Community Fibre — smart-home gadget keeps going offline
Community Fibre: 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.
We publish what breaks for that exact combination and what to change.

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 Community Fibre fits in
- Community Fibre is a "Basic router" provider in our comparison, scoring 35/100 for the Wi-Fi support they actually give you.
- Fast line, but the Wi-Fi is handed to the Linksys app — nothing from Community Fibre to manage or measure it.
- 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
