I first tried an Actiontec cable/dsl router and set up the WAN address, subnet mask, and gateway as provided by TC. But I can't get outside. Obviously I can reach the admin screens on the WAP. I was using this device for years before on a TC cable.
So, now I have purchased a Gigabyte Aircruiser BR02G, and still can't connect

I can't ping TC's dns servers, but on my Telecom adsl connection ( which I plan to disconnect as soon as I get this TC cable working ), things work fine, and I can ping TC at 203.96.152.4
Suggestions?
