YOU may have noticed a tiny number next to the Wi-Fi icon on your mobile and wondered what it actually means.

Well, understanding the figure could make a huge difference to the networks you choose to connect to - and can even be a sign that you're due a router upgrade.

The digit next to the Wi-Fi symbol appears on some Android smartphones, displayed in the top right corner.

And the number actually stands for the generation of Wi-Fi technology your router is at.
