Somehow Wi-Fi stopped connecting on my phone. It is not a hardware issue, as it does work when I perform a reset.

What files do I need to delete to get Wi-Fi back working? I don’t want to reset my phone.

If relevant, model is Sony Arc S, using CM9.

It shows „avoided low quality connection” or something like that. –  kinokijuf Aug 31 '12 at 8:05

I removed /data/etc/wifi, /data/misc/dhcp and /data/misc/wifi and it worked.

This is what worked for me:

  1. Turn off wifi (this may not be necessary)
  2. Remove /data/misc/wifi
  3. Reboot

Another possible option: FXR WiFi fix and rescue

Just remove the data/misc/dhcp, that's the 'registration' file which has to be reset.

Your answer has already been answered here android.stackexchange.com/questions/28567/… I see this redundant. –  Firelord 9 hours ago
It's possible this new answer is more correct, because (according to this answer) only the one file needs to be deleted. The other answer includes two other files that must also be deleted, so this answer may be an attempt to be more concise, not redundant. –  Stephen Schrauger 9 hours ago
Of course, the answer as-is may also be incorrect (I didn't test it), so it may be a good or poor answer based on that, but I think it isn't redundant simply by itself. –  Stephen Schrauger 9 hours ago
