I had the Dec. 31st nightly of CM11 running and decided to update it to the Jan. 11th nightly. I cleared the cache, dalvik, and format/system in CWM and flashed the new rom. When I rebooted, everything seemed to work ok, but there were no wifi networks detected. I tried downgrading back to the Dec. 31st nightly but still encountered the same problem. I tried the same thing again but using the wipe data/factory reset option in CWM before flashing, also to no avail. Any and all help with my issue will be very appreciated. Thanks!
