why does the internet go down whenever the phone iis in use?

[almoststew1990]

As title really. Whenever the phone rings or someone dials, the internet goes down- I get a message from my router saying Can't Connect to Broadband. I have BT total broadband (not fibreoptic) and a BT HomeHub 3. I have a ADSL filter already.

A filter on every phone? Even though there won't be an Adel cable using it? Interesting because the phone we use the most is in the room without the filter.

Seems kind of obvious really. I might replace the 10+ year old filter on phone 1 too

Thqnks for the advice!
