A:Answer Bear with me. I measured internet speed and WiFi network speed, but had a couple of challenges.
We have Gigabit internet, but it's currently having some issues. The problem lies with the ISP and the physical wiring, not the modem or router.
If I run Speedtest on the router, I see download speeds of ~93Mbps and upload of 42Mbps. Running the same test from a device connected to the WiFi network, I see 94Mbps down and 42Mbps up. i.e. no loss of speed.
Obviously, at higher speeds I would expect to see a greater disparity between the raw internet access speed at the router versus speed across the network. In the past, I believe I've seen router-side results of 800+Mbps and client-side results of 600+.
If I test *just* WiFi speed, not internet speed, I consistently see 499-535Mbps. That is with 30+ devices connected in a relatively noisy environment (I overlap with multiple neighbors' networks).
I'll update this answer with more numbers if I get Gigabit connectivity back.
However, I will say this has been by far the fastest home WiFi setup I've ever had.
