Wifi Error on CM7 build 11/25/11
So I haven't used wifi on my phone in quite some time, but I decided to try it out after I updated to the newest CM7 build. I flashed it over the previous build, wiped the cache, and rebooted. When I booted, I ran the fixdataswitch script just like Jackpot's instructions say, rebooted, and now I'm stuck. When I try to enable wifi, it stays at "Turning On..." for about 20 seconds and then just says "Error". 3g works just fine. I've tried fixing permissions, and wiping my cache and dalvik cache, but still no dice.
Does anyone have any advice about what to do from here? Is there another file I need to wipe? I don't use wifi on a daily basis, or even a monthly basis. The last time I used it regularly, I was on rooted stock, so I have no idea when I could have messed something up.
Anyway, I could use some help here. I need wifi when I travel, and I'm about to hit the road in 2 weeks or so.
