I am looking at buying my first router & modem and am curious on what i need to know before purchasing to make sure it will meet my needs. I have a mac pro laptop and desktop and want to make sure i have something compatible so that i can reach each mac wirelessly. I will also be using it for my xbox and want to make sure i have no issues there. And as with anything, the more affordable -- the better! If anyone has any suggestions on what to buy that would be appreciated!
