
I thought maybe a logger that would show if it detected/logged the home button being pressed when I notice the screen turning itself on, but I can't find such an app.

[Q]Suddenly shutdowns on MI3 Need help

I'm using mi3 with Euphoria-OS 0509 version. My phone will suddenly shutdown itself even the battery is full.
I tried re-flash this ROM, but no help.
It happens every time when I use the phone in no time. But It won't happen when charging.
Maybe there's a problem on your phone's battery. Try to bring it on a service center.

What do you mean by "suddenly shutdown itself"?
Do you see 1) the closing down routine? Or 2) does the phone simply not respond to pressing the power button?
If it's 2), plenty of ROMs exhibit the "screen OFF death", where the phone is actually still active but you can't get the screen to light up. try flashing another ROM. Paranoid Android is the most stable ROM for me.
If it's 1), still try flashing another ROM, and it it is still closing down, it's a hardware issue (hopefully battery), so service centre time.

In my case, my phone's screen will suddenly frozen while I'm using, and turn off itself. I need to hard reboot the phone. I used flashed this rom few months ago and change to PAC rom, no such problem until I flash this rom again, all roms were clean flash and the battery was calibrated. So I think it might be the hardware problem.

Well, if the phone was OK with a different ROM, that implies your current ROM is the problem - try another one.
I recall having had the same behaviour in the past, when I was trying a lot of ROMs in quick succession - so I don't know which one(s) it was.
All the same, it doesn't sound like hardware/battery. Make a Nandroid backup in recovery, then flash eg PAC ROM or Paranoid Android - wait a day before adding all your apps etc - and see if you get that issue again.

OK, I got some conclusions, and it might be a hardware problem.
First, I replaced the battery with same ROM, it still got SOD.
Then I flash Omni, PAC, Euphoria-OS, all got SOD like before.
So I return to MIUI, no SOD, but I got random reboots and sometimes Wi-Fi will disconnect itself even in its range.
Now I'm using Ivan's AOSP, still got random reboots and Wi-Fi problem.
And now I need this phone to work because I don't have a backup, waiting for new Nexus!!
