  2. 2. 1. Introduction This document describes the setup of Cisco Aironet 802.11a/b/g Wireless Adapter for Windows 2000 and Windows XP. • Cisco Aironet 350 Series Supports 802.11b - 2.4GHz at 11Mbps, configured with Aironet Client Utility (ACU). The card uses LEAP authentication, which is a secured form of wireless transmission. You can check the model of the wireless card by looking at the back of the wireless card. If your card is Cisco Aironet AIR-CB21AG-W-K9 Series, please refer to the guide for Cisco Aironet AIR-CB21AG-W-K9 Wireless LAN Adapter Setup Guide Note: 1. Before you proceed with the wireless setup mentioned below, please ensure that you are able to JOIN the NUS Domain. If you have not joined the NUS Domain and if you need help in joining the NUS domain, please refer to the NUSNET JOIN Domain guide available at the 2. Installing Drivers and ACU The setup program will install and configure the following: • Cisco Aironet 350 Wireless LAN Adapter driver • Aironet Client Utility (ACU) • ACU profile for NUS wireless network Step 1 Download the file from: Cisco Aironet 350 Series Wireless LAN Adapter Setup Guide Page 2 of 8
  3. 3. Step 2 Double click nusacu350.exe to launch the setup program. Click Next to start. Step 3 If you have inserted your Cisco wireless PC card, eject the card and click Continue. Cisco Aironet 350 Series Wireless LAN Adapter Setup Guide Page 3 of 8
  4. 4. Step 4 When you see the screen below, insert your Cisco wireless PC card, then click OK. Step 5 Setup will detect the inserted card and continue with the installation. Cisco Aironet 350 Series Wireless LAN Adapter Setup Guide Page 4 of 8
  5. 5. Step 6 You will be required to restart the computer at the end of the installation. Step 7 Logging in to the NUS Wireless Network ( Windows 2000, Windows XP Professional ) After you have joined domain, login to your computer using your NUSNET account as shown below Please note: * Windows XP Home Users If you are unable to join your computer to NUS domain, you need to create a user account in your computer with the same User Id and password as your NUSNET account. After creating the account, login to your computer using this account. To create a computer account, please click on “Start” -> “Control Panel” -> “User Accounts”.

  6. 6. 3. FAQ (Frequently Asked Question) Q1: What is an Access Point, wireless card, etc? Ans: These terms are explained below: Wireless Access Point Called AP in short or referred to as wireless Base Station. Wireless PC Card This is also called wireless PCMCIA card, wireless LAN adapter or simply wireless card. A notebook computer installed with a wireless card is able to access the Local Area Network (LAN) by communicating with the AP. The AP is a wireless LAN transceiver. When the notebook is within radio range (approximately 60 metres) of an AP, it can roam throughout the premise while maintaining uninterrupted access to the network. Service Set Identifier (SSID) An identifier attached to packets sent over the wireless LAN that functions as a "password" for joining a particular wireless network. All wireless cards and Access Points within the same wireless network must use the same SSID, or their packets will be ignored. Lightweight Extensible Authentication Protocol (LEAP) A Cisco wireless authentication protocol that ensure mutual authentication between a wireless client and a back end Access Control Server (RADIUS) server. Communication between the Access Point and the Access Control Server is via a secure channel. In addition, it provides a dynamic per-user, per-session encryption key generation mechanism.

  7. 7. Q2: What is the coverage of the wireless Access Point (AP)? Ans: The extent of the wireless coverage is approximately 60 metres from the Access Point. Q3: What are some of the factors that will affect AP's coverage? Ans: The Access Points are radio devices and they are susceptible to RF (radio frequency) obstructions and common sources of interference that can reduce throughput and range: Physical Environment Clear or open areas provide better radio range than closed or filled areas. Also, the less cluttered the work environment, the greater the range. Microwave ovens and 2-GHz cordless phones can cause signal interference because they operate in the same frequency range as the Access Point. Obstructions A physical obstruction such as metal shelving or a steel pillar can hinder performance of wireless devices. Avoid locating the devices in a location where there is a metal barrier between the sending and receiving antennas. Building Materials Radio penetration is greatly influenced by the building material used in construction. For example, drywall construction allows greater range than concrete blocks. Large steel structures such as shelving units, bookcases, filing cabinets, metal and steel construction are a barrier to radio signals. Q4: What are the setup requirements? Ans: The setup depends on the following: • Whether your are NUS Staff, Student or Visitor • The operating system • The type of wireless card used For wireless card not loaned from NUS, please refer to the product manual to determine if the card support ALL three radio channels (frequencies) — 1 (2412MHz), 6 (2437MHz) and 11 (2462MHz). The Access Points in NUS are configured with channel 1, 6 and 11 in a distributed fashion. Check with the shop that sells the card or the product's website to see if firmware upgrade is available to activate channels 1, 6 and 11. Alternatively, you can borrow a Cisco wireless card from the NUS loan counters if your card does not support all three channels. Q5: How do I reinstall or upgrade the wireless PC card driver and ACU? Ans: From Control Panel > Add/Remove Programs, uninstall the existing ACU. After that, restart your computer and run the setup again. Q6: What if my connection and login fails? Ans: Follow Q5 above to reinstall the drivers and software. Cisco Aironet 350 Series Wireless LAN Adapter Setup Guide Page 7 of 8
  8. 8. Q7: How to troubleshoot using the wireless card's indicator LEDs? Ans: The wireless card shows messages and error conditions through its two LEDs: • Link Integrity/Power LED (Green) This LED lights when the client adapter is receiving power and blinks slowly when the adapter is linked with the network. • Link Activity LED (Amber) This LED blinks quickly when the client adapter is receiving or transmitting data and blinks in a repeating pattern to indicate an error condition. Green LED Amber LED Condition Off Off Client adapter is not receiving power or an error has occurred. Blinking quickly Blinking quickly Power is on, self-test is OK, and client adapter is scanning for a network. Blinking slowly Blinking quickly Client adapter is associated to an Acess Point. Continuously on or Blinking Client adapter is transmitting or receiving data while blinking slowly associated to an Access Point. Off Blinking quickly Client adapter is in power save mode. On Blinking quickly Client adapter is in ad hoc mode. Off On Driver installed incorrectly. Off Blinking in a pattern Indicates an error condition. Q8: I am having problems with my wireless card, where can I get help? Ans: For further support, please email NUS IT Care at Cisco Aironet 350 Series Wireless LAN Adapter Setup Guide Page 8 of 8
