    Hii... i have a macbook pro with leopard, and it has the 802.11n card.
    The internet works perfectly at home, but then i tried using the school wifi and i could connect to the network itself but then neitehr safari or firefox could get on the net. i opened network prefs and it said i have a self assigned ip and i may not be able to connect. my friend with a 802.11n macbook could get wifi working ... so why can't I?

    a macbook has a way stronger wireless signal due to the plastic casing. try going somewhere, where you know you have a super-strong signal from the school wifi.
    if it still doesn't work, try creating a new user and trying it with that.
    if it sitll doesn't call apple and make their ears bleed about it.

    Try restarting your computer while it's under that wireless. I was at a friend's house yesterday and had the same problem getting onto his wireless network. I was able to connect after a restart.

    i know my school requires you to register your computer with them before you can use the network. maybe check your schools policy.

    You didn't say if your friend attends the same school.

    Many schools use 802.1X WEP security on their Wi-Fi networks to ensure that only authorized personnel (e.g., students, faculty) have access to their bandwidth. In addition, it helps them track network usage policy abuses.

    In these cases, the network will usually present itself publicly but will refuse to assign an IP address. This sounds like the issue you are running into.

    Authentication is required, and the format of the credentials varies from school to school, so you'll need to speak with either (a) your student computer services office, or (b) another student who has successfully gotten a laptop authenticated on the campus wireless network.

    there is a problem with the proxy configuration of the network

    i think you will need automatic configuration in what called a pac file.
    it is a url that usually starts with http://wwwcache.xxxx/xxx.pac
    where the xxx could be anything of your university website. (dont try to guess this, ask your it guys for it, it is not a secret)

    once given, go to network connections and choose airport, select proxy tab. Then there is something just below the proxy tab. choose using a pac file and then enter the URL.

    hope this is the solution.

    Hey, yeah he attends the same school.
    it doesnt use any WEP/WPA anything... neither of us have registered our laptops and basically anyone off the street could use the internet here.
