Experiencing very slow browsing at times (atheros wireless)

I recently purchased a new atheros based WIFI card.

I am using no encryption at the moment. I can ping all websites and the ping times are fine.

They are my normal ping.

However, browsing web pages often slows down to 0kb/s (i can still ping though).

Speed is almost always 54 or 48Mbps.

Any ideas what might be happening? Before someone says DNS, no its not DNS, my DNS and host configuration has been working for 2 years now on DragonFly (only recentely i moved to wireless). It's not upstream connectivity either because all other non dragonfly boxes work even when this box is experiencing the slowness.

Thanks,
petr
