Right tech has been, was the same person as last time. He could immediately see there was a problem as his PDA was showing a fail on the upstream test. He could also see that the downstream SNR was low. Went off to the cabinet and adjusted the upstream there. So thats been lowered but he still wasn't happy with the downstream SNR. Rang up the same people who gave the CARDIE reading before and they said it was fine. I don't think he was convinced, so he rang networks and passed it on to them. They are going to monitor it over the next few days and the tech is going to call me back on Thursday. Stats are currently:

Hopefully networks find something but I'm not overly convinced they'll sort it.

Does the fact that one of the upstream values ending in .x6 mean anything? I thought that the value incremented in .25 steps. I wonder if it's worth asking the lady I'm dealing with on the VM forum to perhaps send out another Superhub, just to rule it out.
