1. WEP According to the IEEE802 11 standard WEP can be used for authentication and data encryption 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 often 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 4121 provides 4 entities of WEP key settings that can be selected to use with Key index The selected key setting 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 type HEX and ASCII Each ASCII character has 8 bits so a 40 bit or 64 bit WEP key contains 5 characters 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 128 bit key has 26 characters WLAN Security Settings Security mode Authentication type Key type HE y Key length key index WEP key 1 WEP key 2 A WEP key 3 SCS J WEP key 4 ar Authentication type Data encryption is enabled but no authentication Open Data encryption and authentication are bo

Chapter 5 for details Keep in mind that WPA WPA2 CANNOT be supported in WDS To establish a static bridge link based on the WDS the APs at both end of the WDS link must be configured manually with each other s MAC addresses To establish a dynamic bridge link between an AP and a Client both devices must be configured with the same channel and security settings see WLAN Security Settings for details Moreover the same SSID is also needed for clients that roam the APs in Bridge mode The AP Client automatically scans for any AP that is using the matched SSID and establishes a bridge link with the scanned AP When the AWK 4121 is configured for Client mode it can be used as an Ethernet to wireless or LAN to WLAN network adapter For example a notebook computer equipped with an Ethernet adaptor but no wireless card can be connected to this device with an Ethernet cable to provide wireless connectivity to another AP NOTE Although it is more convenient to use dynamic bridging there is a limitation the AP Client can only transmit IP based packets between its wireless interface WLAN and Ethernet interface LAN other types of traffic such as IPX and AppleTalk are not forwarded Operation Mode The AWK 4121 supports four main operation modes Client AP Master and Slave each of which plays a distinct role on the wireless network Operation Mode Wireless enable Enable Disable Operation mode Wireless En
