First-time Installation and Configuration

Before installing the AWK-1121/1127, make sure that all items in the Package Checklist are in the box. You will need access to a notebook computer or PC equipped with an Ethernet port. The AWK-1121/1127 has a default IP address that must be used when connecting to the devic e for the fir s t time.
• Step 1: Select the power source. The AWK-1121/1127 may be powered by a DC power input or PoE (Power over Ethernet, PoE model only).
• Step 2: Connect the AWK-1121/1127 to a notebook or PC. Since the AWK-1121/1127 supports MDI/MDI-X auto-sensing, either a straight-through or crossover cable may be used to connect to a computer. The LAN port LED indicator will lig ht up whe n a connection is established.
• Step 3: Set up the computer’s IP address. Choose an IP address on the same subnet as the AWK-1121/1127. Since the AWK-1121/1127’s default IP address is 192.168.127.253, and the subnet mask is 255.255.255.0, you should set the IP address of the computer to 192.168.127.xxx.
• Step 4: Use the web-based manager to configure the AWK-1121/1127

Communication Testing

After installing the AWK-1121/1127 a simple test may be run against an AP to make sure the AWK-1121/1127 has properly established a wireless connection and is functioning normally. In the example below, an AWK-3121 is used as the primary access point.
How to Test an AWK-1121/1127 for Network Connectivity
Connect an AP-configured AWK-3121 (or another access point) to Notebo ok A. Connect an AWK-1121/1127 to Notebook B. Config ure the AWK-1121/1127 and AWK-3121 for the same SSID, and set their IP addresses as below.
After setting up the testing environment, open a DOS window on notebook B. At the prompt, type:
ping <IP address of notebook A>
and then press Enter. A “Reply from IP address …” response means the communicatio n was succe ssful. A “Request timed out” response means the communication failed. In this case, be sur e to first reche ck the configuration to make sure the connectio ns are corre c t.

WLAN Security Settings
The AWK-1121/1127 provides four standardized wireless security modes: Open, WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), and WPA2. Several security modes are availab l e in the AWK-1121/1127 by selecting Security mode and WPA type:
• Open: No authentication, no data encryptio n.
• WEP: Static WEP (Wired Equivalent Privacy) keys must be configured manually.
• WPA/WPA2-Personal: Also known as WPA/WPA2-PSK. You will need to specify the Pre-Shared Key in the Passphrase field, which will be used by the TKIP or AES engine as a master key to generate keys that actually encrypt outgoing packets and decryp t inc oming packets.
• WPA/WPA2-Enterprise: Also called WPA/WPA2-EAP (Extensible Authentication Protocol). In addition to device-bas ed authe ntic ati o n, WPA /W PA 2-Enterprise enables user-based authentic ation via IEEE802.1X. The AWK-1121/1127 can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

Open
For security reasons, you should NOT set security mode to Open (or “Open System”), since authentication and data encryption are NOT performed in Open (or “Open System” ) mode.
WEP
According to the IEEE802.11 standard , WEP can be used for authenticat i o n and data encryption to maintain confidentiality. Shared (or Shared Key) authentication type is used if WEP authentication and data encryption are both needed. Normally, Open (or Open System) authentication type is used when WEP data encryption is run with authentication.
When WEP is enabled as a security mode, the length of a key (so-called WEP seed) can be specified as 64/128 bits, which is actually a 40/104-bit secret key with a 24-bit initialization vector. The AWK-1121/1127 provides 4 entities of WEP key settings that can be selected to use with Key index. The select ed key sett ing specifies the key to be used as a send-key for encrypting traffic from the AP side to the wireless client side. All 4 WEP keys are used as receive-keys to decrypt traffic from the wireless client side to the AP side.
The WEP key can be presented in two Key types, HEX and ASCII. Each ASCII character has 8 bits, so a 40-bit (or 64-bit) WEP key contains 5 charac ter s , and a 104-bit (or 128-bit) key has 13 characters. In hex, each character uses 4 bits, so a 40-bit key has 10 hex characters, and a 104-bit key has 26 hex characters.

WPA/WPA2-Personal
WPA (Wi-Fi Protected Access) and WPA2 represent significant improvements over the WEP encryption method. WPA is a security standard based on 802.11i draft 3, while WPA2 is based on the fully ratified version of 802.11i. The initial vector is transmitted, encrypted, and enhanced with its 48 bits, twice as long as WEP. The key is regularly changed so that true session is secur ed.
Even though AES encryption is only include d in the WPA2 s tandar d, it is widely available in the WPA security mode of some wireless APs and clients as well. The AWK-1121/1127 also supports AES algorithms in WPA and WPA2 for better compatibility.
Personal versions of WPA/WPA2, also known a s WPA/WPA -PSK (Pre-Shared Key), provide a simple way of encrypting a wireless connection for high confidentiality. A Passphrase is used as a basis for encryption methods (or cipher types) in a WLAN connection. The passphrases should be complicated and as long as possible. There must be at least 8of ASCII characters in the Passphrase, and it could go up to 63. For security reasons, this p assp hras e sho uld only be disclosed to users who need it, and it should be changed regularly.

EAP-TLS
TLS is the standards-based successor to Secure Sock et La ye r (SSL ). It can establish a trusted communication channel over a distrusted network. TLS provides mutual authentication through certificate exchange. EAP-TLS is also secure t o use. You are required to submit a digital certificate to the authentication server for validation, but the authentication server must also supply a certificate.
You can use Basic Wireless Settings WLAN Certificate Settings to import your W LAN certificate and enable EAP-TLS on the client end.
• Certificate issued to: Shows the certificate user
• Certificate issued by: Shows the certificate issuer
• Certificate expiration date: Indicates when the certificate has expired
EAP-TTLS
It is usually much easier to re-use existing authenticatio n s ystems, such as a Windows domain or Active Directory, LDAP directory, or Kerberos realm, rather than creating a parallel authentication system. As a result, TTLS (Tunneled TLS) and PEAP (Protected EAP) are used to support the use of so-called “legacy authentication methods.”
TTLS and PEAP work in a similar way. First, they establish a TLS tunnel (EAP-TLS for example), and validate whether the network is trustworthy with digital certificates on the authentication server. This step establishes a tunnel that protects the next step (or “inner” authentication), and consequently is sometimes referred to as “outer” authentication. The TLS tunnel is then used to encrypt an older authentication protocol that authenticates the user for the network.
As you can see, digital certificates are still need ed for outer authentication in a simplified form. Only a small number of certificates are required, which can be generated by a small certificate authority. Certificate reduction makes TTLS and PEAP much more popular than EAP-TLS.
The AWK-1121/1127 provides some non-cryptographic EAP methods, including PAP, CHAP, MS-CHAP, and MS-CHAP-V2. These EAP methods are not recommended for direct use on wireless networks. However, they may be useful as inner authentication method s with TTL S and PEAP.
Because the inner and outer authentications can use distinc t us e r name s in TTLS and PEAP, you can use an anonymous user name for the outer authentication, with the true user name only shown through the encrypted channel. Keep in mind that not all client software supports anonymous alteration. Confirm this with the network administrator before you enable identity hiding in TTLS and PEAP.

There are a few differences in the TTLS and PEAP inner authentication procedures. TTLS uses the encrypted channel to exchange attribute-value pairs (AVPs), while PEAP uses the encrypted channel to start a second EAP exchange inside of the tunnel. The AWK-1121/1127 provides MS-CHAP-V2 merely as an EAP method for inner authentication.
