Sorry for the late reply, being busy with other stuffs.
Anyway, disabling hardware cyrpto didn't make any changes.

Flood ping the router doesn't have any lost packets (although only for a 
minute or so). And my router's log shows that the laptop didn't 
re-authenticate very often.

I've also compiled vanilla 2.6.26 and 2.6.27 with ath5k (compat-wireless). 

- 2.6.26.8 + ath5k (compat-wireless-old-2008-11-29, files last editted on
2008-09-16):
-> ping shows some packets loss.
-> can browse any websites.

- 2.6.27.7 + ath5k (compat-wireless-2008-11-26):
-> ping doesn't have any packet loss.
-> can't browse, browser always waiting for the response from the server.
Monitoring the traffics shows that there are tx packets, but there's no rx 
packets.

Anything else I can try?
