Help Wireless 'Connect' button grayed out

[RandomSF]

At a friend's house today, I tried to connect to his wireless network and after typing in the password, the Connect button stayed grayed out. If I typed a few additional characters, the button was no longer grayed out, but since this was obviously the wrong password it could not connect.

Is there a minimum password for WiFi, or is there some other setting I can change so I can connect?

I came across this because because I'm having the same problem with my GS3, the only thing that solved it was installing a WiFi manager app from the market and connecting through that.
