Welcome to the Community!
For customers experiencing any issues with their service, we recommend the best thing to do first is check if there's an outage.
Based on the account I've managed to locate using your Community details, your modem is connected for almost 2 weeks now which is an indication of a stable connection.
Rebooting the modem is one of the basic troubleshooting for most internet problems. Modems are like any other electronic devices, it is not built to be running at all times. One of the reasons why we advise this is that when you leave your modem on for too long, it will tend to stop performing at its best.
