I'm starting to get daily connection drops now that the weather has gotten warmer. I experienced this last summer as well with multiple drops per day, but not every day. Maybe the weather has nothing to do with it.
Arris WBM760 Modem
TP-Link AC1350 Router
Below is from the modem's log. I have no idea what I'm looking at but maybe someone can offer the smallest amount of advice to get me in the right direction.
When the connection drops, I first notice a webpage does not load, then I look at my router and see the orange internet (disconnected) light. But the modem status lights still look normal. Then 2-5 minutes later, the modem reboots. Also I noticed the time on my modem is an hour early if that means anything. I put the modem and router on a different electrical circuit and I get the same issue. Thank you so much, Here's my recent log:
