I had to replace my old router for my dsl internet. The new router is a D-Link dsl-2750b. I have a Netgear WN2000RPT extender that worked just fine with my old router. The xbox is in my sons room which is close to the extender. We have used an ethernet cable from xbox to extender for a long time and it has always worked. I configured the extender to work with the new router, and for connections like my laptop the extender does its job. This new router has a password, old router didnt.
Now whenever I try to connect to live I get the "cant connect to the internet" error. On xbox live test it fails on the first part, network. I have tried everything, even disabling the routers password but nothing works. Am I missing something? Please help I have been working on this for a week and I am completely lost.
