Welcome to the forums and the Virgin Media family 🙂 Thank you for getting in touch, I'm sorry that you've been having issues with your new broadband service.
I've had a look at the connection entering your property and everything looks fine from our end. However, it does look like there might be a couple of devices which are affecting the wireless network in your home. Our diagnostic systems are reporting that you have one or two devices too close to your hub which could be disrupting the production/range or a wireless connection.
Is there anything electrical near your hub which could be moved away, or connected via ethernet in order to reduce the number of queuing requests?
Our WiFiWins should help to further explain this. I know they may seem a little basic but it really can make a lot of difference, there are a lot of factors which can interfere with wifi.
