WEP Key
An 802.11a device with WEP enabled uses a WEP Key to encrypt and decrypt
information. If the WEP Keys do not match on two radios, no data communication will
take place between these devices.
The Harmony 802.11a PCI Card can support up to four WEP Keys (all four Keys must
have the same Key Size). The Harmony 802.11a PCI Card can decrypt information that
was encrypted with any of its four WEP Keys. A Harmony 802.11a PCI Card will only
use the Default Key to encrypt outgoing information.
For 40-bit encryption, a WEP Key is 10 hexadecimal digits (0-9 and A-F); for 128-bit
encryption, a WEP Key is 26 hexadecimal digits (0-9 and A-F); and for 152-bit
encryption, a WEP Key is 32 hexadecimal digits (0-9 and A-F).
Note: When WEP is enabled, Proxim recommends that you configure all 802.11a
devices in the Extended Service Set with the same WEP Keys in the same
order (but the devices not need to use the same default Key).
