None (Plain ‐ text)
If you select None as your security mode, no further options are configurable on the AP. This mode means that
any data transferred to and from the UAP is not encrypted.This security mode can be useful during initial
network configuration or for problem solving, but it is not recommended for regular use on the Internal
network because it is not secure.
Static WEP
Wired Equivalent Privacy ( WEP ) is a data encryption protocol for 802.11 wireless networks. All wireless stations
and APs on the network are configured with a static 64 ‐ bit (40 ‐ bit secret key + 24 ‐ bit initialization vector (IV))
or 128 ‐ bit (104 ‐ bit secret key + 24 ‐ bit IV) Shared Key for data encryption.
Static WEP is not the most secure mode available, but it offers more protection than setting the security mode
to None (Plain ‐ text) as it does prevent an outsider from easily sniffing out unencrypted wireless traffic.
WEP encrypts data moving across the wireless network based on a static key. (The encryption algorithm is a
stream cipher called RC4.)
Note: After you configure the VAP settings, you must click Apply to apply the changes and to save the
settings. Changing some settings might cause the AP to stop and restart system processes. If this
happens, wireless clients will temporarily lose connectivity. We recommend that you change AP
settings when WLAN traffic is low.

Field Description
Transfer Key Index Select a key index from the drop ‐ down menu. Key indexes 1 through 4 are available. The
default is 1.
The Transfer Key Index indicates which WEP key the AP will use to encrypt the data it
transmits.

• 64 bits
• 128 bits
