Prior to the naming convention applied to Wi-Fi 6, Wi-Fi protocols were typically distinguished with the number 802.11, followed by letters to indicate which generation. Under this system, Wi-Fi 6 is called 802.11ax, and Wi-Fi 5 is 802.11ac. In general, each successive generation has been faster than the last, but that’s not all — more security features tend to come with them, as well as improvements in the standard that can lead to more stability and better overall performance. Wi-Fi 6, then, is an improvement on Wi-Fi 5, particularly as it pertains to security and wireless interference. Wi-Fi 6E is actually just Wi-Fi 6, but operating on the 6GHz band. This higher frequency band means not just a bigger pipe through which to shove data, but also very, very little interference, as it’s a largely-unused band that has far more space to fill up. You can think of it this way: If the 2.4GHz band is a 40-mile-per-hour country road, then 5GHz is a 70-mile-per-hour 4-lane highway, and 6GHz is like a 26-lane mega highway. It can accommodate more devices and more simultaneous traffic, at faster speeds. There are other benefits too, but that’s the gist. Faster, more secure. Most new phones, computers, and gaming devices have Wi-Fi 6 capability, but you still aren’t seeing it much on other Wi-Fi devices, and Wi-Fi 6E has seen slower adoption, still — only the priciest phones and laptops tend to get it — so I wouldn’t be too concerned yet about getting a Wi-Fi 6E router unless you really want to be on the bleeding edge.
