I would think that it may be that you have WiFi interference. Maybe too much on one channel. Try setting the WiFi to different channels that are not next to each other.

  @ArcherC8 tried and no luck. I have locked on every channel one at a time. Weirdly, it doesn't always start off fast, but when it does after a while it drops right back down. 

It certainly appears that I am connected via WIFI faster than the router is feeding me.

If the incomming speed is that low them I would be reviewing the incomming signal such as the cables. You may have a bad cable or bad connection. While doing speed tests, move the cables to see if anything happens. 

  @ArcherC8 well, I think you got me! I looked at my Archer AXE75 and found this. When I first looked, port three was dead and port four was connected at 100 Mbps. I switched the two and now it is working as expected so far.
