My 7 inch netbook authenticates to a wifi network with short network key but cannot authenticate to one with a very long key. I am using Win CE 6. The encryption method is AES, the authentication method is WPA-PSK. The short password key is 9 digits consisting only of numbers and letters. The long key consists of 35 digits, with spaces, capital letters, numbers and an exclamation mark. Can you help? Thanks.
