WPA/WPA2 Pre-shared key (PSK) mode is defined in IEEE 802.11i-2004. That specification *recommends* using 8 6o 63 ASCII-encoded characters and the HMAC-SHA-1 pseudorandom function PBKDF2 to derive encryption keys. See: http://standards.ieee.org/getieee802/download/802.11i-2004.pdf It appears you have equipment that does not abide by this recommendation. If you need to pad with spaces, you might try using quotes. However, a short PSK password is not recommended. "A key generated from a passphrase of less than about 20 characters is unlikely to deter attacks." [1] "...against current brute-strength attacks, 96 bits SHOULD be adequate."
