Ethernet port locked at 10 MBPS Full Duplex after lightning strike

[Gazpacho146]

Hey everyone. Roughly a week ago, my house got struck with lightning, effectively killing my Belkin AC1200DB router. My ISP gave me one of their default routers, I don't really know much about the router they installed, but, it was garbage so I ordered a replacement AC1200DB. Prior to the strike, I received about 20MBPS, give or take a few, on speedtest.net. The ISP replacement only gave me 10, and currently with my new AC1200DB I'm still getting 10. At first, my new one didn't work via Ethernet at all, and I had to go into the settings of my adapter to change the speed/duplex to a 10MBPS Full Duplex, and as a result I'm capped at 10 MBPS. Does anyone know what could possibly be going wrong? When I use Wi-Fi with the new router, I get the 20 MBPS, but the connection isn't as reliable as my wired one. Does anyone have any solutions?

Change the settings to 100MBS Full Duplex or whatever you have as the highest. Leaving it at 10 limits you to 10.

When I do that it says my ethernet cable is unplugged.
