I have 800 fiber internet and, until recently, was getting 800+ Mbs download all all the laptops and two desktops in my house. However, now I cannot seem to get any speed over 200Mbs on my desktop, but all the other computers in the house get 800+ Mbs download when hardwired to the router. I have the latest firmware on the router, and have tried every sort of cable hookup that I can, all using CAT8 cable. I had a 2.5gb port on my computer and was using that, but recently upgraded to a 10Gb LAN PCI card, but the speed has stayed in the 170-180 GB range no matter what I do. Any ideas on how to resolve this?
