Re: LOS Light is red

I assume that you are on FTTP?

 

LOS= Loss of signal.

 

Most likely a fibre fault somewhere, or possibly a fibre modem fault.

Make sure that the fibre going into the modem is not been bent or damaged, and that the connector has not come loose.

 

All you can do is to report it as a fault.

It would be best to arrange a visit from Openreach, via the FTTP fault number.

I am not sure whay you mean by "yellow stuff"

Right, not so familiar with FTTP, but I'd go with Keith's advice.

Re: LOS Light is red

hey Keith

i think that person you were talking to was talking about the small yellow cable that connects to the right side when looking behind the router.

my router also doesn't work by having that red light on the "LOS" bar.

i went all over the internet for help and the most helpful and common way to fix it is to get their services help. but im here to get help first.

You cannot fix it yourself, all you can do is report the fault.
