I use a tp link that has worked before with my xbox at 1 gigabit it is a hub one I have a b450 tomahawk max and I don't know about the ethernet drivers I have not installed them but the ethernet port works at 100mbps but it's supposed to be 1gbps
For testing remove the Powerline adapters from the equation (assuming that's what you're referring to as 'tp link').
Are you doing anything that needs a connection faster than 100Mbps?
That motherboard appears to have a Realtek 8111H Ethernet controller. Google '8111H 100mbps', or similar, and see if other people have had the same issue and found a solution.
You really need to try without the Powerline adapters. It's a basic fault finding step. If you don't, and they are the problem, you'll never find a solution. Them working previously, with different equipment, proves nothing.
If you haven't got a cable long enough move the PC or router so they are close enough. The router doesn't need to be connected to the phone line to check whether it connects at Gigabits speeds on its LAN ports.
