I am having connection woes. I have a built-in modem-router ARRIS SBG6782-AC and it has served me well for over 4 years. I recently moved across the street (June and since the last 4 months, I am seeing random connection drops, the device rebooting and connection dropping. It happens randomly. Sometimes, it comes back up by itself, other times I need to physically reboot the device and then it comes back up.
Note - I encountered this 3 times while typing this post (15 minutes) (had to type in onenote and then paste it here, lest I lose it)
