Error messages seen in syslog. First two cause no networks to be seen.

SDIO Command failed

Responses to SDIO commands not sent from wifi chip. I believe this happens when the baseband is in reset for a critical part of the wifi initialization. blacksn0w appears to make this problem worse.

Error initiating scan request: 35

This is a generic scan request fail. If wifi still works(like in third party apps) but only scans don't, this is probably the error. No idea what causes this.

Grayed out Wifi
