Every person needs good WiFi in their homes, but a lot of domestic WiFi setups suck for countless reasons. Maybe the hardware your ISP gave you isn’t great, or your walls aren’t friendly to wireless signals. Or perhaps the signals from your all-in-one wireless modem and router just can’t reach everywhere from its spot in a far corner of your house. It’s these maladies that mesh systems deal with, a distributed set of smaller WiFi nodes that are spread around your home, pushing internet into every corner. Mesh routers aren’t new, and we’ve reviewed plenty, but now we’re building a one-stop shop for everything you need to know. That’s because WiFi 6E is mature and affordable enough to offer transformative wireless performance for everyone.

WiFi
WiFi is governed by the International Standard IEEE 802.11, and every few years the standards evolve. Until 2018, routers were sold under their IEEE designation, leaving consumers to deal with the word soup of products labeled 802.11 b/a/g/n/ac et cetera. Mercifully, wiser heads opted to rebrand the standards with numbers: WiFi 4, WiFi 5 and WiFi 6. We’re presently between two WiFi generations, WiFi 6 and 6E, which relates to the frequencies the standard uses. WiFi 6 covers routers which operate on the 2.4GHz and 5GHz bands, while the latter means it can also use the 6GHz band.
Each WiFi band has tradeoffs, because the slower radio frequencies have greater range but less speed. 2.4GHz signals will travel a long way in your home but aren’t quick, while 6GHz is blisteringly fast, but can be defeated by a sturdy brick wall. A lot of WiFi-enabled gear, like a lot of smart home products, only use 2.4GHz because the range is better and it’s a lot cheaper. But it means that the band is also overcrowded and slow.
Linksys’ CEO Jonathan Bettino told Engadget why mesh systems are an “advancement in WiFi technology” over buying a single point router. With one transmitter, the signal can degrade the further away from the router you go, or the local environment isn’t ideal. “You can have a small [home], but there’s thick walls [...] or things in the way that just interfere with your wireless signal,” he said.
Historically, the solution to a home’s WiFi dead zone was to buy a WiFi Range Extender but Bettino said the hardware has both a “terrible user experience” and one of the highest return rates of any consumer electronics product. Mesh WiFi, by comparison, offers “multiple nodes that can be placed anywhere in your home,” says Bettino, resulting in “ubiquitous WiFi” that feels as if you have a “router in every room.”
Having a “router in every room” is the biggest selling point for mesh WiFi given how reliant we all are on the internet. Each node is in constant contact with each other, broadcasting a single, seamless network to all of your devices. There’s no separate network for the 2.4GHz and 5GHz bands, just a single name that you connect to.
What to look for
It’s a pretty good time to buy a mesh WiFi system, since WiFi 6E represents a fairly significant leap in the technology. Matt MacPherson, Cisco’s Chief Technology Officer for Wireless, said that WiFi 6E is a substantial “inflection point” and can take advantage of a much broader chunk of the wireless spectrum than its predecessors. “If you’re using that spectrum with a WiFi 6 [device],” he said, “you’re going to get significant gains [in speed.]”
MacPherson added that WiFi 6E will likely “carry you for a long time,” thanks to the fact that its “top throughputs now typically exceed what people can actually connect their home to.” In short, with a top theoretical per-stream speed of 1.2 Gbps, WiFi 6E is fast enough to outrun all but the fastest internet connection. (You may also see talk of WiFi 7 devices, some of which have been released already before the standard is officially launched next year. Given that it will take a generation for all of the devices in your home to be compatible with WiFi 7, it’s not worth thinking about this for several years yet.)
Range and speed
Every mesh product will boast of its theoretical broadcast range in square feet, as well as its theoretical top speed. Given there are so many factors outside of the manufacturer’s control, these numbers don’t really mean much in the real world. Your internet provider’s real speed, the construction materials and layout of your home, amongst other things, will all affect your WiFi.
It’s worth saying that raw speed isn’t everything, and that for most normal users, you probably need a lot less than you’re paying for. Netflix recommends a minimum speed of just 15 Mbps to stream a 4K video to a single device. Naturally, that’s just for one connection, so you’ll need some more capacity if you’ve got other devices all running at the same time. As cool as it is to say you’ve got 100, 200 or 500 Mbps download speed, factors like latency and reliability are way more crucial.
