router or desktop problem?

I have an internet connection problem, and must tell you that I know very little about this technology. In other words, anyone kind enough to help me out, please keep it simple.

Setup: DSL connection. Router: D-Link DI-713P Desktop and the laptops all run Windows XP. The laptops have DWL-650+ wireless cards. There is no problem with them. The problem is with the desktop Dell Dimension 4700. It is connected directly to the router.

The Windows device manager shows under network adapters: Intel Pro /100 network connection. It tells me that it is working correctly.

This is the problem: Everything worked fine for months. Then, I noticed there was no internet connection after I booted the machine. After a while, there would be an intermittent and very slow connection. Now, there is nothing. When I ping 192.168.0.1 I get the message that the host is unreachable.

When I do an ipconfig /release, there is nothing in the connection-specific DNS field. The IP address and subnet mask are both blank.

When I do ipconfig /renew I get the message that an error occurred while renewing local interface connection: unable to contact your DHCP server.

Ipconfig /all shows: node type: unknown IP routing enabled: no WINS proxy enabled: no Connection-specific DNS suffix: blank Description: Intel Pro /100 VE Network Connection Physical address: 00-11-11-9E-7B-06 Dhcp enabled: yes Autoconfiguration enabled: yes Autoconfiguration IP address: 169.254.70.245 Subnet mask: 255.255.0.0 Default gateway: blank

Questions: Is there a way I can tell if the problem is with the router or the integrated network card? If there is a problem with the router, is there anything I can do short of replacing it? If not, can you recommend a DSL router that is compatible with the DWL-650+ wireless cards?

Let me know if you need any other info. Thank you anyone who can help me with this.
