I do not want to use unauthorized network without permission.  I can ask permission from Administration, but the guy that knows the key is not here.  If there is no way to do it, then I rest my case!  The person can die and then the key is lost to the network.  There has to be a way to do it.  The computer could access the network before. it was set up by wireless dhcp, but now someone who manages the network put a key and many users(teachers) cannot access the internet.  The person that takes care of that is on vacation.  Is there a way or not?

WEP is easily broken in under 5 minutes with the right tools. There are 
plenty of how-to's strewn across the net. WPA is another matter as far 
as I know. The last time I looked it was brute-force only, which means 
dictionary attack which of course assumes that the password is in the 
dictionary. WPA is weird, it can be easy or near impossible to break 
depends on how strong a passphrase was used, is there a RADIUS server?. 
WPA is generally very difficult if the admin has enough sense to use a 
long and truly random passphrase but admins like that are in short 
supply. If you really want to know google will throw up many links to 
info. There may be a tool by now that makes short work of WPA . You can 
get in trouble for trying to break into a network, the right person has 
to give permission before you can even try. Careful I don't want to see 
you on CNN unless your promoting free software :^) In any case you will 
need a wireless card that can be put in monitor mode to capture the 
necessary traffic, not all cards support this, if you can't put your 
card into monitor mode then don't bother. Google can give you more 
specifics if you really want them.
