Edgerouter 4 doesn't allow devices to browse the Internet

I just recently installed an Edgerouter 4. It was working for a week and now, I cannot get any device to connect to the Internet that's connected to the Edgerouter. I used the Basic Setup Wizard. I've updated the firmware to 2.0.6. I've plugged only the PC into Eth2 and also tried Eth3 and Eth4. The computer gets the IPV4 that the router gave it. I can connect to the router. I see that the router is getting a WAN IP on eth0. I see Tx and Rx on that interface. Right now it's at 10.4 Kbps Tx and 6.25 Kbps Rx. It shows connected but it doesn't matter what device I connect up to it--they cannot access the Internet. I've reset the Edgerouter 4 a few times and tried a few different configs in the wizard but everything doesn't get the devices on the Net. I can connect any device directly up to the CABLE modem and get an external IP similar to the WAN IP on eth0 and those devices can browse the Internet. Can you please suggest any other troubleshooting ideas? From the device, I can ping the WAN IP and get 1ms responses. If I try to use the Ping tool, it doesn't have any responses. It just says 0 packets sent and 0 received. Thanks in advance for your help!

Hi Masnrock.  It turned out to be a problem with the coax cable that goes to the modem.  It was slightly damaged and when the Internet usage was up, it would cause the Internet to go down and go offline.  Modem reboots wouldn't fix the problem.  The coax cable was replaced and everything worked fine after that.  It was one of the craziest things I've ever seen with cable Internet.  Thanks for your recommendation.
