I have had an issue since upgrading to 6.15 when my router stops authenticating on the PPPoE interface. All i get is link established, rebooting or downgrading software does not resolve issue. Reset of router back to factory allows internet access again.
I have lodge a ticket re this but was hoping someone else might have had come across this before.
thanks for the suggestion, i have tried removing the interface and re-adding but issue still happens, seems to be only fixed with a complete reset of device and set up. I have upgraded to 6.17 so hopefully it was just a glitch as we have 100’s of these routers with clients on 6.15
