Frequent daily intermittent broadband disconnection

Since last november our BT Halo 1 broadband has been randomly dropping connection following an electrical storm, it happens randomly and can be up to 20 times a day and with 2 kids at home trying to do online school lessons its just a nightmare. We have been sent a 4G mini hub but its not really fast enough. 

I have now had a new router and main socket installed and have had 5 engineer visits up to now and the fault still persists exactly as before, i am convinced the fault lies somewhere along the copper line outside our house that runs to the cabinet, the fault usually occurs in wet and windy weather!

I just dont feel im getting the help required to rectify the fault from BT, another engineer was meant to attend this morning but openreach say "Engineer Visit Complete" on the fault tracking through BT support but no one has been to the house.

Any noise on your line?

17070 option 2 best with corded phone. It should be silent between announcements.

I have done the noise test with a corded phone, there is slight noise but not every time I’ve run it

As I’ve typed that last post the broadband happened to disconnect, I have just ran the test again and there was a lot of crackling

Re: Frequent daily intermittent broadband disconnection

if there is that much noise then report a phone fault to 151

Hi @RobPark  and welcome.

Thanks for posting. Sound advice here from both @imjolly and @pippincp . If there's noise on the line you need to report a line fault to 151. Let us know how you get on.
