Encryption Type
We recommend that you use WPA or WPA2 (Wi-Fi Protected Access) using AES for the


Use TKIP with an older client radio that does not support AES.

Use WEP (Wired Equivalency Protocol) with an older client radio that does not
support AES or TKIP.

For compatibility with clients that do not support WPA, you can select TKIP+WEP128
for the E
NCRYPTION

Older clients can connect to the RLX2-IHx series radio using the WEP setting, but all
other links use the more secure WPA encryption.
Important: If the 802.11n data rates are supported and enabled in the RLX2-IHx series radio, then all TKIP
and TKIP/WEP options are disabled. If a client radio only supports TKIP, then use the AES
option. If the client radio only supports WEP, then in the 802.11 M
then select the appropriate WEP setting.
Important: If you select TKIP+WEP128, some clients using WPA might not be able to connect unless you
use a WEP key other than number 1, due to limitations in these clients. In such cases, you should set WEP
K number to a value other than 1 and set this same key for all clients that are using WEP. See WEP Key

When you select WEP for the S
are available but neither are recommended.
WEP is the original security protocol used by 802.11 networks but should only be used if
interoperability with a legacy device is essential. Tools are available that allow an
attacker to break the WEP keys simply by sniffing an active WEP network for a few
minutes. WPA offers vastly better protection against attacks. WPA distances the
encryption key from the actual data by performing several algorithms to create a Session
key before encrypting any data, and it performs dynamic key management by changing
keys frequently.
Note: If an RLX2-IHx series radio is set to use TKIP+WEP128, it can connect to other radios set to WPA
only or WPA+WEP, but it will not communicate with radios using only WEP. Likewise, an RLX2-IHx series
radio in Client mode with TKIP+WEP128 selected will not connect to an access point using only WEP.
