Welcome to our forums and thank you for reaching out with your concerns. I'm really sorry that you've been having trouble with your new services.
First of all, I'd like you to try manually connecting to our network by following these steps: press Home on your remote > select Help & Settings > select Settings > select Network > select Connect to the Virgin Media Service now.
However, in taking a look at the backend of your services, I can see that the levels entering your property aren't as expected. This may account for the issues you've been experiencing. We'd need to get an engineer out to look into this for you, so I'll send you a private message now to clear security. Please head to the purple envelope in the top right corner to respond.
I'm glad that this appears to be working for you now 🙂 Your equipment is still reporting low power levels, so I'd recommend having an engineer to resolve this before it starts to cause further problems.
I've sent you a message, so please drop me a reply when you're able and we'll take it from there.
