11.5.4.2 Lab – Connect and Test the Wireless Connection Instruction ITE7

Lab – Connect and Test the Wireless Connection

Introduction

In this lab, you and your partner will connect your computers to a wireless router and test the wireless connection.

Required Resources

  • Wireless router
  • 2 Windows computers
  • Internet access

Instructions

Step 1: Configure the wireless router as necessary.

If the wireless router has been restored to default factory settings, you and your partner should configure the wireless router with the settings provided by your instructor. If not, record the information provided by your instructor and go to the next step.

Router IP address / subnet:
DHCP Server Starting IP address / Maximum
number of users:
Router Administrative Username / Password:
Router Username / Password:
Your Assigned SSID:
Wireless Security Option and Passphrase:

Note: Only use configurations assigned by the instructor.

Step 2: Connect your Windows computer to the router wirelessly.

a. Disconnect the Ethernet cable from your computer.

b. Click the network icon in the system tray. You will see a list of wireless networks that are broadcasting their SSIDs within the range of your computer.

c. Select your assigned SSID. Select Connect automatically if you are planning to connect to it again.

d. Click Connect and provide the passphrase when prompted.

e. After you have successfully connected to the wireless network, determine and record your IP address and the default gateway.

f. Provide your IP address to your partner.

g. Open a command prompt, and ping 127.0.0.1 to test the loopback.

Question:

How many replies did you receive?

Why would you perform this test?

h. Ping the default gateway. It should be successful if you are connected to your wireless router.

i. Attempt to ping your partner’s computer. It should be successful. If it is not successful, the Windows Firewall may have prevented the ICMP traffic.

Step 3: Disable SSID broadcast on the wireless router.

You can disable the SSID broadcast on your wireless router. This could prevent unauthorized users from connecting to the wireless network, but it is not a security feature.

a. Log into the wireless router.

b. Navigate to the wireless settings and search for the page for disabling SSID broadcast for your wireless router. SSID broadcast is usually enabled by default. Refer to the manufacturer’s documentation as needed.

c. Change the SSID so you are required to connect to a new wireless network. Record the new SSID.

d. Verify that the settings have been saved.

Step 4: Connect to the hidden wireless network.

Now that the SSID is no longer broadcast, it will not be listed in the list of wireless networks. You will need to manually set up a new wireless connection.

a. Navigate to the Control Panel. In the Small icon view, select Network and Sharing Center.

b. Click Set up a new connection or network. Select Manually connect to a wireless network. Click Next.

c. Select the wireless adapter if you have more than one. Click Next to continue.

d. Provide the network name (SSID), the security type, the encryption type, and the security key.

e. If you would like to start this connection automatically, select the checkbox.

f. Select Connect even if the network is not broadcasting so your computer can connect to the hidden network.

g. Click Next to continue. Click Close.

h. After you are connected to the hidden wireless network, verify your IP address has not changed. If it was changed, provide this information to your partner. Then verify that you can ping your partner and the wireless router.

i. Restore the wireless router to the previous state or as directed by your instructor.

Step 5: Connect to a wireless network with Internet access

In this step, you will connect to a wireless network with Internet access. If you cannot do it wirelessly, you can connect via an Ethernet cable for this step.

a. Use the tracert command to Cisco Networking Academy website. At the prompt, enter tracert www.netacad.com.
