2.4GHz or 5GHz? What's the difference?
Your router has two Wi-Fi bands and they're both good at different things.
Think of them as two runners. 5GHz is the sprinter. Quick off the mark and better over shorter distances.
2.4GHz is the marathon runner. Not quite as speedy, but it goes further and handles walls a little better.
The good news? You don't usually need to worry about choosing between them. Your router and devices generally sort that out for you.
But sometimes, a gadget needs a little help. Some smart home devices, like doorbell cameras and older bits of tech, only support 2.4GHz. Which might explain why something's refusing to connect.
And if that's happening, we've got you covered. You can set up a separate Wi-Fi network yourself through the GoFibre app if you've got one of our Standard or Advanced routers.
And if you'd rather leave the technical bits to us, that's okay too, give our lovely Customer Support team a call on 0800 059 0980. They can sort it remotely, so you don't have to fiddle with any settings.
