Hey so my modems Ethernet ports are not both active. I have 2 PCs plugged in and only one is registering a connection even they are both hardwired Ethernet into the same modem. I just got off the phone with Comcast and they said it was a manufacturing issue? Any help and support would be great.

The dual ports are only usable if Comcast sets you up with 2 distinct IP addresses. That is not typically done, and some ISPs bill extra. In most cases, if you want more than one device, you should add a router that will handle DHCP for you. You can’t just plug 2 devices in.
