PC IP : 192.168.11.5
O/S : Windows XP SP3
Firewall : none, and I turn off my PC's firewall already.
N900 IP : 192.168.11.6
Router : Buffalo WZR2-G300N, and I didn't see firewall or restrictions settings, gust mode?? what's that?? , my router security use WPA-PSK(TKIP).
All that sounds OK, so I would double and triple check all the settings etc. In your original post your screenshot shows a different IP...
Oh and it was a typo - I meant guest mode. I've seen some routers which can do this, but heavily restrict the guests to port 80/443.

May the source be with you.
