The smart switches are under kitchen cabinets and control lights using Alex's. I say lights on and the counter lights come on except mostly now they don't which means crawling dismantling and reconfigure ing them to the same virgin hub again then they might work for a bit same as my phones.
The extender I bought as the virgin hub does not reach either my bedroom or other room from the lounge where the hub is next to the TV as that is where the cable comes in the house not central so can't be moved. I have run lan cables up to the spare room for home office. Yesterday the TV which is 3ft from hub on 10ft cable said no cable connection. I unplugged and replaced mtuple times it said connected but then when I went to utube said no connection check cable. I reset the hub to clear it. Not ideal when one of us is working g from home.
The hub has never reached 40% of the house. Where a bt hub upstairs used to.
The smartplugs and extender used to work fine until I renewed my contract in August. No equipment was renewed but I did drop virgin TV as I couldn't afford the cost.
Other companies offer the same deal and speeds now the street has fibre to it.
My phone is connected OK right now but I know later it won't. And the kitchen lights won't work too.
Alexa rarely can't connect but mostly does.
Either something was changed your end when I renewed or the hub isn't as powerful as it should be or it is faulty. The hub is in the open above house radiator height no other interference nearby.
It isn't my phone as the iPhone have same trouble.
I have reset hub a few times only changing password and name to something we all remember.
If it was a setting then it would be all the time.
The extender has a same name but with ext on the end so we know what we connect to which seems to stay connected. So when we can't connect to virgin hub WiFi on full bars we still might on the 'wifiext' even though it is almost out of range where we are stood.
It really is driving me mad and wishing we had gone to a rival that has a stronger wifi
