Wireless-N USB Network Adapter Appendix A: Troubleshooting This appendix consists of two parts: “Common Problems and Solutions” and “Frequently Asked Questions.” This appendix provides solutions to problems that may occur during the installation and operation of the Wireless-N USB Network Adapter. Read the description below to solve your problems. If you can't find an answer here, check the Linksys website at www.linksys.com. Common Problems and Solutions 1.
Wireless-N USB Network Adapter What is the IEEE 802.11g standard? It is one of the IEEE standards for wireless networks. The 802.11g standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11g standard. The 802.11g standard states a maximum data transfer rate of 54Mbps and an operating frequency of 2.4GHz. What 802.11b features are supported? The product supports the following 802.
Wireless-N USB Network Adapter simultaneously requires a dynamic RF networking technology that links access points and nodes. In such a system, the user’s end node undertakes a search for the best possible access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each access point and the distance of each access point to the wired backbone.
Wireless-N USB Network Adapter What is WPA? WPA is Wi-Fi Protected Access, a wireless security protocol that can be used in conjunction with a RADIUS server. What is WPA2? WPA2 is Wi-Fi Protected Access2, a wireless security protocol that can be used in conjunction with a RADIUS server, but has stronger encryption than WPA. What is RADIUS? RADIUS is Remote Authentication Dial-In User Service, which uses an authentication server to control network access.

Wireless-N USB Network Adapter 2. The screen that appears will show any available wireless network. Select the network you want. Click the Connect button. NOTE: Steps 2 and 3 are the instructions and screenshots for Windows XP with Service Pack 2 installed. If your network does not have wireless security enabled, go to step 3. If your network does have wireless security enabled, go to step 4. Figure B-4: Available Wireless Network 3.
Wireless-N USB Network Adapter 4. If your network uses wireless security WEP, enter the WEP Key used into the Network Key and Confirm network key fields. If your network uses wireless security WPA Personal, enter the Passphrase used into the Network Key and Confirm network key fields. Click the Connect button. Figure B-6: Network Connection - Wireless Security NOTE: Windows XP Wireless Zero Configuration does not support the use of a passphrase. Enter the exact WEP key used by your access point. 5.
Wireless-N USB Network Adapter Appendix C: Wireless Security Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of Linksys products provide several network security features, but they require specific action on your part for implementation. So, keep the following in mind whenever you are setting up or using your wireless network.
Wireless-N USB Network Adapter 1. Disable Broadcast 2. Make it unique 3. Change it often Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast the SSID. Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is “linksys”.) Hackers know these defaults and can check these against your network.
Wireless-N USB Network Adapter WPA Personal. If you do not have a RADIUS server, Select the type of algorithm, TKIP or AES, and enter a password in the Passphrase field of 8-63 characters. WPA2 Personal. If you do not have a RADIUS server, enter a password in the Passphrase field of 8-63 characters. WPA Enterprise. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router or other device.
