No wifi bug here at all, just one issue that I cannot seem to figure out why it is not doing anything, sitting @ 3% restoring missing apps with Titanium Backup Pro.. Weird and I even did a Reflash with this as well...Wifi bug is due to the firmware. Firmware is not an app, it's the programming that makes your hardware function. Each "base" uses different firmware. This is a pre-release, so it's normal to see these kinds of bugs.
Cheers,
