Help - One computer with extremely slow internet

[archTECTONIC]

Hi All - I just recently upgraded my home network with a new dedicated modem and new wireless router. Every other device is working as expected except for one computer that almost non existent internet speeds (below 1). This happens on both wired and wireless connections, it was working perfectly fine prior to upgrade. 
 

I’ve set the QoS setting to the highest priority and still no change and it’s not blocked in my router or metered.

 

I have no idea what could be causing this. Maybe a BIOS update is needed?

Sounds like a Windows-side or driver-side issue. Try spinning up a Linux USB stick and seeing if that reflects the faster speeds you were expecting from the computer. Considering it's both Wi-Fi and Ethernet with the same problem I think that might be what's going on

@DaJakerBossseems like you've got the right intuition there. fired up an ubuntu drive i had lying around and my speeds are back where they should be. I previously checked the drivers for my pc network hardware and the utility said they were up to date....maybe i need to manually update them?

 

Solution Update: maybe this will help someone out in the future -  after running through system configuration and turning things on and off found out is was a program called cFosSpeed that was the problem...ironically it’s bloatware that’s supposed to make your internet connection better....deleted that with extreme prejudice.
