My motherboard has a Killer e2200 Gbit nic. It's been fine but today it's only working at 100mb. I've tried various drivers and cleared my system reg with CC. The garbage bloatware that comes with the driver set says it's @ 1Gbit but it's not. My downloads won't top 98/100 when they're usually up in the 120/125 mark. Opening the nic's properties up and checking the speed and duplex option doesn't allow above 100, there's no option for full GB. Any ideas ?
