Upstream power levels are too high, all other stats are fine. You need technician to visit to rectify. Call customer services and report the problem. The logs do not indicate a router firmware upgrade.
There are 10 types of people: those who understand binary and those who don't and F people out of 10 who do not understand hexadecimal
Your upstream power levels are still at max transmit and need VM to take a closer look.
The logs are showing occasional dropouts of VM's connection, but not several times a day, so you may have a wireless dropout problem as well. Do wired devices dropout at the same time, or does the Hub's lights change behaviour.
Due to the poor service you have received from the call centre, I would wait for a Forum Team member to pick up the thread and arrange for a closer inspection of your connection, or you could try ringing again and hope you get a better agent.
