Starting today, my router now only shows solid RED lights and Network Status page says: poor network. Odd since I didn't get an outage alert. Investigating further all wired and wireless clients are fine. No issues with accessing the internet. Going further,I ran a speed test and get above my advertised speed at around 2.2Gbps. 

TP-Link ID page incorrectly says: 

"Oops...

The device is offline. Please check the WAN and network configuration to make sure the appropriate settings are entered correctly."

So perhaps its trying to get to a remote resource thats offline? 

EDIT:

I changed from my ISP dynamically assigned DNS to Google, and it went BLUE.

Next I tried AdGuard DNS- this also causes the lights to show BLUE.

So apparently whatever domains/IPs TP-Link is using on the router to determine connectivity is not jiving with my ISP's DNS? I find this odd. Why would this be?
