Frequent connection drops everyday, modem says T3 or T4 error
I’m having frequent internet connectivity drops every day always late morning/early afternoon (usually between 11:00am and 1:00pm) but also randomly throughout the day. I first got a new modem from Spectrum which didn’t change anything so I scheduled a service appointment. A tech came out replaced an old splitter and checked the signals said they were strong; he couldn’t find line damage but I don’t know how thoroughly he looked and the problem is exactly the same. I bought my own modem
to try that, a Netgear CM500, and still the same problem. Both the Spectrum modem and the new Netgear modem show the same thing: T3 and T4 errors whenever the connection drops. At this point I have no idea what’s going on and everyday there is a time when my internet is practically useless. The error log from the Netgear modem is below, I don’t have any saved from when I was using the old Spectrum modem but they look to be similar if not identical error messages.
