edit: it's an wpa-peap connection with mschapv2. the certificate is an root ca certificate, which i don't have to choose under "certificate", because the n810 should find it by itself. but there are a few threads, that this is maybe a bug in os2008... in the howto, they write that you have to install "wpa-supplicant" to configure the conenction. is there a way to install and use that program on maemo? or maybe mer is a solution for my problem? maybe i'll install mer on mini-sd and try it out...
