AX5400 (AX73) WAN port suddenly non-functional
This router has been running with no issues and no changes for the last 3 months.
Suddenly the other day the internet stopped working. ?? The cable modem link lights are all on, including the link to the ax73. But there's an orange light on the ax73 wan port (that goes to the cable modem). I log into the ax73 interface and see:
"TP-LINK AX5400 - NO INTERNET CONNECTION - Something's wrong with the hardware connection".
I've rebooted this device 3 times now, including pulling power and letting it sit that way for 10 minutes before powering back up. I've done the same with the cable modem. I then swapped ethernet cables to a known-good cable. I'm on the latest firmware.
Still have the orange light on the WAN port, and the same error message.
What can I do next? I need the internet for remote work and for my kid to do school.
Thanks!
