Orange Light Flashes On Router

[#1]

Hi

I had a problem with my phone line back in November 2020 after a few weeks the problem was fixed after a engineer came to check my line and found the problem to be outside my home in the street due to a loose cable joint.

Everything has been working fine up until Sunday 10th January when we had a phone call via the landline and the orange light on the router starts to flash.

It happened again today.

Any ideas as why this has started again?

Two suggestions:

1. Your fault has returned.

2. You have a faulty phone or filter, have you tried another?

Hi

The phone is brand new and the filter has been changed.

Was told by engineer in November there was no problem with the broadband.
