So I left for vacation, came back, powered on the server and it just negotiated 1Gbps like it's nothing... I've spent 3 days on trying cables, switches, upgrading firmware, BIOS and anything else I can think of or find on the internet and nothing helped, and now after like 5 days sitting powered off it just magically starts working I feel like it's been making fun of me now
I have exactly the same issue with this exact motherboard - trying to plug in to my temporary 1Gbps switch (while waiting for a 10Gbps one) it only negotiates at 100Mbps no matter what I do...
Has anyone managed to solve this somehow?
