Okay, been running the CM7 rc4 on my droid for awhile now, and the previous versions of CM7 before that. No issues to report. Occasional hiccup, but nothing major. All systems have functioned great. Yesterday, I returned to my desk after being gone for about an hour for a meeting. Found that several applications had self-updated while I was gone. After a bit, I realized that my wifi wasn't connected. I checked, and wifi on the phone was turned on, so I thought maybe the wifi at the office wasn't work, but found out it was working fine. Turned on wifi analyzer and it didn't show any signals anywhere in the area even though I know there are at least 4 different networks. Did a reboot on my phone, still nothing. Go into settings, went to airplane mode, then back to regular. Wifi still does nothing. Went back to my restore point which was over a month ago when I updated to rc4, after reboot, my wifi came right up and was working fine, but when I returned to the backup I made yesterday, I again lose wifi. So I know it has to be something in one of the updates from yesterday, I just don't know what it is. I really don't want to go back a month and have to redo a bunch of stuff I have done to my phone since then. Has anyone heard anything about this before and do you have any suggestions that could fix the wifi problem, other than the obvious of restroing the month old backup and reinstalling a bunch of stuff?
