I did a search on my phone for *.log after I couldn't find that path you suggested, and all i have is sdcard/fix_permissions.log
Well I was able to flash CM10 back, so I tried your ROM again and it installed without error, but WiFi is still not working. So I go back to CM10, and guess what? My WiFi is acting the same way as it did on your ROM.

The recovery.log will be in /tmp while you are in recovery. When you reboot, the recovery copies that file over to somewhere in /cache. Maybe /cache/recovery_log or something. Search and you'll find it.
Get a logcat of the failed wifi connection and post it on pastebin, I'll take a look to see if anything stands out.
