Having problems with your Dell Latitude C400 Notebook ?

Ethernet port not "active"

\015 My Dell Latitude C400 LAn/Ethernet port doesn't appear to be functioning. There are no link /data lights when an Ethernet cable is plugged in. When cable is unplugged it does show that a network cable is unplugged message. I checked the device manager and it shows that the 3Com 3C920( 3C905C-TX) is working properly. I even installed fresh drivers for the 3Com 3C920( 3C905C-TX) . Still not picking up connection. \015\012Can it be a bad LAN/Ethernet port??\015\012Can I get a cheap mini wireless card to bypass LAN/Ethernet??\015
