[ath9k-devel] ath9k not connecting to one particular network..

[Outback Dingo <outbackdingo@gmail.com>]

bad firmware load on a crappy wireless AP probably, I just flashed the
latest firmware on a new Netgear, and had exactly the same issue
flashed back to the original firmware and the issue goes away, question is
whats the router and version? Ive seen it before also occasionally
using OpenWRT on some of my home units where a client would simply refuse
to connect, you could also ask the location your staying to reboot
the wireless AP, it might clear the error.
