I have a problem with my phone and BB when used together. I use a netgear DG 834G router ethernet wired with the wireless disabled, my problem is that I also use a Panasonic DECT phone and a normal wired house phone. On the DECT phone the sound is clouded by a background hiss which at times is quite annoying, on the other hand there is no problem with the house phone, when I turn the router off the problem goes away. I have tried another netgear router but it makes no difference to the hiss problem. I have replaced all filters and the base unit for the DECT is well away downstairs from the router.
Some help and advise please
