The problem is that I don't take my laptop with me often to university, so I usually want to connect using my HTC Magic, but I have no clue on how to install the certificate separately on Android, it is always rejected.
If that does not help, then consider uninstalling the Wi Fi netcard.
To gain access to WIFI at university I have to login with my user/pass credentials.
The certificate of their website (the local home page that asks for the credentials) is not recognized as a trusted certificate, so we install it separately on our computers.
By connecting to Canal IP-UPMC, for example, the user must validate the identity of the server accepting the certificate appears on the screen in a "popup window".
In reality, the user is unable to validate a certificate knowing, because a simple visual check of the license is impossible.
I have a HP Mini 110-1000, in connecting to the router by its HP Wirless Assistant, it has a message saying, "Windows was unable to find a certificate to log you on to the network . On the other hand, the wireless network connection keep showing 'validating identity '.
