if you have a static IP at uni instead of DHCP, you're going to like hpc netprofiles then
(it is not required but much more comfy than manually adjusting...
)
if that's not the case
(that is, you have DHCP at uni - makes things easier..
), simply create a new profile in your config utility for the wlan card. one for the uni another for hotspots and this one should have no WEP no nothing.
hmm you mention userID and password network authetication... maybe that needs to be turned off too before using the card in a hotspot.
edit: i tried to IM you on yahoo.. you weren't there
(i'll reply to your email soon!
)
