T-Mobile 5G Home Internet Gateway slow ethernet but fast WiFi

I recently installed the grey 5G Home Internet gateway at home. When I first got it three weeks ago, I was seeing speeds of 150+ down, and 50 up on both WiFi and ethernet.

Now I am seeing roughly the same speeds over WiFi, but ethernet speeds have dropped to 10-15 down, sometimes as low as 5. Upload is around 15-20.

 

Has anyone else had this issue and found a solution? Or is the gateway defective? Both ports appear to have the same issue, and WiFi continues to work fine.

Im having same issue but on wifi and ethernet on pc connection only getting 1.5mbs on cpu wired or using wifi.

25mbs on wifi on all other devices.. checked settings signal all good .. at this point be happy with 15 down on pc
