Storm Dennis and my Fibre connection

[#1]

During storm Dennis on Saturday and Sunday my router was losing connection every few minutes. I called and logged a fault ref no, 199050870

I have overhead lines from the cab which pass through trees and I am assuming that as they were being whipped about by the wind this was the source of the problem because on Monday when everything calmed down the connection stabilised.

At the moment the connection has been stable (no drops) for more that 24 hours:

However my connection is below minimum guarenteed speed due to the DLM having a nervous breakdown.

These are my router Stats:

The normal data rate before Dennis was about 27mB.

I called the helpdesk yesterday and they said there was still a fault on my line, but if there is its not showing on my line stats. The errors are not increasing. Only fault at the moment sems to be the DLM, happy that it has restored stability, is resting on its laurals and not wanting to increase my line speed.

Can a PN staffer please advise if the Friday appointment should be cancelled (I don't want a no-fault callout charge thank you) and if so can a reset of the DLM errors be requested so I don't have to wait weeks for the DLM algorithm to relax and restore normal operation.

Many thanks

Still up - any comment from PN?

That didn't seem to work, try:

Well, there's a strong and gusty wind blowing this morning and the connection is dropping out again every few minutes so I assume storm Dennis did some damage to the overhead wires.

When a gust blows I can hear a lot of noise on the line during a quiet line test so I hope the wind is blowing when Mr O/R comes tomorrow...

So Mr Openreach turned up today and as expected no wind so no line drops.

However he didn't just leave with a no fault found but went out and checked my overhead wires.

After an hour or two he found a place in my neighbour's garden where the line was hooked up on a tree and the wire inside the insulation was broken, but mostly still making contact except when the line moved about a lot.

After replacing the wire he reset the DLM and all is now fine, I'm getting over 29Mb which is about the maximum possible so I am very happy.

Well done to him for getting stuck in to find the fault instead of walking away.
