Try this.

Check TCP/IP Properties. Start, Connect To, Connection, Properties, Scroll Down TCP/IP and highlight, click Properties and check that Obtain DNS and IP address automatically are enabled.

Also go into router's setup screens (see documentation that came with router or download manual). In the router's LAN settings check that a setting like "Use Router as DHCP Server" is enabled.
