Cannot get gigabit performance out of Nics in Win 7.. Locked 100 mbps. My motherboard is an Evga 590 Sli Am2 motherboard, with dual gigabit nics. Having established that there is really no benefit to using both nics at the same time in another post, I am now posting because it seems I am only getting 100mbps out of my nics, even though all the cables in the network are cat 5e, and both the router, and switch in the network are gigabit capable.
I started researching this problem some time back on the net, and came across threads where other folks were able to resolve, by installing their specific network driver
from mobo maker, as opposed to the network driver bundled with chipset from nvidia. I did some footwork then with drivers
, and was able to get my machine running at full gigabit speeds. It ran this way for the past few weeks, then when transfering a 1gb file from one machine on the network to another the other day, noticed that the speed was locked at 100mbps. I went under task manager, network, and noticed that the speed was back to 100mbps.
I am posting here to see if anyone has any advice. The only option on my nic controller config and the one I used to get it working before, is auto negotiate. Gigabit is not listed.
Any help greatly appreciated..
