Unbelievable. I struggled with this the whole day. Checked the ISP status. Thought, it could be overheating (router is in the garage) or bad RJ-45. Had to reboot multiple times today. Never ever I would have guessed it was a firmware issue.
Thank you for writing this blogpost. I just upgraded firmware. So happy when something has an explanation. !
