WEP Security
WEP - Key Type and Key Index
MCS7 (150Mbps) or MCS15 (300Mbps).
Note: In case you have selected WEP, WPA-TKIP or WPA2-TKIP security method, the maximum data rate is MCS12. This is a hardware
limitation due to the Atheros HAL. Should you need a higher data rate try using WPA-AES or WPA2-AES.
Automatic: When the Automatic checkbox is selected, the rate algorithm will select the best data rate, depending on link quality
conditions. It is recommended to use the automatic option, especially if you are having trouble getting connected or losing data at a
higher rate. Refer to the section Advanced for the detailed information about rate algorithms.

Wireless Security
This section enables you to set parameters that control how the subscriber station associates to a wireless device and encrypts/decrypts
data.
Choose the security method according to the Access Point security policy.
Subscriber station should be authorized by Access Point in order to get access to
the network and all the user data transferred between a subscriber station and
Access Point will be encrypted if the wireless security methods are used.
Security: Security: AirOS supports none, WEP, WPA, and WPA2 security
options. Select the security mode of your wireless network:
WEP – enable WEP encryption. WEP (Wired Equivalent Privacy) is based on
the IEEE 802.11 standard and uses the RC4 encryption algorithm. Enabling
WEP allows you to increase security by encrypting data being transferred
over your wireless network. WEP is the oldest security algorithm, and there
are few applications that can decrypt the WEP key in less than 10 minutes.
WPA™/WPA2™ security methods should be used when possible.
WPA – enable WPA™ security mode. Wi-Fi Protected Access - WPA™ (IEEE 802.11i/D3.0) and
WPA2™ (IEEE 802.11i) with pre-shared key management protocol offers improved security
methods as they are new protocols that were created under the 802.11i standard to address
weaknesses in the WEP approach.
WPA™ and WPA2™ support the following ciphers for data encryption:
TKIP - Temporal Key Integrity Protocol that uses RC4 encryption algorithm.
AES (also known as CCMP) - Counter Mode with Cipher Block Chaining Message Authentication
Code Protocol, which uses the Advanced Encryption Standard (AES) algorithm.
The device will use the strongest cipher (AES) in Station and Access Point wireless mode by default. If AES is not supported on the other
side of the link the TKIP encryption will be used - like in situation when the device acts as Access Point with WPA security enabled and at
least one wireless station (without AES support) is connected to it.
WPA – enable WPA™ security mode.
WPA-TKIP – enable WPA™ security mode with TKIP support only.
WPA-AES – enable WPA™ security mode with AES support only.
WPA2 – enable WPA2™ security mode.
WPA2-TKIP – enable WPA2™ security mode with TKIP support only.
WPA2-AES – enable WPA2™ security mode with AES support only.
WEP
Authentication Type: field relates only to the WEP security option. One of the
following authentication modes should be selected if WEP security method is used:
Open Authentication – station is authenticated automatically by AP (selected by
default).
Shared Authentication – station is authenticated after the challenge, generated by
AP.
WEP Key Length: 64-bit (selected by default) or 128-bit WEP Key length should be
selected if WEP security method is used. The 128-bit option will provide a bit higher level of
wireless security.
Key Type: HEX (selected by default) or ASCII option specifies the character format for the
WEP key if WEP security method is used.
WEP Key: WEP encryption key for the wireless traffic encryption and decryption should be
specified if WEP security method is used:
For 64-bit – specify WEP key as 10 HEX (0-9, A-F or a-f) characters (e.g. 00112233AA) or 5 ASCII characters.
For 128-bit – specify WEP key as 26 HEX (0-9, A-F or a-f) characters (e.g. 00112233445566778899AABBCC) or 13 ASCII
