We just got our new Telecom Wireless Router, a Technicolor gateway. With our old TP-Link Wireless, I could use WDS to link it to my old one, as i hate using a USB wireless dongle. NO i am not buying anything else.
With the new one, this comes up in the settings.TP-Link Settings

And Windows XP can't find a local ip to use.

PS: I'm using my Android Smartphone (Telecom T903) connected to my wifi in airplane mode to post this.
