Hi my broadband drops out when I receive a call. Can anyone help...
if you use filters then try and replace with new one
if filtered master socket then try connecting to test socket with filter and see if that stops it happening
This guide shoul help https://www.bt.com/help/broadband/why-do-i-need-adsl-filters--microfilters--and-where-do-they-go-
It also applies to FTTC "fibre" broadband.
