As a long-time freelancer and work-from-homer, I’ve owned a lot of routers in my quest for the speediest and most pervasive possible Wi-Fi. I had the original Apple Airport, followed by the AirPort Extreme, the Linksys WRT3200ACM, and most recently, the Netgear Orbi RBK50.
Each time I replaced my router, the speeds and coverage boost was measurable but relatively muted. The jump from 801.11n (Wi-Fi 4) to 802.11ac (Wi-Fi 5) was noticeable, but not monumental. And upgrading to a mesh router was easy, but it didn’t deliver a huge leap in coverage over the bridged Airport routers I was using previously (I had configured one Airport as a router, and a second as a range extender). When I wanted a speed boost, I paid for a higher-speed tier from my ISP.
