Linksys WAG54G Loses Ethernet Connections

My daughter's Linksys WAG54G appears to have lost its ethernet connections.

I needed to adjust some settings for her and connected my ethernet cable
to it, it showed nothing. This cable connects to my own device fine.

Naturally I tried all 4 ports, all to no avail, tried a different
ethernet cable and this too didn't work.

Strange thing is the wifi part of the Linksys is working fine.

Has anyone else heard of anything similar.
