User Manual Part 2

34SSID & ChannelHere is where you may modify the SSID andChannel of your Wireless-G Broadband Router.• SSID (Service Set ID, or Network Name):Enter the name you wish to give your Wireless-GBroadband Router (ex. “JOHN” or “IOGEAR”).Every Wireless Clients (PC card, USB and PCIadaptors) in your network must be configured toaccept with the same SSID.• ChannelIt can be left as Default, unless you plan on usingmultiple access points. When multiple WirelessNetworks presenting, please ensure they are notusing the same channel, preferably at least 5channels apart to each other.• Accept Broadcast SSIDBy broadcasting SSID, all wireless devices atsurrounding area can see your wireless router andeasy to associate with it. However, it is a goodsecurity practice not to broadcast SSID, justconfigure SSID info to those client devices you wantthem to access you network.Configuration Utility
It allows you to configure the setting of networkauthentication and data encryption.• Network Authentication:You can specify the authentication type.- “Both” allows wireless client devices accessyour router no matter with shared key or not.- “Share Key” only allows devices with sameWEP (Wired Equivalent Privacy) key toaccess your wireless router.- “802.1X” and “WPA” require you to type inRadius server IP and server key. Pleasecheck with your Network Administrator forrelated information.- “WPA-PSK” needs a pre-shared key to be seton your wireless router and all wireless clientdevices.35Authentication & EncryptionConfiguration Utility
• Encryption:- WEP Configuration36Configuration UtilityClick the drop-down menu to select WEP to enablethe WEP function and select 64 bits or 128 bits. The128 bits gives a higher level of security. Theselection must be the same between all connectednetwork devices. For 64-bit WEP key, it should befive ASCII characters (a-z and 0-9, for example:gear56) or ten hexadecimal digits in length (athrough f, and 0 through 9, for example:2af30bc9d5); for 128 bit WEP key, the length will be13 characters for ASCII or 26 digits for Hexadecimal.WEP keys 1-4 enable you to create an encryptionscheme for wireless LAN transmissions.
37Configuration Utility WPA and WPA-PSK configurationWi-Fi Protected Access (WPA) is a sub-set of theforthcoming IEEE 802.11i security standard. WPAaddresses those known weakness of WEP andprovides stronger security to wireless network.IOGEAR Wireless-G Broadband Router supportsthree authentication modes:• 802.11x (need RADIUS server to authenticatethe clients, using WEP keying)• WPA (same 802.1x, but with TKIP keyingsupport); WPA-PSK (Pre-Shared Key, noRADIUS server needed)- WPA-PSK
38- WPAConfiguration UtilityThere are two ways to configure WPA Pre-Shared Key:1. PassPhrase Mode: Input a phrase into the field.The Wireless-G Broadband Router will automati-cally generate a Pre-Shared Key based on thephrase you enter. The phrase can be within 8 to 63characters (we recommend at least 12 charactersto achieve a sufficient level of security).2. Hex mode: Input 64 hexadecimal digits. Pleasewrite down the key you enter. You will need to entersame key to your wireless client side.WPA Group Rekey IntervalThis router could change the group key periodically.Enter the period you want into the WPA Group RekeyInterval field.Encryption TypeThe current version only supports TKIP encryption.AES encryption will be available soon.
39Configuration UtilityRADIUS Server IPPlease enter the IP address of RADIUS serverRADIUS Server PortThis field specifies the port on which RADIUS serveris listening.RADIUS Server KeyThis field carries the shared secret for RADIUSauthentication. Some information need to beencrypted in a RADIUS packet, this key is used toencrypt and decrypt this information (such aspassword).Reconfirm RADIUS Server KeyMake sure RADIUS Server Key is correct.WPA Group Rekey Interval It is the same as WPA-PSK configurationEncryption TypeIt is the same WPA-PSK configurationNote:To complete the WPA operation, you also need to enable theWPA client at the wireless client site (the computer runningwireless client’s devices, such as the GWP511 Cardbus cardGWP512 Cardbus Card or GWU513 USB adaptor).Microsoft provides a free WPA upgrade for Windows XPService Pack 1 (SP1) and later or Windows Server 2003. Forany OS other than Win XP, there is client software availablefrom third-party suppliers such as Funk Software’s Odyssey(www.funk.com). IOGEAR’s GWP512 Wireless-G Network PCCard has it built-in.The WPA client for Windows XP can be found in the MicrosoftKnowledge Base Article 815485 (http://support.microsoft.com/default.aspx?scid=kb;en-us;815485) or downloaded directlyfrom Microsoft http://www.microsoft.com/downloads/details.aspx?FamilyID=009d8425-ce2b-47a4-abec-274845dc9e91&displaylang=en
40Configuration UtilityAfter installed, the Windows WPA Client will update thewireless network configuration dialog boxes to support newWPA options.1. Click Connect To>Wireless Network Connectionto bring up the dialogue window of WirelessNetwork Connection Status. Click theProperties box to bring up next dialogue window.2. In the Wireless Network Connection Propertieswindow, under Wireless Networks tab, pleasecheck the box of “Use Windows to configure mywireless network settings” to turn on theWireless Zero Configuration service. Select thewireless access point you want to associate to,then click Configure box at the right side to bringup next dialogue window.
3. Set up your WPA configuration by selecting theNetwork Authentication mode and Dataencryption, and input same Network key as youinput at the Wireless-G Broadband Gateway.Then, you are served by a more secured wirelessnetwork41Configuration Utility
Here you can configure Wireless radio settings.Please note that these settings are for advanced usersor network administrators. If you are unfamiliar withhow to configure these parameters, we recommendthat you keep them at their default value.• Mode: The Wireless-G Broadband Router can be setat three wireless modes: Auto, 802.11g only and802.11b only. If both 802.11g and 802.11b clientspresenting at your network, please select “Auto”mode (This is default mode). “802.11g only” modeonly supports 802.11g clients, and gives betterperformance to whole network. However, all 802.11bclients will not be able to use your network at thismode setting. In some situation, 802.11b clients withold drivers cannot work with Auto mode; “802.11bonly” mode can accommodate this problem, butdecrease the performance of 802.11g devices.42Configuration UtilityRadio Setting
• Beacon Period: Beacons are packets sent by therouter to synchronize a wireless network. The valueof beacon interval is depending on the environmentwhere the router is operating. Specify a Beaconinterval value between 1 and 1000(units: ms). Thedefault value is set to 100 milliseconds, i.e., tenbeacons per second.• RTS Threshold: The RTS threshold is the packet sizeat which packet transmission is governed by theRTS/CTS transaction. Each station can have adifferent RTS threshold. If you encounter inconsistentdata flow, only minor modifications are recom-mended. The default value for RTS Threshold is setto 2347.• Fragment Threshold: This value should remain at itsdefault setting of 2346. If you experience a highpacket error rate, you may modify slightly your“Fragmentation” value within the value range of 800to 2346. Setting the Fragmentation value too low mayresult in poor performance.• DTIM Period: Enter a value between 1 and 255 forthe Delivery Traffic Indication Message (DTIM). ADTIM is a countdown informing clients of the nextwindow for listening to broadcast and multicastmessages. When the router has buffered broadcastor multicast messages for associated clients, itsends the next DTIM with a DTIM Interval value. Itsclients hear the beacons and awaken to receivethe broadcast and multicast messages. The defaultvalue for DTIM interval is set to 1.43Configuration Utility
