I do not currently have a long enough cable to accomplish this. For now I’ve instead decided to share my phone’s internet connection with my PC through USB Tethering to see what happens.
Sure enough, my connection is now consistently faster and more stable.
Here is my connection using my pc’s wifi as of now:
and here is my connection over USB Tether (Internet over Mobile Data was disabled for this test, phone displays as Xfinity due to it being a carrier variation provided by them):
Once I’m able to connect my PC to my router via cable (either by securing a long enough cable or by obtaining a shorter one and moving my setup into the same room), I will conduct another test as you’ve requested. While using USB Tethering is a working solution for now I would much prefer not having to do that, so I still hope something can be done regarding my PC’s own WiFi.
If it helps my motherboard is a B650M C V3-Y1 from GIGA-BYTE Technology, which has Wi-Fi 6 802.11ax built in.
