I have a Balance 20 that has been working flawlessly for over a year and then a few weeks ago, WAN2 started reporting link down repeatedly then it will stop. A few days later it does the same thing again. Over the weekend it now says No Cable Detected.
I tested the cable and replaced both ends and cable tester reports it’s good. What I haven’t done is reboot the B20. I also plugged the other Ethernet cable into another switch and I see the link light up.
Any other way to check if the WAN port is indeed dead?
Thanks!
