Comcast performs unannounced random upgrades to their modems and refuses to establish a consistent schedule whereby their customers (many of my clients) can work around and schedule their BUSINESS activities accordingly. As a result, customers experience EXTREMELY DISRUPTIVE outages during the peak hours of their production. I have pleaded with Comcast to take a more responsible approach like other providers. As a result - YOU SHOULD KNOW - that is important to reboot your Comcast modem once a month. This may be a perceived nuisance, but since it avoids peak production disruption, it's worth it - REBOOT MODEM ONCE A MONTH.
