Open pvianag opened 12 years ago

WIFI status keep "Stablishing connection..." until you delete /data/misc/wifi/wpa_supplicant.conf Obviusly when you delete this file networks you saved are deleted.

This happens with all this versions (maybe more):

This is file needs to be removed each time the WiFi driver is changing/updated, the last change happened in the BOOTWIFI3 nightly.

pvianag commented 12 years ago

It happened without any change of ROM. Now I have the RC. I deleted 2 times this file since I installed it.

pvianag commented 12 years ago

The same with cm7-110926-0834-NIGHTLY-Jordan.zip With this ROM (and also happen with older) more than 2 times I should delete the wpa supplicant config file to restore wifi functionality (always without updating of the ROM)

I had the same Issue, after running the Motorola Defy with the "stable" 7.1.0-jordan for a while, wifi just stopped working. It seems only removing the line: ap_scan=2 from wpa_supplicant.conf already helps (but upon trying multiple things, so I couldnt really isolate it to this one line so far..)

This option seems to be not well documented in wpa_supplicant, but somehow sets the scanning mode of it. Just by guessing: Maybe the Defy Hardware is not compatible with all scanning modes(?). But why this is set(is it?) only after Cyanogenmod ran for a while is dubious. I will investigate further when&if the issue arises again. In the meantime I will sometimes take a look in my wpa_supplicant.conf if this ap_scan setting is added again.

Strange, already today it happened again .. but the wpa_supplicant.conf contents didn't change at all (according to "diff"). Still, removing it and having it re-created by the phone helped somehow.... Anyone else did some real debugging on this?
