You would probably be better of investing in a decent third party router, that way you can put the Virgin Hub into modem mode and let the router deal with all the traffic. This would give you better wi-fi coverage and if you go for the likes of a wi-fi 6 capable router you would get better speeds if you ever upgrade you line speed. There are loads of options from Asus, TP Link etc and seeing as the VM Hubs are well known for their lack of wi-fi capabilities you would be better of using your own equipment, especially if you are suffering from poor wi-fi coverage and speed.
