We need to move our desktop computer into a different room from where the hub is connected to the virgin box. Our desktop is is wired to our hub and we can’t drill through our really thick walls. We’ve already got a WiFi booster so I’m not able to order another one via the app. The app says to ring 150 and when I do I keep being told everyone is busy and to use the website. Well the website is crap and doesn’t have the information or answers I need.
what specifically are you wanting? are you wanting another booster (bad option IMO)? you've already said you have really thick walls, so you really need powerline adaptors, which you can buy much better ones that what virgin would supply to you.
