Why is my windows 10 machine’s internet getting 30mb via wifi on a 650 mb connection?

I have a 650mb/s connection from virgin media, which is mostly working fine, I get anywhere up to 600-650mb/s on every device I I own (samsing s20, iphone 11, 2 macbook pros) except for my Windows 10 PC.

Now I will say, I only have a 300mb/s capable card, so i know i won’t get the full speed, but i’m consistently getting 30-50 mb/s down on this device.

Here’s what I’ve tried so far:

  1. Switching to Ethernet (this works, speed jumps to 600-650mbs, but is not a viable long term solution given the path from router to PC)
  2. moving the PC closer to the router (moved it to within 5 feet, unobstructed, no change in speed)
  3. I set the autotuning level to normal via cmd
  4. I tried flushing the DNS via cmd, this threw no errors, but changed nothing speed wise
  5. Checked my programs list for any bloatware of application that would possibly limit my speed, anything I was unsure of, I removed, including the nvidea suite that did nothing to help the speed and was a pain to reinstall
  6. Spoke to Virgin Media who told me the problem was definitely on my end and there was nothing they could do

I’m at my wits end. If I don’t find a solution to this, I’m going to have my house totally wired with cat6 so wifi is no longer an issue for any reason.

Any help would be appreciated.

I have attached a screengrab from SamKnows to show the inconsistency between connection to router and connection to machine.

Thanks!
