First: Obtain a Linksys "WUSB300N for V11A" adapter kit: it contains the USB wireless network adapter (with USB extension cable and Windows XP installation CD.) Before plugging in the adapter, verify that you are connected to the Internet via the usual copper network. You may need Internet access to install the driver. Plug in the adapter into one of the front USB ports. Windows 7 will automatically try to install the driver. If the driver was not installed, click on the pop-up message in the lower right of the screen. You should see the following information: Click on Change setting to use Windows Update: When the driver is installed successfully, you can proceed. You can verify by going to Control Panel then System (or right-click Computer then Properties), then Device Manager. Page 1 of 8
Part A - Windows WiFi in Infrastructure Mode Unplug your computer from the LAN by disconnecting the Cat 5 cable from either the back of the computer or the desktop jack. (If you go to Network Connections, the status of the Intel adapter will read "Network cable unplugged.") Connect to the Linksys Wireless Access Point (WAP), whose Service Set Identifier (SSID) is "L17-wireless". The security is set to WPA2-Personal, and the Shared Secret is "HelloWorld" (one word, all lower case.) This connection uses "Infrastructure" mode where a WAP or a wireless router is used to connect devices to the LAN. Verify that you have an IP address by running ipconfig /all from Command Prompt. Keep the window open. Verify that you have an Internet connection by opening any web site from a web browser. Keep the browser open. Show both windows to your professor [Mark #1] Part B - WiFi in Ad-Hoc Mode For this part, you can work in pairs. PC #1 Plug the Cat 5 cable that you disconnected in Part A, back into the LAN. Open Control Panel (Large icons View is best), Windows Firewall, and verify that Windows firewall is OFF. Open Control Panel, Network and Internet, then Network and Sharing Center. Click on Set up a new connection or network. The other useful choices, Manage wireless networks and Connect to a network are also shown below, for future reference. Page 2 of 8
This connection will set the adapter to Ad-Hoc mode. This allows two wireless adapters to communicate directly with each other instead of going through a WAP or wireless router. Enter a network name. Use the default Wired Equivalent Privacy (WEP) security. Enter a 10-digit security key, or equivalent (Windows will give you choices.) Page 3 of 8
PC #2 The Cat 5 cable should be unplugged. Verify that Windows firewall is OFF. Connect to PC #1's Ad-Hoc network using the wireless card. Give it a few seconds to settle. You should be able to ping PC #1. Keep the Command window open. Write down both PC s WiFi IP addresses (or you can type them in to Notepad, WordPad, etc.) PC #1 PC #2 Show the addresses and ping window to your professor [Mark #2] Page 4 of 8
Part C - Windows Network Bridging For this part, you can work in pairs. In Network Connections, create a Network Bridge between the Intel (copper) network adapter, shown as Local Area Connection and the Linksys (wireless) adapter, shown as Wireless Network Connection. PC #1 (the bridge) In the Network Connections window, click on both adapters by selecting one, holding down the control key and selecting the other. While still holding down Ctrl, right click and select Bridge Connections. PC #2 (the isolated network) From a Command Prompt, run ipconfig /release, then ipconfig /renew. Keep the command window open. Try to connect to the Internet. Keep the web browser window open. Write down PC #2 s WiFi IP Address Show the IP address and both windows to your professor [Mark #3] Page 5 of 8
Part D Windows Internet Connection Sharing For this part, you can work in pairs. Enable Internet Connection Sharing on the Intel (copper; Local Area Connection) adapter. Procedure D0. Remove the Bridge. First, delete the network bridge from PC #1. You may also have to select both network adapters again and remove the bridging, then delete the bridge. Procedure D1. Set a Static IP Address. On PC #1, run ipconfig /all and write down the following settings for the Ethernet adapter Local Area Connection only: IPv4 Address Subnet Mask Default Gateway DNS Server #1 DNS Server #2 (Ignore any additional DNS Servers.) Page 6 of 8
Procedure D1. (continued) Obtain your new Host ID from your instructor and write it down here: Your static IP address will begin with 192.168.3. and end with this number. On the copper NIC, right click to select Properties, select Internet Protocol Version 4, click on Properties. This pops up the TCPIPv4 Properties dialog box. Click on Use the following IP address and enter your new static IP address, the same Subnet mask as before, and the same Default gateway as before. Click on Use the following DNS server addresses and enter your two DNS server IP addresses. Click on OK, then OK again. Run run ipconfig /all to verify that your static IP address was set. Do the following tests to verify that all settings are correct: 1) Ping your static IP address. 2) Ping the default gateway. 3) Ping 192.197.62.35 (the Technology web server by IP address.) 4) Ping an your favourite web site by name (e.g., ca.yahoo.com.) Procedure D2. Enable Internet Connection Sharing. On the copper NIC, right click to select Properties, and switch to the Sharing tab. Under Internet connection sharing, check off Allow other network users to connect through this computer s Internet connection. On PC #2, run the ipconfig /release and ipconfig /renew again and try to connect to the Internet again. NOTE: You may need to reconnect to PC #1 s Ad-Hoc wireless network again. Page 7 of 8
Write down all the following information: PC #1 Copper IP Address (your static IP) WiFi IP Address PC #2 WiFi IP Address Default Gateway Show this information to your professor [Mark #4] To finish up: Disable the Internet Connection Sharing on PC #1. Change the copper NIC to TCPIPv4 settings to Obtain automatically again. Demonstrate that you have done this to your professor and get checked off on Blackboard. Page 8 of 8
