I need to unplug my system everyday to reboot to receive a signal, after I've turned off my tv at night. Just did a troubleshooting test. Comcast says nothing is wrong. Well something is. They also Sent me a new modem a week ago. This has made the reboot an everyday occurrence. Anyone have any answers?
Start here: troubleshooting guide. If you still need help, please post your equipment details (make/model of your modem/gateway/router) and a screenshot of your signal levels and your error/event log. Thank you!
