red alarm light on ont

[Simpleeeee]

Alarm light is showing solid on ont full fibre box.  internet is working with advertised speed but drops out from time to time.  Fibre was installed approx 3 months ago and alarm light is on now for a couple of weeks.  Ive tried re-starting but it doesnt seem to make any difference.

It could either be a battery back up unit losing charge or a failed ont firmware upgrade

@Simpleeeee 

As @cookiemonsteruk indicates, if you have an early model ONT with a battery backup unit then a red LED on the BBU just indicates it's no longer capable of holding a useful charge: this doesn't actually affect the broadband itself.

The light would be in the middle of the lower right cluster.
