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.
