8GN-A15AG Wireless Access Point User GuideFollow these steps to install the Wireless Access Point.Hareware Installation1.Choose a proper place for Access Point. In general, the best location is at the centerof your wireless coverage area, within line of sight to all wireless devices. Keepingclear of metal obstructions and away from direct sunlight.2.Place the Access Point in the desired location. Normally, the higher you place theantenna, the better the performance will be. The antenna’s position enhances thereceiving sensitivity.3.Attach one end of an RJ-45 Ethernet cable to the Access Point and attach the otherend to a network hub, switch, router, or patch panel (possibly on a wall).4.Attach one end of the AC power adapter to the Access Point and the other end to apower outlet. (Note: Only use the power adapter supplied by Gigabyte in the productpackage. Using a different adapter may result in product damage.)For the average home, signal range should not be an issue. If you experience low or nosignal strength in areas of your home that you wish to access, consider positioning theAccess Point in a location directly between the computers with wireless adapters. Addi-tional Access Points can be connected to provide better coverage in rooms where thesignal does not appear as strong as desired.Wired Ethernet CableConnect to Access PointYou can connect a Crossover cable from your computer’s Network card to the AccessPoint without using a Network switch or hub.Wireless ConnectionIf you are using the wireless connection, you can connect to the Access Point using theGigabyte Access Point Manager without a wired Ethernet cable.

Once accepted, this key is usedfor a short time only. Then a new key is generated and agreed upon.Shared Key is both the sender and the recipient share a secret key.If the “Shared Key” and “Both” option is selected, it will not be able to perform theoption “disable” of the WEP Type.This page is the security configuration of the wireless connection. Protects your informa-tion with the highest level of industry-standard WEP encryption: 64/128-bit for 802.11bstandard, and up to 152-bit for 802.11g standards. When the “Disable” is selected there isno WEP encryption. When “64bits”, “128bits” or “152bits” selected there is encrypteddate transfer to prevent unauthorized user to access the wireless network.You may choose between “Open System”, “Shared Key”, “Both”, “802.1x -Dynamic WEP”, “WPA”, “WPA-PSK”. The Authentication Type default is set to “OpenSystem”.
GN-A15AG Wireless Access Point User Guide25If the 802.1x – Dynamic WEP option is selected, the Radius/WPA page will appearas shown below.RADIUS server IP,Please assign a IP address to the primary RADIUS server(authentication server).RADIUS Port, The setting range is 1~65536 and the default value is 1812.RADIUS sercet, This filed can key in up to 256 character.RADIUS Re-Key,Under this option two setting are possible: “enable” or “disable”.The default value is “enable”.Verify the desired setting and then click the “Apply” button to set the value into accesspoint.WPAif you have been using Wi-Fi for a while, you are probably familiar with the802.1X authentication protocol. This protocol allows users to authenticateinto a wireless network by means of a RADIUS Server. In standard Wi-Fi,802.1X authentication is optional. However, 802.1X authentication is arequirement for WPA. If your environment does not have a RADIUS serverin place, you can still use WPA in spite of the 802.1X requirement. As analternative to RADIUS, WPA supports the use of a preshared key.
26GN-A15AG Wireless Access Point User GuideAES (Advanced Encryption Standard), A standard, sponsored by theNational Institute of Standards and Technology, for protecting datathrough encryption. AES supports key sizes of 128 bits, 192 bits and256 bits and will serve as a replacement for the Data EncryptionStandard (DES), which has a key size of 56 bits. In addition to theincreased security that comes with larger key sizes, AES canencrypt data much faster than Triple-DES, a DES enhancement thatwhich essentially encrypts a message or document three times.One of the biggest drawbacks to traditional WEP security is thatchanging the encryption key is optional. Even ifyou do switchencryption keys from time to time, there isno option for globallyrekeying all access points and all wireless NICs.Instead, rekeying is a tedious manual process and is completelyimpractical for large organizations. After all, the instant you rekey anaccess point, none of the clients will be able to access it until theyare also rekeyed.But with WPA, the rekeying of global encryption keys is required. Inthe case of unicast traffic, the encryption key is changed after everyframe using Temporary Key Integrity Protocol (TKIP). This protocolallows key changes to occur on a frame by frame basis and to beautomatically synchronized between the access point and thewireless client. Global rekeying works by advertising the new keys towireless clients.The TKIP is really the heart and soul of WPA security. TKIP replacesWEP encryption. And although WEP is optional in standard Wi-Fi,TKIP is required in WPA. The TKIP encryption algorithm is strongerthan the one used by WEP but works by using the same hardware-based calculation mechanisms WEP uses.The TKIP protocol actually has several functions. First, it determineswhich encryption keys will be used and then verifies the client’ssecurity configuration. Second, it is responsible for changing theunicast encryption key for each frame. Finally, TKIP sets a uniquestarting key for each authenticated client that is using a presharedkey.WPA PSKWPA use of a preshared key.
