Trying to diagnose the cause of regular "DSL link down" events

robers7 — Sun, 22 Aug 2021 19:12:42 GMT

I've been getting DSL link down for about 2-3mins at a time increasingly frequently. My G.Fast line was installed about 18 months ago (I am less than 50m from the cabinet) with no problems initially. In the last 4 months I have been having DSL link down starting at once per fortnight, then weekly and now every 3 or 4 days (sometimes more frequently).

The timing of the link down does not seem to be at any particular time of day. Predominantly it happens during daytime, but two or three drops have taken place in the middle of the night.

My Home Hub stats are below. Any thoughts? Could it be an interfering device in the home? (not sure which one though..)

Have you tried the first, simplest quiet line test? 17070 option 2, best with corded phone.

Thanks for the reply. I did the silent line test - heard nothing. Repeated at various times of day too.

At a bit of a loss to be honest.
