Was hoping someone could help me sort this out. I just installed a cat 6 network to my office/family room which was on the other side of the house from my modem. I have a wire running from my modem to a switch that is on one side of my office and then a wire from the switch to my computer. In the modem, as well has the switch I have a google wifi point plugged in each as well. My ISP is xfinity and I should have 800mbps. When I run the speed test on the google home app I get ~800 (last run 846 mbps), but when I run multiple different speed tests on my computer I sit in the 60-80 mbps range. Any idea where the issue may be? Thanks in advance.
