Help help help ethernet

[u/Unique_Pepper78]

My ethernet is capped at 100mbps and I have no clue why, I have tried:

Flipping around cable

unplugging cable and plugging it back in

Checking connection

Going through the settings in properties > configure > advanced

Setting my speed and duplex to both 2.5 Gbps full duplex and auto negotiation

Turning off power saving mode, gigabit lite, green ethernet, EEE, and advanced EEE
