My router keeps disconnecting from the internet when the phone rings.
I've tried multiple microfilters and it's connected to the master socket.
The line test tool shows there is a problem. What are the best next step steps to take?
I'm sorry to hear this.
I've completed 2 different line tests and both tests haven't detected any faults on the line.
Could you connect the router at the test socket? Do you have a different phone that you could test with?
