Virgin Media has a rubbish wifi and J should contact technical support everyday and submitted a compliant.
When I had contract with Vidafone and TalkTalk I never contacted technical team and have the same number of devices connected with the router but never had any problem. I see Virgin Media clearly stolen my money with it is rubbish broadband service
VM (& all other BB providers) provide a service that is guaranteed TO the Hub and what comes out from it on an ethernet cabled device. Their T&C's all expressly exclude guaranteeing wifi connections - as it is so influenced by the external environment.
Even BT with its glossy ad's saying wifi is “guaranteed”, also charge £10/month for that and say that if it isn’t sorted they will just give you £100 back. VM try and help by swapping the Hub (just in case!) and providing Pods - at £5/mo, but the reality is, that if the Hub wifi doesnt work well for you then you are far better sourcing your own wireless equipment.
You could try separating the SSID's of the 2.4 and 5 GHz wifi bands and switching off "channel optimisation" - that often helps Hub3 users get better wifi performance - but its still no substitute for better kit.
