I've got an HP DV6810us laptop that I just installed Vista on that won't connect to the internet. It can connect to the WiFi just fine, but can't get past that. I've tried unplugging the modem and router, running network diagnostics, etc. Other devices connect fine. Ipconfig /renew says "Unable to contact your DHCP server. Request has timed out." The network adapter is an "Atheros AR5007"

In the laptops, the wireless adapters die often. Has happened to me too. Suggest you get a USB dongle - best would be the Linksys brand to be compatible with your router. They have these cute little mini dongles now. Those do not stick out on the side.
Here is a Netgear example that I just bought: http://www.bestbuy.com/site/NE.....1&lp=8
