100meg on Gigabit setup...
A strange one, but maybe someone has an idea as to what's going on here...
So; Gigabit network setup; Modem, router, switch, cabling of Cat6 standard.
Just recently my main PC has been getting auto-negotiated at 100 full duplex. It's always been gigabit previously (and annoyingly you can never force gig duplex on a NIC card).
Reinstalled/uninstalled drivers and swapped ethernet leads - But to no avail. Seems bizarre that the NIC card would suddenly only work in a lower speed. I've tested the switch port with other gig devices and it's fine. I even ran a straight run of ethernet from PC to main router, bypassing switches.
Anyone seen this occur before, any ideas for a fix? I almost suspect Windows 10, as it's been updating recently!
Killer E2200 NIC/AC87u/GS116E If it matters.
