Weird Airport Question....

I have a Macbook and my g/f has a MBP (lucky her!) BUT, when we are at the same places...sometimes my Airport will bypass other WiFi's passwords and hers will not.....it actually did that on my iBook too......

It doesn't do it all the time, but it seems on the same WiFi spots that are password protected, my MB will get online and hers won't.

Just curious what could be causing that? Maybe my MB is stealth MB?

Why, can I ask, are you complaining? You are getting free internet aren't you?

Do you hear me complaining? I was asking what would cause that....just seems weird is all.
