Compaq Presario 2175us; WinXpProSp1; NS7.2; Dlink DI524 wireless router.
My internet connectivity is fine, but I keep losing domain name lookup. If I type a url, I get the "name cannot be found" message. (I forget the exact wording.) But if I type an IP address into my web browser, I can get to a web page.
The DNS server is assigned automatically by the router, and is, as expected, 192.168.0.1.
Sometimes, rebooting will fix the problem. Sometimes not. Tonight, for the first time, it mysteriously healed itself. The problem is occurring two or three times a day. There are two other laptops on the LAN, and neither are having any problems.
Any ideas would be appreciated.
