My e2200 nic is recieving only 100mbps instead of 1000. when i plug the brand new cat6 cable into another machine with stock intel nic it gets full 1000. i have tried the latest driver for the e2200 and set the speed and duplex to auto negotiate, which is what every other forum recommends. there is no option to manually set it to 1000 in my driver settings. i tried to manually set it on my router (asus rt-n56u) but it bricked the connection. worked fine on the other machine so i have ruled out the possibility of it being the router or the cable.? The killer app has options for up/down speed but they do nothing. There are no other options. What other steps can i take? is there a bios setting, some kind of registry hack I can do?

Router - ASUS RT-N56U (with three other machines receiving 1000/500)
Cable - Brand new CAT6 that works perfectly on the other machines
Bad NIC - Killer e2200
Bad machine - MSI GE70

Uninstall the NIC and REMOVE all the driver and bloatware package that comes with it. Download JUST THE DRIVER PACKAGE not the application that can be bundled with it. Install and you should be good. The killer NIC application is buggy as hell and is completely pointless.

Thanks for your reply. I tried that multiple times also. Same results - only 100mbps down with both current and legacy drivers, with and without the killer app. Are there any other often overlooked settings / crazy things that could possibly stop auto negotiation from achieving 1000mbps? Getting quite desperate here as I've tried all the obvious stuff. Auto negotiate seemed to fix it for everyone else
