What is the difference between a passphrase and a security key?
A passphrase is a sequence of words that are used by some wireless security protocols to generate a security key. The methods of generating the security key from the passphrase can vary from device to device. WEP wireless security generates security keys from the passphrase. Since the methods of generating the security key from the passphrase are not standardized, the wireless adapter setup screens on your DIRECTV Receiver only accept the WEP security key. With WPA wireless security, the passphrase is the security key and can be entered.
