I didn't read some of your other posts. But, if you are able to post when directly connected to the modem, you need to register the router's MAC address with your ISP somehow, to get online. You can try releasing the MAC address and/or IP associated, and then power cycle, but ONLY have the router hooked up. This normally works. And this is under the assumption you have cable.
What ISP do you have?
As far as the drivers go, you probably would have been better off, NOT installing the drivers off of the CD. There are updated ones on Intel's site. Even LAN drivers there too probably. But, most importantly, Vista has a lot of drivers in the installation, that it should have worked just fine right out of the box, and upon installing the OS.
