When i reboot the router it syncs with a noise margin of 9db as thats what ive set it to (on LLU so can manually configure noise margin). However after a few week without a resync, my noise margin will slowly drop overtime. For example now my noise margin is sitting at around 7db after 20 days without a reysnc and even during the afternoon wont go any higher. If i left it another week or so, the noise margin would be 6db and so on. Just slowly drops and drops over many weeks. If i reboot the router it goes back to 9db with the same sync.
So is it some router bug that slower drops my noise margin? Doesnt effect anything - speeds, errors, sync etc all fine. Just seems odd that it doesnt maintain the same noise margin
