Firewall on both end (router-ap and laptop) is disabled.
I can't do netcat on the server since it's not a PC box. It's an all in 
one unit (ADSL modem+AP+router). But I did wireshark on the laptop before 
reading your email. And I can see many TCP retransmission while trying to 
browse. If you like I can attach the log and send it to you. 


As comparison, I also do wireshark while using ndiswrapper. I can find TCP 
retransmission while using ndiswrapper, but doesn't really affect browsing 
or large file transfer through SMB.


PS: If you prefer netcat, please tell me, I'll do that and send the log if 
you like.

The AR2425 is able to obtain IP address from the router, 
able to ping with good results, but can't browse at all.
Below are the info on my setup, if you need more info please let me know.

Driver version: compat-wireless-2008-11-24.tar.bz2.
Kernel: 2.6.27.4-2mnbcustom (mandriva), compiled with mandriva provided 
..config but without any WLAN support except WIRELESS_EXT.
Access point/router is configured to use channel 1 (2.412GHz).

dmesg:
