YOU may have noticed a tiny number next to the Wi-Fi icon on your mobile and wondered what it actually means. Currently, most Wi-Fi routers offering a decent enough connection should be at Wi-Fi 6. So, if you're connected to a hub and a 7 appears next to the Wi-Fi icon you're in the best possible shape. Wi-Fi 6 supports two frequency bands, and Wi-Fi 7 supports three, meaning there's a lot less congestion for all the devices competing for Wi-Fi signal. Understanding the Wi-Fi number can be helpful when connecting to public Wi-Fi too if you have multiple options available, as you can workout which is most likely to provide you with a stable connection.
