Dynamic Range Window, Unicast Maintenance Errors
I have been having intermittent connection errors for about 9-10 days now, and have contacted customer support a <5 number of times. No one has been able to provide a solution to my problem (I believe it's hardware involved) and I have a maintenance appointment scheduled for July 5th (jesus I know it's crazy with Corona but that's 2 months out). I mainly have these issues at night time/early morning and all devices are affected on the network (wired, wireless). I have checked the coax for corrosion (didn't see any on the surface), bending (good on that), and secured the connections tightly. The modem I am using is 7 days out the box.
The issues I'm showing are the Dynamic Range Window and Unicast Maintenance Errors. Usually the Unicast errors show T3 time-outs, sometimes I get really lucky and pull a T4! Is there anything I can do while I wait 2 months for a technician to come out? Am I allowed to check the box for a splitter/corrosion myself? I saw an XFINITY van outside today and live in an apartment complex, I wouldn't be surprised if other people are having issues with the connection as well.
Attached are event logs I captured earlier. Thank you for your help!
