 I have a supplied cable modem slash router on a 300 megabits per second plan. I get about 330 megabits per second. I'm in the office where the router is located. I get the full speed over the 5 gigahertz Wi-Fi. The 2.4 gigahertz is slower, but doesn't everyone have a router with 5 gigahertz these days? Even down the hall, I still get about 250.
