Are you running default settings or have you done any configurations or just default settings? I presume that the reboot is the entire unit and not just wired or wireless? This is beta 08 and I did notice alot of random wireless disconnect on my A1 hw. Wired was good and stable. Since ur on Beta 08, I would suggest going to Beta 03 1.21NA, 2009/09/18 and try it and see if it does the same thing. I'm also on Beta 03 since I was getting tired of the wireless disconnects. Beta 03 is working well here. Let us know.
