I can already see from the Downstream data that there is a problem. The recommended power range is from -6 dBmV to +10 dBmV and several of your channels are well below this range. Probably as a result of this you are getting an awful lot of post-RS errors when there should be none. The signal to noise ratio should be at least 34.5db, the higher the better, but many of your channels are way below this indicating a noisy connection. It also looks like only two of the four Upstream channels are active.
In short, this is not a good connection and will require an engineer's visit to sort it out. Possibly something as simple as putting you on a higher power tapping point in the street cabinet will resolve the problem.
In the meantime, just check that your cable connections are secure in the back of the hub and at the wall socket.
Yep, that's a real mess of a set of stats, I would hazard a guess there's a really dodgy cable connection somewhere in the link back to the cabinet. It's very unlikely that checking and tightening the connections on the Hub or wall box will do anything to fix this, but it certainly can't do any harm. You can either call it in as a fault but you might have to jump through a few hoops with the call centre to get them to agree to an engineer visit, or just hold tight for one of the forum team to spot this thread and contact you to arrange something.
There's just a chance that it's actually a dying Hub and it wouldn't surprise me if they swop it out as well.
