I have noticed issue like this while using ppp connection. I am using wlan0 that is connected to a WPA connection.

uname -a
Linux goldgriff 2.6.34-gentoo-r1 #5 SMP Sun Aug 15 12:58:25 MDT 2010 x86_64 Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz GenuineIntel GNU/Linux

Any ideas on where I should start? Am I missing something in my kernel config?

Thanks

Chris
