XFi wired connection slower than wifi
I currently have an internet plan for speeds up to 600mbps. I understand it is unlikely I will get that speed. However, my iPad on WiFi gets around 500 while my desktop can only manage about 240, half as much, on a WIRED connection. The NIC is 1Gbps capable. On Windows 10, network status is showing 1000/1000 Mbps link speed. I bought a brand new Cat-6 cable and it makes no difference. From reading other posts, my CPU is NOT overheating or anything. I have reset the XFi cable modem, restarted the PC, made sure the driver for the NIC is up to date and still no luck.
I have also switched ethernet ports on the XFi cable modem. How can I get speeds on my desktop to be similar to those on my iPad?
