Comcast internet modem
Comcast wants us to get a new modem anyone else get that email? What's up with that? Mine works good. Option to buy or rent. Comcast is known to charge people for rent after they bought one. It's hell...

If anyone has Modem that keeps rebooting check the upstream power levels. They should all be under 50. If they are 54 or higher you will get port shutdowns, and reboots. The problem may be the cable line, or too many splitters, and not the modem.
