Hello, Wireless.
I have true 802.11n client in my home now -- Blackberry PlayBook, and
my software AP shows many "ath0:" device timeout" when I use it.
With 802.11g client only it works perfectly (if this word is
applicable to my very noisy environment), without any errors.
But as long as PlayBook associated with AP, driver starts to show
"device timeout" every 3rd minute. PlayBook drop connection on each
AP's device timeout :(
My AP hardware is:
