Has she definitely entered sufficient characters for the Password? WPA/WPA2 requires a minimum of 8 characters and the "Connect" button isn't active until at least 8 characters have been entered.
The number of characters for WEP is more complicated:
32-bit WEP uses 5 ASCII or 10 Hexadecimal characters.
64-bit WEP uses 13 ASCII or 26 Hexadecimal characters.
Some WEP devices don't like an ASCII key and a Hex key must be used. Post back if you need further help.
