Wi-Fi 5 vs. Wi-Fi 6: Is there a practical difference?

Technical Difference in Brief

Wi-Fi 6 (802.11ax) is newer than Wi-Fi 5 (802.11ac) — offering higher theoretical speeds and better performance when many devices are connected simultaneously to the same network.

When the Difference is Noticeable

In heavily loaded networks (an office with many connected devices, public places), Wi-Fi 6 is more stable. For transferring large files over the network, it also provides a speed boost if you have a compatible router.

When There's Almost No Difference

For a home network with a few devices, regular browsing, and video calls — Wi-Fi 5 is perfectly adequate, and the difference is unnoticeable in daily use.

Important Condition

The advantage of Wi-Fi 6 is only realized if the router also supports this standard — with an older Wi-Fi 5 router, there will be no difference at all.

Can the Wi-Fi Module Be Replaced Separately?

In many business models, yes, the network card is a separate, replaceable module (more details in a separate article on Wi-Fi/BT network cards), which allows for an upgrade without replacing the entire laptop.
