Just another point...
Every single device connected to any phone socket needs to be filtered.
The filter should plug in before ANYTHING else. So exactly like this
See phone socket - filter - telephone or sky box
See there are 4 sockets in use. At each socket a filter is used before the other devices.
If one device was connected WITHOUT a filter, this would cause massive issues. Say a landline plugged straight into the socket without a filter...
So you need to ensure that your devices are all filtered too
The downside to this example is the modem isn't in the master socket. BUT it really should be. So move your router down to the BT socket like I've said before.
This is a bad example
Notice that there is a splitter connected BEFORE the filter.
The filter needs to be the FIRST device connected to every socket.
EDIT: Can you give us stats in the BT socket as well please.
