Hyperoptic — smart-home gadget keeps going offline

Hyperoptic: why does my smart-home gadget keep going offline?

The short answer

Most smart-home kit uses only the slower 2.4 GHz band and needs to be on the same network as your phone. The usual causes are a guest network, a separate 'IoT' network, two different Wi-Fi names, or a router that filters the background chatter these gadgets use to announce themselves.

The short answer

  • Most smart-home kit uses only the slower 2.4 GHz band and needs to be on the same network as your phone. The usual causes are a guest network, a separate 'IoT' network, two different Wi-Fi names, or a router that filters the background chatter these gadgets use to announce themselves.

Is it the line or the Wi-Fi?

  • Test wired next to the router
  • Test in the room that struggles
  • Write both numbers down with the time

Free things to try first

  • Put your phone and the gadget on the same Wi-Fi name — Not the guest network, not a separate 5 GHz name.
  • Turn off client or AP isolation — This setting stops devices seeing each other, which breaks most smart-home apps.
  • Turn on multicast / mDNS forwarding if your router has it — It is the background chatter speakers and cameras rely on.

Where Hyperoptic fits in

  • Hyperoptic is a "Basic router" provider in our comparison, scoring 27/100 for the Wi-Fi support they actually give you.
  • No Hyperoptic Wi-Fi app at all; many customers end up buying their own mesh.
  • Take dated evidence with you — it changes how the call goes.

If it is not fixed

  • Ask for a formal complaint reference
  • Six weeks unresolved, or a deadlock letter, opens the free independent route

People also ask

  • Is this a Hyperoptic fault or my Wi-Fi?
  • How do I report this to Hyperoptic?
  • Will a Hyperoptic engineer visit help?
  • Can I use my own router with Hyperoptic?

If you do end up spending money

Only after the free fixes. Nobody pays to appear here, and no shop link changes anything we say.

  • Mesh or a wired second point — only after the free fixes
  • Managed Wi-Fi, where the provider owns the fix instead of you
