Opens the MAC filter (page 114) form, allowing the specification of the MAC addresses of devices to allow in the network. Hide Network SSID (page 114) Hides the Network SSID (Network Name) from other 802.11 users. Clients can connect to the "hidden" network by typing the Network SSID

Encryption Type The preferred encryption type is WPA or WPA2 (WiFi Protected Access) using AES. You should only select TKIP for use with an older client radio that does not support AES or WEP (wired equivalency protocol). For compatibility with clients that do not support WPA, you can select TKIP+WEP128 as the encryption type. Then older clients can connect to the RLX2 using the WEP setting, but all other links will use the more secure WPA encryption.

Important: 

If the RLX2 model supports 802.11n rates and they are enabled, then all ‘TKIP only’ and TKIP/WEP options are disabled. If a client radio only supports TKIP, then use the AES & TKIP option. If the client radio only supports WEP, then switch the 802.11 Mode control to ‘802.11 a/g and then select the appropriate WEB setting in this control. Important: If TKIP+WEP128 is selected, 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 a WEP key other than key 1 and set this same key for all clients that are using WEP. See WEP key.

When the WEP Security mode is selected, 

you can then select WEP128 or WEP64 as the encryption type but none of these settings 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, for several reasons. 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
