We just moved houses, and in an effort to modernise the new house, we've begun to pull CAT7 cables through, from the router to a switch, and then on to perhaps another switch and an access point. I have a 500/500 connection with my ISP (https://www.speedtest.net/result/a/4323520476).
I made a diagram here (not enough rep to post directly):
I have a gigabit access point, and 2 gigabit switches (netgear GS105 & TP-Link TL-SG108). Both switches get a 1000 mbps connection to the router over the first CAT7 cable, but any device I hook up to the switch only gets 100 mbps over CAT7 (the blue line). When I use a cat6 cable from the switch to the AP I get gigabit. The strange thing is, that when I use the 100mbps CAT7 cable to directly connect the AP to the router, I get 1000mbps!
Do both my switches somehow throttle network speeds when using CAT7?
