I have an Apple Airport Extreme with Wireless.
I cannot tell you how much of a pain it is to even hook up Apple Hardware to it.
Though my Android Phone see's it just fine and connects and uses it perfectly, my daughter's Apple Mac Book Pro, flipping between home and school (school is Windows based kinda stuff) just wreaks havoc for the poor thing. Even with Lion on it.
But, most of the time, once you whaap it a few times it realizes its talking to an Apple router again and magically works.
Now my IBM T61 with Debian Sid on it, has no problems what so ever... I'm using NetworkManager for all my connections (Wireless, Wired, Broadband, CDMA, and VPN over those). It works just fine.
Of course, that is me... not someone else.
