WPA2/Enterprise wireless connection

I am at college and the campus-wide wireless network is a WPA2/Enterprise network. It requires login credentials that are the same as the student logins to the school email and other things. My problem is that often times when I open my laptop and connect to this network it prompts me for a login. I have already put in the username and password and it has been stored in the WPA profile for this network. I have checked the profile and the option for always prompting for the password is not enabled. I am a bit hesitant to bring this to the school's help desk because last time i had a problem with connecting on the network they wanted me to reconfigure my whole computer. I have tried deleting the WPA profiles and making a new one and that did not seem to change anything. Is there anything I can do to make the login prompt go away and not bother me anymore?

Same problem here with university wireless network.Using snow lwopard 10.6.8. My profile is set up with my username and password, the "ask for password" box is unchecked, but I still have to enter username and password everytime, even after hbernation. Any fix appreciated.

Has anybody upgrade to Lion? Does it happen again?

MacBook Pro, Lion -- I can connect to WPA Enterprise with PEAP (MSCHAPv2) authentication seamlessly. Problem is after it's is sucessfully connected, it lags a lot. I mean it's almost not working at all.

I've got win xp machine next to my mac and the network works great here on XP. With mac it's very very bad.

You need to allow anonymous PAC provisioning in your 802.1x configuration if you are using EAP-FAST. If are using PEAP, then you may need to make sure your authentication server is using a trusted/signed certificate (those have to be purchased and if they did not purchase it, they are probably not trusted in most of your cases).

To do this,

1. open "Network Preferences"

2. Click the "Advanced" button

3. Navigate to the "802.1X" tab

4. Click your WLAN on the left in the User Profiles Section

5. Click the Authentication method EAP-FAST

6. Click "Configure..." right below it.

7. check the "Allow anonymous PAC provisioning".

8. Reboot your laptop

OR - make sure "Always prompt for password" on the 802.1X screen is not checked.

*all commands are taken from Mac OS X v10.6.8

Most implemetations of the PAC file when using 802.1x are anonmous. Otherwise, an authentation admin would have to keep track of a unique PAC file for every user station that joins the network. That would be crazy and impossible to do in a dynamic environment like a college campus.

I am writing this down to try out when I get back on-campus (just over a week). If this works (sounds like it will) thank you so much for this information!
