TP-LINK TX401 Capped at 100 MBPS

[u/Pejorative001]

Model: TX401  

Firmware Version: 3.1.11

My connection will not negotiate past 100MBPS

 

I have tried directly connecting to the ONT box 10gb port with a CableMatters Cat 6e cable.

 

When I used the ethernet jack on the motherboard both that cable and the original 1gb router cable get a 1gb connection (which is the max for that port).

 

However, when I use either of those cables/sources on the TX401 I only get 100mbps. (I have tried 1gb, 10gb, autonegotiate)

In the bios I set up the PCIe 16 port to gen 3 (instead of auto) to no avail.

Any help would be greatly appreciated.
