Hard Wired Network/DHCP Problems

[jackintheboxe]

I am running a wireless network using a linksys B/G router with all the wireless computers on the B band, and then one computer hardwired to the router. Unfortunately, the one ahrd wired computer refuses to be assigned an IP address (and thus cannot join the network/gain internet access) via the router via DHCP though when I run ipconfig, it shows that the hardwired computer's IP is in fact 192.168.1.100 (where the router is 192.168.1.1 and this computer is wireless and 192.168.1.101).
What do I do?

Welcome :)

There is nothing wrong with 192.168.1.100 as an IP address. What is the problem?

The computer with the 192.168.1.100 IP address is the one hardwired computer on my network. I only know it has this IP because I used ipconfig, otherwise (as far as I can tell) windows itself doesn't believe it's been assigned an IP from the DHCP Server (the router) and therefore cannot access the router via IE nor the network nor the internet connection via the router. Not only that, but checking the router using another computer on the same network, in the DHCP Clients table, it lists the hardwired computer by name with the IP address 192.168.1.100. But still, whenever I go to My Network Connections and click "Repair" on said connection, I always get the error that it could not renew the IP address.
Any thoughts?

Goto to the TCP/IP Properties for the connection.

Is it hardcoded or set to Automatic?

Currently, it is set to automatic, but I've also tried manually assigned it an IP address that way as well, using the DNS info from the router itself and forcing the computer to 192.168.1.100.
