Does anyone have an updated source of these filters as I suspect the filter I have at home is on the way out. Intermittently there is noise on the fone line. When I unplug the ADSL router it goes away. Have tried with two different routers. Also I have been getting frequent BB disconnections since Sunday which I now put down to this as when it resets it's self the speed drops from 3.5meg to 1 meg untill the router is repowered.
Thanx in advance.
