The PC is running the same WLAN/Wi-Fi connection as the N900. And I have never had any problems with anything on this connection before. My N800, N810, all my Symbian S60 devices, Nintendo Wii, Windows, Linpus, Xandros, Ubuntu PCs all work absolutely fine on this connection with this router. And like I said, everything else works, including Maemo Extras through wi-fi and cellular.
