Can I extend the range of my Yahoo/SBC DSL wifi modem by adding some kind of "repeater"?

IF possible, move the wi-fi router to the center of the house && as high as possible. House building materials, furniture, appliances, even plumbing/electric wiring block wi-fi signals.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
