Unable to make internet connection

[piattj]

A friend's asked me to take a look at her laptop ... when I wire it into a router, there's no internet connection.
Tried different ethernet cable, different router port. Still same.
Fails when I ping the router (192.168.x.x), but can ping local loop (127.0.0.1)
Windows shows the ethernet card as working.
Disabled / re-enabled interface. No joy.
No obvious mis-configuration in internet options.
Wireless is OK.
Scanned for viruses (ESET). All clean
Standard Windows Firewall in place.
ipconfig /all shows no IP address allocated, no DNS server, no default gateway etc...
Any thoughts? Thanks...

If you can post a screen shot of the ipconfig/all I might be able to help fix this problem.
