Our BT line was Noisy (Static) expecially when the weather changed. So the internet was very often on-off-on-off .....
But worse - the router would splash audable network and dialup noise onto any phone call so we had to turn it off while making calls.
Browsing various forums suggested that the filters (dead or dying)) and maybe router (capacitor noise) needed upgrading....and our line needed checking.
BT man came and checked all the connections from Grren box to our house and replaced a small section of Al wire. Noisy line now much better.
More intresting is that there is now no audible noise from the router while making calls. (Router and filters had not been changed)
So when you have network noise while making a phone call - It may not be filters at fault.
