ADSL Business line times out under moderate load

Hi all

 

 

My cousins business ADSL line is very weak.

 

 

 

Under any load that puts a little bit of strain on the line, the latency/ping times goes sky high and then the line times out and the line ends up timing out. 


email and texting is fine, light load doesn’t cause the line to drop out. 

The line is a business connection of 12mbs down and 1 mbs up - so very slow by modern standards but even a moderate load such as FaceTiming or Zoom calls drop out, that should not happen. 

I called BT and they pawned me off saying “you’re getting the stated line speed for your area blah blah there’s nothing wrong with the line go away” 

 

I reiterated that it’s not the speed that’s an issue, the line hits the speed of 12 MBs and then drops out and the connection is unstable. 

There might be corrosion on the line but it’s hard to tell. 

I will replace the filter and use the test port this afternoon to see if that helps, I just need to document this and see if anyone has any suggestions. 

fibre is coming to the area but it’s a very remote part of England and there’s no urgency by the ISPs to spend a lot of money on installing fibre for maybe 20 users, even if that’ll get rid of the ADSL issues. 

if anyone has any ideas beyond replacing the filter and trying the test port, please feel free to say. 

 

I will call the BT support line tonight if I can’t fix it today.

Hi all

 

just did some light browsing of LinkedIn whilst running a speedtest and got these timeouts.
