Hi, I was wondering what exactly are DSL filters for? Do I only need one if I also connect a phone to the same jack? For some strange reason, my DSL connection really sucks if I plug in the filter but is almost *perfect* if I take the filter out. I don't really use the phone and if I needed to, I guess I could just unplug the DSL and plug the phone in. So is the DSL filter really needed?!?
Also, can't I just plug my phone into another jack in the house? Why do i need filters on every single jack?
Thanks!
