Re: [ath9k-devel] ath9k: good, but can I get to the next level?

The other problem I'm seeing is that when I have a lot of clients connected - say, 20 or so - performance degrades pretty steeply and I start seeing high packet loss.  I know that sounds like a pure load issue, but I'd like to make sure it's only that and not some efficiency setting I can
