So, I'm using a 12 foot CAT6 ethernet cable to connect to my windows PC to my gigabit router.


Using a Cat6 cable to connect another Windows 10 PC to the gigabit router gives a speedtest result around 950mbps+.


Using a Cat6 cable on the problem computer has a maximum speed around 350mbps. (this is using the built-in ethernet adapter on the motherboard, and using a pci-e ethernet adapter I recently bought. Both advertise gigabit capability.)


The motherboard I'm using is an Asus Z97-E with 16gigs of RAM and an intel i7-4970 processor. GTX 1060 Rog Strix 6gb GPU, running windows off of a 1TB SSD.


Both computers have the same processor.


I also get around 400+mbps over wifi (5ghz) to my surface pro 4.


Any ideas why the problem PC is capping LAN/ethernet speeds to around 350mbps?


I've tried (none changed anything):

  • Resetting network devices/services
  • A couple command-line "fixes"
  • installing/re-installing network adapter drivers
  • two different 1gbps network ethernet adapters
  • Trying different ports on the router
  • Changing a few different settings in the ethernet adapter settings (can't remember off the top of my head but I went through several)
