xt8 dropping 2.5G wan/reconnect loop

[rni302]

I searched for this and did not find any obvious answers.

I have a new XT8 that was flashed with the latest firmware, connected via 2.5G ethernet to a dedicated pFsense mini-pc with a intel 2.5G port

While I do not see any obvious issues with my internet - i see from my asus logs that there seems to a endless loop of disconnects/reconnects. bad cable?

Those messages almost always indicate a cable fault or other hardware issue.

I had 3ft of cat5e cable, I guess it was not good enough (despite many online sites saying 5e is just fine for > 1G)
I just got a new cat6a cable and the errors have not re-appeared since.
