At this point, I'm guessing that the thunderstorm from the other night broke my original modem, and the surge went to my router, ruining the ethernet port that connects the modem to router. I'm not sure what else to diagnose at this point or even how to.
Not sure if that makes sense but I'll try and provide a detailed description in case an admin sees while I'm asleep. Thunderstorm, modem made a pop, R2 lost connectivity. Tested modem ports direct to PC, one port did not work, the other worked slowly. Connecting them to R2 resulted in the modem not showing lights on ethernet ports and R2 saying no internet connection. Today, recieved new modem. Internet works direct from modem to PC. Modem -> R2 does not work. No lights on ethernet ports and R2 doesn't detect internet connection. Factory reset R2 with button and through the firmware. Ensured DHCP is enabled, I've tried disabling IPv6. Ran ipconfig, flushed DNS, yet I can't get modem to send data to R2.
I appreciate the support! It's an awesome product, just hoping electricity didn't make it past my surge protector and ruin the router.
