I have 2 PC's and 2 laptops on my home LAN. Both PC's use cat5's and the laptops are wireless. The problem is, my PC gets slower speeds than the rest.
I'm running Windows 7 64bit. My motherboard is an Asus Maximus VI Hero and I'm using the on-board Intel I217V port. I also have the latest drivers for it.
Currently, speed tests on everything else shows 60Mbps, yet my PC is showing 30Mbps. It's not the cable, as if I plug that into my laptop, it will show the full speed. I keep my PC in good working order, so it has an up-to-date antivirus, firewall etc and I do regular scans. I've also tried disabling BitDefender to see if that was the cause and that didn't help.
