Cable Modem rebooting in the middle of the day causing 5 minute outages
Hello,
My cable modem, Arris SB 6183, reboots almost every single day and causes a 5 minute outage in my internet connection. When this occurs, I see the following error in the cable modem logs.

Hello, I hope overall your weekend has been a good one. I am sorry this intermittent connectivity is hindering your online experience. I know you need a stable connection to get things done and your business depends on this. I promise I will take the right actions to help as this is the right team to help. Are you able to send a private message so I can locate your account? If you can include your name exactly as it appears on your account, your full-service address, and your account number? (or phone number) this would be perfect.
