Do a search and you will see the details. Basically 2.82 introduced a auto reboot feature when changing and OTA channel. Does not effect all users, but it does effect a lot in varying degrees. You can see details and opinions in the 811 forum.
I think I have p282 and I just got my 811 yesterday. I check the sys info and it reads p282land-n. Is this the same p2.82 that everyone else is talking about and if so, why did I get it if p2.82 was cancelled
