i have an airport extreme base station and two computers with the extreme card but its not hooked up yet. i would like to know if the WIFI is significantly slower than a wired system. i didnt setup the airport system in my house yet but i didnt install the card into my ibook. the reason i ask is because this one particular cyber cafe that i go to, i tried using their WIFI capabilities and it was really slow. so i tried going wired with an ethernet cable and everything was so much faster.
