I have a hub 4, and it broadcasts separate 2.4 and 5ghz networks.
Every now and then, but fairly regularly, the 2.4ghz network stops working. The router is still broadcasting it as I can see it as available on my phone/devices, but when I try to connect to it, it fails. Most of my devices that are connected to it, e.g. smart bulbs, alexas, cameras, disconnect and show as not available on their individual apps, but oddly, not everything disconnects. For example right now, one camera, a smart plug and my heating controller are connected (even though some same branded devices are disconnected) and I can access/control them, but everything else shows as disconnected.
There are no issues at all connecting to/accessing the 5ghz network or anything connected to it.
The only way I’m able to resolve this is by going into the admin area of the router, turning off the 2.4ghz network, and turning it back on again. I have in the past tried switching my router off and on, but this causes the router to (very oddly) do some sort of reset where the 5ghz network name is changed to the same as the 2.4ghz name (meaning everything connected to it disconnects), or the passwords to both networks are reset to the original password provided when the router was delivered (meaning everything disconnects). And I have to go into the admin area to sort it.
It’s completely unpredictable. It might not happen for weeks, then happen four times in a single week. It’s most inconvenient when I’m away from home and trying to access my cameras, lights, burglar alarm - like when I’m at my family’s for Christmas as we speak, for example. It also means that my ‘home security’ routines don’t work (eg turning lights on and off, playing music etc) because most of my devices are disconnected.
Any suggestions?
