Unable To Turn on Wi-Fi

mbrentrowe · Apr 23, 2012

I'm having an issue with wi-fi. I'm running Andromadus Audacity 2. Yesterday I ran into an issue where my phone was randomly rebooting. I decided to reflash the rom and when I did so I could no longer connect to Wi-Fi. I can turn Wi-Fi on but it will immediately turn back off. In settings it will only say turning wi-fi on and hang up there.

I don't think that the issue is the router since my wife's G2 and other devices we have in the house still work fine on wi-fi.

Also it's not the rom because I have superwiped and reinstalled, then tried installing cm7, and ilwt. The issue persists on each rom. I have superwiped each time before installing.

I am really at a loss for what to do, I didn't change any settings on the phone and regardless, I don't know what I could have changed that would have carried over through flashing a new rom. I would appreciate any ideas on what to do.

ETA - I have changed the radio and the kernel and still no luck.

Sorry accidental send, check the /etc/wifi/wpa*.conf permissions and ownership. This happened to me when that file was off.

When you say off do you mean it was absent?

When I got to /etc/wifi/ there is a file named wpa_supplicant.conf, it is the only file in the folder

the text file says:

update_config=1
ctrl_interface=wlan0
eapol_version=1
ap_scan=1
fast_reauth=1

Sorry my English is not as great as I wished it would be, this is what happens when I try to use "slang". When I say off I mean not correct. That is the correct file "wpa_supplicant.conf"

/etc/wifi/wpa_supplicant.conf --> needs rw-r--r--
/system/bin/wpa_supplicant --> needs rwxr-xr-x

I just checked my files and they are both owned by root and all works well so I guess its not an issue that wifi does not own them.

Sorry I just misunderstood.

I checked both files and they had the same permissions that you wrote out.

Not sure if this helps but this is what's under my /etc/wifi/wpa_supplicant.conf file
update_config=1
ctrl_interface=eth0
eapol_version=1
ap_scan=1
fast_reauth=1

Notice my ctrl_interface=eth0 (thats a zero) I'd test that out see if it fixes it, if not then I'd download another rom and extract both /etc/wifi/wpa_supplicant.conf and /system/bin/wpa_supplicant files from it and replace yours. Again verify permissions are correct.

Hey I'm on lunch now, in that file it says for ctrl_interface=wlan0. I am using es file explorer, it won't let me change it there but I think I read somewhere I can create a text file saying what I want it to and place it in the folder. Not sure if that will work.

As for the other roms, wifi doesn't work on any rom that I use.

You can replace the file using a terminal emulator here are the steps

Open terminal emulator and log in as super user by typing the following
su
Make the System Partition have read/write access by typing the following
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
Now you can modify the file using es file explorer
When complete make the system partition read only by doing the following
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system

You can also copy and replace the file using adb, not sure how familiar you are with that but the above should work.

Hmmm, I went into terminal emulator and did just as you said. This is what it says after I pasted in what you wrote to give me read/write access:

Usage: mount [-r] [-w] [-o options] [-t type] device directory

After I did that it still won't let me change that file.

Sorry you are correct that command only works in adb do this instead of the above command

mount -o remount,rw /system

then when you are done do this instead of the other read only command

mount -o remount,r /system

Thanks I will try it, but I'm becoming more convinced this is a hardware issue.

I was on the phone today and the phone froze and I had to pull the battery. When I restarted the phone Wi-Fi was working for the first time in a week. While it was working I checked that file and it said the same exact thing. The phone then froze again (I think it was my fault because in the excitement of having Wi-Fi again I tried to update all of my apps and other things I can't do on the crappy 2g data I have at home) when I turned it back on Wi-Fi was no longer working.

So now I'm thinking that this has to be hardware. I will give your method a try.

A_Elizondo · Apr 29, 2012

Yea I think you are correct especially since you tried different roms. If you have warranty just unroot it and return it else keep posting here about the status and a will find a work around eventually

Well I finally switched back to ilwt and my wifi isn't working all of the time but it has worked for a few hours each day since I flashed it. Whereas on andromadus it didn't work at all for two months. Still haven't figured out what happened but at least I get to keep my G2. Although I'll probably move on the first time they put the note on sale later this year. Thanks aeliizondo for trying to help me!
