You might want to look into a new router designed to manage more than a few devices. I purchased a Netgear Nighthawk router about 3 months ago, having run the Superhub 3 for several years. Both the Network router and the supporting software (including an iOS app) give the user choices about how to set up your home network to accommodate multiple devices. Before buying anything, I recommend you so some research including reading reviews on this site and a broader search of computing review publications such as techradar or pcworld.
To run a third-party router on the Virginmedia service you need to switch your Superhub to a modem-only mode. Search for modem mode in this forum; there are some very helpful emails about what settings to use and how to sequence your connection.
Good luck and please do revisit this forum to let us know how you are getting on.
