Sometime today all my network lan lines are dead. The only internet connection I seem to have is if I use one of the two (2.4 or 5) wifi network connections that are part of my Comcast Cable modem. My router seems to be non-existent, though it's lit up and everything looks good on the device's LEDs. I cannot connect ot it or any of my routers/access points.
I saw a Comcast repair person getting ready to climb a pole in my neighborhood, is this something that's likely their doing? I have done nothing to my network or devices.
Update: After a couple hours of troubleshooting I found the problem and fixed it. It was not Comcast's fault at all. It was my own fault. I had moved a pelican case under my desk, which was pressing against the ethernet cable connector at my wall drop. The network connection downstream was restored as soon as I unplugged and reinserted the cable connector. Thank you, everyone for the replies.
