That validates the description of the problem's you're having, and shows that the hub is struggling to maintain communication with the street cabinet. If you post the data in the Downstream and Upstream tabs as well, we might (and might not) be able to be more specific about the cause.
Ahh your earlier images have been approved, and your downstream power levels are far too high, and there's a noise issue on the upstream that's causing the hub to drop the modulation levels to 4 x 16 QAM.
Wait for the forum staff to pick this up and advise - could be an area problem with a resolution date, if not then it'll need a technician visit. They can arrange that, and you don't then need to deal with VM's incompetent offshore call centre.
I have been able to locate your account and can see that there is an issue with your downstream power on all of the channels that the hub uses.
I will need to book a technician for you but first I need to send you a private message so that we clear account security with you and then get the tech appointment booked for you. I will send over a message to you right now, please respond with your details and we can get started.
