Cannot connect UPnP - Archos 605 WiFi Digital Media Player

Since you aren't specific about the model of Belkin router you are using, I can only give you some general advice. This is what is have from MY Belkin router manual. Yours may be different....

Enabling/Disabling UPnP
UPnP (Universal Plug-and-Play) is yet another advanced feature offered by your Belkin Router. It is a technology that offers seamless operation of voice messaging, video messaging, games, and other applications that are UPnP-compliant. Some applications require the Router's firewall to be configured in a specific way to operate properly. This usually requires opening TCP and UDP ports. An application that is UPnP-compliant has the ability to communicate with the Router, basically "telling" the Router which way it needs the firewall configured. The Router ships with the UPnP feature disabled. If you are using any applications that are UPnP-compliant, and wish to take advantage of the UPnP features, you can enable the UPnP feature. Simply select "Enable" in the "UPnP Enabling" section of the "System Settings" page. Click "Apply Changes" to save the change.

Your 2wire 2701HG-B does not have uPnP.

Once you have enabled UPNP on your router and saved the change, restart your router and your PS3, then try. That should get them on the same page and the PS3 to read that UPNP is enabled.

For the UPnP architecture to work in Windows XP, the Internet gateway device must appear in Network Connections. To make sure that the device appears in Network Connections, click Start, click Run, type ncpa.cpl, and then click OK. Look for the Internet Gateway device:
