Setting up your wireless network adapter 17Securing your Wi-Fi® NetworkIf your router has security (WEP or WPA) set, you will see this box when you try to connect. When this box opens, type the encryption key you set on your router, then click Connect.The next few pages are advanced options of setting the security through the adapter instead of the router.Note: When you select a network using encryption, you will first see the simple security screen. Click the Advanced button to see other security options (below).Wireless Equivalent Privacy (WEP) is a less secure, but more widely adopted wireless security protocol. Depending on the security level (64- or 128-bit), the user will be asked to input a 10- or 26-character hex key. A hex key is a combination of letters, a–f, and numbers, 0–9.Wi-Fi Protected Access (WPA) is the new standard in the wireless security. However, not all wireless cards and adapters support this technology. Please check your wireless adapter’s user guide to check if it supports WPA. Instead of a hex key, WPA uses only passphrases, which are much easier to remember.The following section, intended for the home, home office, and small office user, presents a few different ways to maximize the security of your wireless network.
18 Setting up your wireless network adapterCurrently, there are four encryption methods available:WEPWEP is a common protocol that adds security to all Wi-Fi-compliant wireless products. WEP gives wireless networks the equivalent level of privacy protection as a comparable wired network.WEP Encryption Keys—After selecting either the 64-bit or 128-bit WEP encryption mode, it is critical that you generate an encryption key. If the encryption key is not consistent throughout the entire wireless network, your wireless networking devices will be unable to communicate with one another. You can enter your key by typing in the hex key manually, or you can type a passphrase into the “Passphrase” field and click “Generate” to create a key. A hex (hexadecimal) key is a combination of numbers and letters from A–F and 0–9. For 64-bit WEP, you need to enter 10 hex characters. For 128-bit WEP, you need to enter 26 hex characters.For instance:AF 0F 4B C3 D4 = 64-bit WEP keyC3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7 = 128-bit WEP keyThe WEP passphrase is NOT the same as a WEP key. Your network adapter uses this passphrase to generate your WEP keys, but different hardware manufacturers might have different methods on generating the keys. If you have multiple vendors’ equipment in your network, the easiest thing to do is to use the hex WEP key from your wireless router (or access point) and enter it manually into the hex WEP key table in your network adapter’s configuration screen.64-Bit Wired Equivalent Privacy128-Bit Wired Equivalent PrivacyWi-Fi Protected Access-TKIPWi-Fi Protected Access 2Acronym 64-bit WEP 128-bit WEP WPA-TKIP/AES (or just WPA)WPA2-AES (or just WPA2)Security Good Better Best BestFeaturesStatic keys Static keys Dynamic key encryption and mutual authenticationDynamic key encryption and mutual authenticationEncryption keys based on RC4 algorithm (typically 40-bit keys)More secure than 64-bit WEP using a key length of 104 bits plus 24 additional bits of system generated dataTKIP (Temporal Key Integrity Protocol) added so that keys are rotated and encryption is strengthened AES (Advanced Encryption Standard) does not cause any throughput loss
Setting up your wireless network adapter 19WPAWPA is a new Wi-Fi standard that improves upon the security features of WEP. To use WPA security, the drivers and software of your wireless equipment must be upgraded to support it. These updates will be found on your wireless vendor’s Web site. There are three types of WPA security: WPA-PSK (no server), WPA (with radius server), and WPA2.WPA-PSK (no server) uses what is known as a pre-shared key as the network key. A network key is a password that is between eight and 63 characters long. It can be a combination of letters, numbers, or characters. Each client uses the same network key to access the network. Typically, this is the mode that will be used in a home environment.WPA (with radius server) is a system where a radius server distributes the network key to the clients automatically. This is typically found in a business environment.WPA2 requires Advanced Encryption Standard (AES) for encryption of data, which offers much greater security than WPA. WPA uses both Temporal Key Integrity Protocol (TKIP) and AES for encryption. Most Wi-Fi products ship with security turned off. So once you have your network working, you need to activate WEP or WPA and make sure all your wireless devices are sharing the same network key.IMPORTANT: You must now set all wireless network cards/adapters to match these settings.Configuring your Wireless N USB adapter to use securityYou should already have your wireless router set to use WPA or WEP. To make a wireless connection you need to set your Wireless N USB network adapter to use the same security settings.Changing the Wireless Security SettingsThe Wireless N USB network adapter supports the latest WPA security feature as well as the legacy WEP security standard. By default, wireless security is disabled.Your Dynex wireless adapter is equipped with the latest security standard called Wi-Fi Protected Access 2 (WPA2™) and the legacy security standard called Wired Equivalent Privacy (WEP). It also supports the Wi-Fi Protected Setup (WPS) specification, which simplifies the setup of a wireless network. WPS uses familiar methodologies, such as typing in a Personal Identification Number (PIN) or pushing a button, to enable you to automatically configure network names and strong WPA/WPA2 data encryption and authentication. Using Wi-Fi protected setup:• Encryption key if not using WPS• Personal Identification Number (PIN) method: Your wireless adapter generates a PIN to be entered into your router.• Push Button Configuration (PBC) method: Your wireless adapter can also connect by using the software pushbutton.• Manual configuration method: This section lists the default security settings to be set if you are not using WPS.
20 Setting up your wireless network adapterWPS uses WPA2 for encryption. It does not provide additional security, but standardized the method for securing your wireless network. On your client utility, WPS-enabled networks are indicated by a key icon. You can use either the PBC method or the PIN method to let a device access your wireless network.To use the PBC method:1Push and hold the WPS button (located on the back of your router) for three seconds. Initiate the WPS procedure on the client utility within two minutes.2Open the WNU and select the network name, then click Connect. Your client automatically exchanges security information and is added to your wireless network. You can also initiate the PBS method from the client side.To use the PIN method:1Open the WNU and select the WPS-enabled network, then click Connect.2Choose the PIN method option, then complete the WPS procedure on your router. Your client is automatically enrolled in your wireless network within two minutes.To enable security, you will first need to determine which standard is used by the router. (See your wireless router’s guide for directions on how to access the security settings.)To access the security settings on your card:1Open the WNU.2Click the My Connections tab, then click the connection you want to change.3Click Edit, then click Advanced to change settings.To access the security settings on your network adapter, click the My Connections tab and point to the connection for which you want to change security settings. Click Edit to change settings.Setting up WEPTo set up 64-Bit WEP encryption:1Select OPEN from the Network Authentication menu on the Wireless Network Properties tab on the Edit information for a network page.2Select WEP from the Data Encryption menu.
Setting up your wireless network adapter 213After selecting your WEP encryption mode, enter your key by typing in the hex key manually, or type in a passphrase in the Passphrase field, then click Generate to create a key.A hex (hexadecimal) key is a combination of numbers and letters from A–F and 0–9. For 64-bit WEP, you need to enter 10 hex characters.For instance:AF 0F 4B C3 D4 = 64-bit WEP key4Click Save to finish. Encryption in the wireless router is now set. Each of your computers on your wireless network will now need to be configured with the same security settings.Caution: If you are using a wireless client to turn on the security settings in your wireless router, you will temporarily lose your wireless connection until you activate security on your wireless client. Please record the key prior to applying changes in the wireless router. If you don’t remember the hex key, your client will be locked out of the wireless router.Setting up 128-bit WEP encryption:1Select OPEN from the Network Authentication menu on the Wireless Network Properties tab on the Edit information for a network page.2Select WEP from the Data Encryption menu.

For 128-bit WEP, you need to enter 26 hex characters.For instance:C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7 = 128-bit WEP key4Click Save to finish. Encryption in the wireless router (or access point) is now set. Each of your computers on your wireless network will now need to be configured with the same security settings.Caution: If you are using a wireless client to turn on the security settings in your wireless router, you will temporarily lose your wireless connection until you activate security on your wireless client. Please record the key prior to applying changes in the wireless router. If you don’t remember the hex key, your client will be locked out of the wireless router.To set up WPA-PSK (no server):Note: Choose this setting if your network does not use a radius server. WPA-PSK or WPA2-PSK (no server) is typically used in home and small office networking.1Select WPA-PSK or WPA2-PSK (no server) from the Network Authentication menu on the Wireless Network Properties tab on the Edit information for a network page.2Select TKIP or AES from the list.
Setting up your wireless network adapter 233Enter your network key. This can be from eight to 63 characters and can be letters, numbers, or symbols. This same key must be used on all of the clients (network cards) that you want to include in your network.4Click Save to finish. You must now set all clients (network cards) to match these settings.Wireless networking utility optionsThe Options tab on the Wireless Networking Utility (WNU) lets you customize your WNU settings.
24 TroubleshootingWNU HelpThe WNU Help tab lets you access online and telephone support, as well as advanced diagnostic tools.Advanced diagnostic toolsThe Advanced Diagnostic Tools section is the central control panel for all the settings of the hardware and software components of the wireless network. It provides an array of tests and connectivity services to ensure optimal network performance.TroubleshootingPlacement of your wireless networking hardware for optimal performanceYour wireless connection will be stronger the closer your computer is to your wireless router (or access point). Typical indoor operating range for your wireless devices is between 100 and 200 feet. In the same way, your wireless connection and performance will degrade somewhat as the distance between your wireless router (or access point) and connected devices increases. This may or may not be noticeable to you. As you move farther from your wireless router (or access point), connection speed may decrease.Factors that can weaken signals simply by getting in the way of your network’s radio waves are metal appliances, obstructions, and walls.
Troubleshooting 25If you have concerns about your network’s performance that might be related to range or obstruction factors, try moving the computer to a position between five and 10 feet from the wireless router (or access point) in order to see if distance is the problem. If difficulties persist, refer to the user guide for your wireless router.Note: While some of the items listed below can affect network performance, they will not prohibit your wireless network from functioning. If you are concerned that your network is not operating at its maximum effectiveness, this checklist may help.You cannot connect to the Internet wirelesslyIf you are unable to connect to the Internet from a wireless computer, check the following items:• Look at the lights on your wireless router. If you’re using a Dynex Wireless Router, the lights should be as follows:• The power light should be on.• The connected light should be on, and not blinking.• The WAN light should be either on or blinking.• Open your Wireless Networking Utility (WNU) software by clicking on the icon in the system tray at the bottom right corner of the screen. The tray icon should look like this (the icon may be red or green):• The window that opens should have a list of Available Networks. Available networks are wireless networks to which you can connect.If you are using a Dynex 802.11n router, Dynex is the default name.If you are using a Dynex 802.11g (54g) router, Dynex54g is the default name.If you are using a Dynex 802.11b router, the default name should be WLAN.If you are NOT using a Dynex router, please consult your router manufacturer’s user guide for the default name.The name of your wireless network appears in Available Networks list.If the correct network name is listed in the Available Networks list, follow these steps to connect wirelessly:1Click on the correct network name in the Available Networks list.2If the network has security (encryption) enabled, enter the network key. For more information regarding security, see “Securing your Wi-Fi® Network” on page 17.3Within a few seconds, the tray icon in the lower right corner of your screen should turn green, indicating a successful connection to the network.
26 TroubleshootingThe name of your wireless network DOES NOT appear in the list of Available Networks.If the correct network name is not listed under “Available Networks” in the WNU, try the following troubleshooting steps:1Temporarily move the computer, if possible, to 5 to 10 feet away from the wireless router. Close the WNU and reopen it. If the correct network name now appears under Available Networks, you may have a range or interference problem. See the suggestions listed in “Placement of your wireless networking hardware for optimal performance” on page 24.2Using a computer that is connected to the wireless router through a network cable (as opposed to wirelessly), make sure that Broadcast SSID is enabled. This setting is found on the router’s wireless Channel and SSID configuration page. For detailed instructions on accessing this page and changing settings, refer to the user guide for your wireless router.The installation CD does not start WNUIf the installation CD does not start the WNU automatically, it could be that the computer is running other applications that are interfering with the CD drive.To start the installation manually:1If the WNU screen does not appear within 15-20 seconds, open up your CD drive by double-clicking on the My Computer icon. 2Double-click on the CD drive that the installation CD has been placed in to start the installation. 3Double-click the Files folder, then double-click the Setup.exe icon.The power LED does not come ON. The network adapter is not workingIf the LED indicators are not ON, the problem may be that the network adapter is not connected or is not installed correctly.Make sure that the network adapter is plugged firmly into the USB port of your computer. Check to see that the drivers for the network adapter have been installed. Right-click on the My Computer icon on your desktop. Choose Properties and navigate to the Device Manager and see if your network adapter is listed without any errors. If an error is indicated, contact Technical Support.The link LED is blinking slowly. You cannot connect to a wireless network or the InternetIf your network adapter appears to be functioning correctly, but you cannot connect to a network or you have a red wireless icon at the bottom of your screen, the problem may be that there is a mismatch between the network name (SSID) settings in your wireless network properties.
Troubleshooting 27Check the SSID settings to see if they match. The SSID is case-sensitive and the spelling on each computer must be exactly the same in order for the network adapter to connect to the wireless router (or access point).Note: To check the SSID settings or look for an available network, double-click the Signal Indicator icon to bring up the Wireless Networks screen. Click Add if you do not see the network you are trying to connect to and type in the SSID.For more information about setting up an SSID, please refer to your router manufacturer’s user guide. Link LED is solid, but I cannot connect to the InternetIf you have a signal but cannot get online or obtain an IP address, the problem may be that there is a mismatch between the encryption key settings in your computer and wireless router.Check the WEP key settings to see if they match. The key is case-sensitive and the spelling on each computer and wireless router must be exactly the same in order for the network adapter to connect to the router (or access point). For more information about encryption, please see “Securing your Wi-Fi® Network” on page 17. Data transfer is sometimes slow or signal strength is poorWireless technology is radio-based, which means connectivity and the throughput performance between devices decreases when the distance between devices increases. Other factors that cause signal degradation are obstructions such as walls and metal appliances. As a result, the typical indoor range of your wireless devices will be between 100 to 200 feet. Note also that connection speed may decrease as you move farther from the wireless router (or access point).In order to determine if wireless issues are related to range, we suggest temporarily moving the computer, if possible, to 5 to 10 feet away from the wireless router. See “Placement of your wireless networking hardware for optimal performance” on page 24.Changing the wireless channel - Depending on local wireless traffic and interference, switching the wireless channel of your network can improve performance and reliability. The default channel the router is shipped with is channel 11. You may choose from several other channels depending on your region; see your router's (or access point's) user manual for instructions on how to choose other channels.
28 TroubleshootingLimiting the wireless transmit rate - Limiting the wireless transmit rate can help improve the maximum wireless range, and connection stability. Most wireless cards have the ability to limit the transmission rate. To change this property, click Start, Control Panel, Network Connections, then double-click your card's connection. In the Properties dialog, select the Configure button on the General tab (Windows 98 users will have to select the Wireless Card in the list box and then click Properties), then choose the Advanced tab and select the rate property. Wireless client cards are usually set to automatically adjust the wireless transmit rate for you, but doing so can cause periodic disconnects when the wireless signal is too weak; as a rule, slower transmission rates are more stable. Experiment with different connection rates until you find the best one for your environment; note that all available transmission rates should be acceptable for browsing the Internet. For more assistance, see your wireless card's literature.Why are there two wireless utilities in my system tray? Which one should I use?There are several features and advantages to using the WNU over the Windows XP Wireless Zero Configuration utility.
