WI-FI’S WEIRD NAMING SCHEME:

Until recently, Wi-Fi generations were referred to by an arcane naming scheme that required you to understand whether 802.11n was faster than 802.11ac, and whether 802.11ac was faster than 802.11af, and whether any of those names were just made up nonsense. (Answer: sort of.)
To fix that, the Wi-Fi Alliance decided to rename Wi-Fi generations with simple version numbers. So the current generation of Wi-Fi, 802.11ac, turned into Wi-Fi 5. This new generation, previously called 802.11ax, is now Wi-Fi 6.
You probably won’t hear the Wi-Fi 5 name used very much since it’s been around for five years and just got that name in October 2018. For Wi-Fi 6, you might see the 802.11ax name here and there, but companies largely seem to be on board with using the simplified naming scheme.
OKAY, SO HOW FAST IS EACH DEVICE?
Unfortunately, there’s no easy answer here.
At first, Wi-Fi 6 connections aren’t likely to be substantially faster. A single Wi-Fi 6 laptop connected to a Wi-Fi 6 router may only be slightly faster than a single Wi-Fi 5 laptop connected to a Wi-Fi 5 router.
The story starts to change as more and more devices get added onto your network. Where current routers might start to get overwhelmed by requests from a multitude of devices, Wi-Fi 6 routers are designed to more effectively keep all those devices up to date with the data they need.
Each of those devices’ speeds won’t necessarily be faster than what they can reach today on a high-quality network, but they’re more likely to maintain those top speeds even in busier environments. You can imagine this being useful in a home where one person is streaming Netflix, another is playing a game, someone else is video chatting, and a whole bunch of smart gadgets — a door lock, temperature sensors, light switches, and so on — are all checking in at once.
The top speeds of those devices won’t necessarily be boosted, but the speeds you see in typical, daily use likely will get an upgrade.
Exactly how fast that upgrade is, though, will depend on how many devices are on your network and just how demanding those devices are.
