Comment 142 for bug 422174

Reading around the problem, I found that some wifi drivers don't seem to run the KeyRing Authorization routine properly if a hidden SSID is used. This leads to the authorization not getting saved.

This FIXED it for me: At the router, temporarily enable SSID broadcast. Make a connection and Save. Test WiFi with Disconnect and Connect. Go back to the router, re-disable broadcast and hide your router. Re-test, your connection should still work. In theory ...

( For me, a Realtek 8187)
