Shared Key Setup – Select 64 Bit, 128 Bit, or 152 Bit key length.
Note that the same size of encryption key must be supported on
all wireless clients. (11b/g: 64/128 Bits; 11a: 64/128/152 Bits;
Default: 128 Bit)
Key Type – Select the preferred method of entering WEP
encryption keys on the access point and enter up to four keys:
• Hexadecimal: Enter keys as 10 hexadecimal digits (0 to 9 and
A to F) for 64 bit keys, 26 hexadecimal digits for 128 bit keys,
or 32 hexadecimal digits for 152 bit keys.

bit keys, 13 alphanumeric characters for 128 bit keys, or 16
alphanumeric characters for 152 bit keys.
