Hello. I have used 2 USB sticks that worked with Yosemite. But they worked via a third party Wireless Network Utility, in this software I cannot enter a username and password, only a password. On my Eduroam (school) network I need to fill in a username and a password, but in this utility I can only enter a password. So I need a USB WiFi stick that works natively, using the OS X built-in WiFi system, using the tray in the top bar. I know this is possible, but I couldn't make it work. Any tips? -WoA.
