What area do you live? I am near Manotick, Ottawa.
Interesting. I keep hearing murmurs about problems over there being caused by Police/Emergency Services' VHF radio system. 3:25PM might coincide with something getting reset as part of a shift change.
Except in 2 years the only time this has occurred is in the last week.
I would call into Rogers tech support at 3:!5 and hope that you can be on the phone with an agent when this happens again.
I just got off from chatting with them. They would not even discuss this post or the fact there are at least two of us with the same issue. They insist they do not see an issue and the problem must be with my modem. They are sending a tech to replace it tomorrow. I will update after that is complete and the next 3:23pm time hits on Saturday.
The tech was out on Saturday. The tech could see multiple disconnects at various times over the course of the previous week, but no explanation for it was evident to the tech. I made it clear I do not experience any issues with the internet despite being a power user except for this modem reboot issue that occurs only at 3:23 PM. Instead of replacing the modem there was some work outside on the line done. Apparently the signal to noise ratio improved after this. However, the reboot continues to occur at exactly 3:23 PM every day since.
The tech game me his work cell number and I have a call in to see about next steps. I will update again if there is resolution at some point.
