Why won't my eufy security camera join my 5 GHz Wi-Fi?

The short answer

Only a few newer models use the faster band. Plenty of smart-home kit is deliberately built for the slower, longer-range band only. It isn't broken and it isn't out of date — it just cannot see a 5 GHz-only name.

What's happening underneath

Most outdoor models are 2.4 GHz only; newer indoor and wired models add 5 GHz.

Try these, in this order

• • Put your phone on the same Wi-Fi name as the homebase, not the guest network.
• • Plug the homebase into the router with a cable if it sits close by.
• • Turn off 'client isolation' or 'AP isolation' on the router.
• • Use one Wi-Fi name for both bands rather than two separate names.
• • Check the signal where the gadget actually lives, not where you're standing.
• • Move the router off the floor and out of any cupboard before buying anything.
• • Put the gadget and your phone on the same Wi-Fi name.

Setting it up again properly

• • Stand next to your router while you set it up, then move the gadget to where it lives.
• • Put your phone on the 2.4 GHz network name for the setup, or use one name for both bands so the phone can follow.
• • If your router splits bands into two names, turn the 5 GHz one off for five minutes rather than fighting it.
• • Turn mobile data off on your phone during setup — some apps quietly use it and never find the gadget.

When it's worth spending money

Rarely needed. A cable to the homebase fixes most homes for a few pounds.
