NAT type always on unavailable

NAT type always on unavailable
Ever since I put a second wifi extender in my room so my smart tv can have a wired connection too, it must have tripped the connection for my wired xbox as now its stuck on NAT Type unavailable since then, i tried swapping the plugs, cables, port, force
reset router and xbox, re searching for the plug again etc. And nothing works, it could be a physical problem, but my tv works fine with both cables, so it must be something to do with the NAT on the xbox, it used to be Open, and it still is on Open on wireless,
but my wireless internet isnt very good.
