I recently configured my home network (Motorola Surfboard SB5100, Linksys WRT54G router) with a sub-50m CAT5e cable to a newly-introduced machine using an nForce4 motherboard. I have typically had issues getting this unit to cooperate with networks. I recall a period in which I had to bypass the onboard NIC by using USB, and that was the only way online. Regardless, I downloaded the latest nForce4 drivers from nVidia's website and installed them, and restarted I terminated the CAT5e cable myself using T568B patterns (as is the custom in the rest of the network). Still, however, the machine in question refuses to recognize incoming packets. There was a time, just after I installed the cable, in which the network connections monitor said that I was connected to a 1.0Gbps network, and then I restarted and it returned to saying "A network cable is unplugged." Any suggestions?
