And i noticed that when choosing a network to connect to and if secure, i have to enter a security key like the one is figure 8(in the link above). but for my school connection, i have to enter a username and password so i was wondering if this makes it impossible to connect to my school network using my phone because it only has a enter security key option. can someone enlighten me on this please, thanks a lot.
