[ath9k-devel] Poor performance on AR5418

[Amit Sood <as22_2000@yahoo.com>]

Hi Luis,

I'm using static IP address on wifi interface. Its almost immediate once interface comes up, if I try to ping to gateway or any other system in same subnet the there is packet loss. If I try ssh or any other service on that interface the session becomes slow like for a while stop responsing (like used to be using dial-up service to a remote machine).

Let me know if you need any specific logs etc. I'll be more then happy to provide that.

cheers,

-amit-

Directly. I didn't at any point get a good link.
