Hi,

My main PC's upload speed has been cut to 5% of what is possible and I'm trying to find the reason why this is happening.

The speed is normal on other PCs, both over cable and wifi.
  • I've tried with cables that work on other PCs.
  • I've updated the NIC drivers.
  • I've tried installing an external network adapter and installed the latest drivers on it.
  • I've tried restarting the router and switching ports.
  • I've tried closing the Peer to Peer Update Process in Win 10
  • I've tried adjusting Internet Bandwidth in gpedit.msc
  • I've tried disabling window auto-tuning
Any ideas?
