In summary; every time I answer my landline phone, I can hear crackles on the line and the router drop internet connection immediately. This happens during both in-coming and out-going calls. The router is otherwise stable.
I had this issue before and engineers were sent round twice and the problem seemed to have been solved. But it returned about 2 weeks ago.
Solved! Go to Solution.

Yes, I’ve had filters go bad in the past. Does exactly what you describe…..
