NIC misbehaving

[puggit]

My Linksys LNE100TX NIC keeps bouncing up and down like (well... ;))

Any ideas? It's not the cable, and I've reinstalled the drivers :confused:

NIC is connected to a Linksys wireless router - hopefully that is NOT the problem :eek:

Strangely the router failed at the same time... but I reset that and all is well.

Have reseated the NIC and that appears to be working, so I now have a spare £5 NIC from PCWorld
