Internet connection doesn’t change much with an ethernet

I've been stuck on wifi for a few months since moving into my new place and I just got set up woth an ethernet cable finally. But I plugged it in and I got better connection for a few minutes before it just went back to the same speeds. And now it seems that with each test I do it can't stay consistent. I went through and changed to 5ghz and manual DNS, but nothing is working. 2nd photo is on wifi and the other 2 are ethernet. The download improves but upload is still crap and I'm getting terrible latency in games.
