A device supporting WiFi 5 can take advantage of a WiFi 6 router.
A device supporting WiFi 5 can take advantage of a WiFi 6 router.
The article from smallnetbuilder.com was published last October but remains useful today. The distinction between AX and AC isn't as significant now, though AX still offers some benefits. Not all client devices can fully utilize AX, and not every WiFi 6 router supports its full range of features at the moment. Since the standards are still being developed, it's not wise to invest in a WiFi 6 router hoping it will be ready soon. Unless you need a faster router and it meets AX requirements, it may not be worth the wait.
The greatest advancement will come from WiFi 6e, offering numerous additional channels within the 6GHz spectrum. This shorter range compared to 5GHz should help reduce interference. Many users may be dissatisfied, requiring more access points inside homes, but it’s the only way to boost WiFi performance in crowded spaces.
