So the AP is disconnecting the device a couple seconds with reason 4,

points to a driver bug (Larry?).
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.
Hi Larry,
For comparison, what does your device report when plugged in? My device
reports this:

Also what type of USB port are you using? I'm plugged direct (no hub)
into a ehci-pci port on a laptop if that makes a difference to power?
ATB,
Mark.
