Depend on the hub/switch speed, the cable may not work with
auto-detect. The cable may be working correctly of the PC so check to
make sure the laptop's ethernet port is running at the same Ethernet
speed (10 or 100) and not auto-detect.
The 'Local Area Connection Status' dialog box lists the connection speed as
100.0 Mbps for both the desktop and the laptop. I don't know how to
control this setting manually, but since the laptop works at 100 Mbps and
the desktop doesn't, I'd guess that this isn't the problem. If I'm
overlooking something, though, please tell me that I'm wrong! Thanks.
