My modem is going out. I was on the phone with a t & t for over an hour and they wanted to ship me one of theirs. Grrrr. Can you guys tell me which dsl modem is the best one to buy? I know that some dsl modems work better with mac computers than others. I have only mac computers. I don't have airport extreme, or express, etc. Another question I have is, what is the benefit of purchasing Airport Extreme or Airport express? I've just always used the wireless connections I have had from my dsl router. Thanks!
