@cmb:
Still haven't had any issues with mine, not sure what to tell you. The 1.2.1 release will be based on FreeBSD 6.3 which has an improved Atheros HAL, you might have better luck at that point. Others who have tried it have noticed a number of problems are no longer issues. There isn't an embedded image available or I'd give you a link. If you want an iso for a full install let me know, there is one of those available.
I reloaded the firmware on the touch a few times and it somehow magically fixed things. At this point I think its an Apple issue that may have been resolved in the 1.1.4 update.
Greetings from the middle of everything in KY, Louisville. ;D I see you have a Logan Telephone email address, one company I work for has a location serviced by Logan Telephone in Radcliff, guess you aren't too far away. Though the project and its contributors span the globe, Louisville is the world headquarters of pfSense. Scott and I, the founders, are both here.
Radcliff is about two hours away. I'm about 30 miles to the west of Bowling Green over near Morgantown.
