Thanks for the reply Saffron, I've searched the virgin media forums and the only solution i can find is putting the superhub into modem mode. Unfortunately as other people rely on the WiFi in my house i cant do that.
Do you have any other suggestions? Other than switching provider.
Modem mode means the superhub becomes a modem-only bridge between your internal network and the Virgin network. In other word, it currently acts as a router/rudimentary firewall and WiFi access point. What MrSaffron is suggesting is that you switch the superhub to modem mode and buy your own router/wifi device.
Currently your network looks like this Computer -> Superhub -> Internet. Whereas with the superhub in modem mode, it would look like this Computer -> Router with Wifi -> superhub in modem mode -> Internet.
Also, when you say your internet is bad, are you noticing slow loading pages or sites failing to load, or are just talking about the quality monitor graph? If the latter, then it may not be anything to worry about.
