Possibly, but for reference, my Edimax EW-7811Un has been running for 37 hours.
During that time, I have had no deauthentications and only 2 instances of the
"AP lost" reconnections. The latter is what I am currently trying to fix, but at
that error rate, it is difficult. I am running the latest 3.11 kernel from
wireless testing.
The only thing I am doing that is unusual is that I am pinging my router at a 5
second interval using the command
ping -i5 192.168.1.1
It is possible that I am preventing a power save operation, which is making a
difference.
