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 guess it said avoided poor Internet connection, right? –  Izzy Apr 27 at 11:15
@Izzy translation differences. –  kinokijuf Apr 27 at 12:48
Especially if your system language isn't set to English, yes :) But my link still points to the same issue you're having I think? –  Izzy Apr 27 at 12:56

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

For readers: I rejected an edit suggested by a new user for this post who had this to say: "Don't do this. You will simply lose the wi-fi connection function altogether after reboot. This procedure will ruin your wi-fi connection for good and force you to hard reset your phone. Pure sabotage.". // I found it worthy to be mentioned so I posted a comment on the user's behalf. –  Firelord Jul 18 at 14:27

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
