Thanks, I have already reset to factory default so now know it is not using a static ip address.
My wireless network is working fine, all my wireless devices (PC and laptop) connect okay.
The M1001 confirms that it is connected to my WLAN.
My WLAN connection uses USB Wireless 802.11 b/g Adaptor.
UPnP is enabled.
I have tried with no security, WEP and WPA.
I went through the static ip address set up (http://soundbridge.roku.com/support/static_ip.php) and followed it exactly but cannot telnet to the roku once I have changed my computer connection's TCP/IPv4 settings. Is this the correct internet protocol I should be updating as I have the option of v4 or v6?
