Ethernet not working from modem
Hello! I've recently noticed my PC desktop isn't getting a signal via the ethernet cable running between it and my router/modem. It's worked in the past, and said desktop is still getting WIFi (as are the rest of my devices in my home). I've restarted the modem and also replaced the cable to no avail. Also worth noting is the fact that all 4 ethernet ports on the back of my router are now glowing orange - one is also flashing. This is new. LIke I said, I'm getting internet but it's not going through the ethernet cable for some reason. I've tried troubleshooting with no luck as well. Not sure if the problem is with the modem, my computer, or something else entirely. Any help appreciated!
Modem: Zoom 5350 (Series 1092)
