I saw someone on WIFI getting 450+ before?
I have set it up today w/ line of sight, few ft away and direct lan connection to ATT Gigapower (1Gbps).. I am reaching about 215Mbps up and down. Is there some settings to tweak in google wifi?
215mbps is the speed between your phone and the San Diego server you're testing with. Change servers to something in Eastern Europe and watch it drop tremendously. (Speed isn't an absolute measurement, it's "speed between point A and point B" - and if someone's ISP is running an Ookla server, they can be getting close to gigabit speeds - there's one Ethernet node from them to the server.
The Ookla speed test is for negative troubleshooting - if you get 50kbps, you have a problem. If you get 10mbps or more (and you should be getting at least a quarter of your router's speed), there's no problem.
802.11n, with 4 spatial streams, theoretically tops out at 600 Mbps, but that's you to the router, not you to some Commodore 64 connected through bare copper in water in a jungle. Your speed, even to a topologically close testing server, could legitimately be 450mbps or even 212mbps. (I just topped at 39.41mbps, but the nearest Ookla server isn't that close [and I'm capped at 30mbps on this connection]).
