Introduction

In this lab, you will configure and test the wireless settings on a wireless router.

Recommended Equipment

  • A computer with Windows installed
  • A Wireless NIC installed
  • An Ethernet NIC installed
  • A wireless Router
  • Ethernet patch cable

Note: All wireless settings in this lab are for a 2.4 GHz wireless connection. Follow the same steps for setting up a 5 GHz wireless connection or when setting up both 2.4 GHz and 5 GHz connections.

Answers Note: You will need to provide a unique router address settings, DHCP server settings, SSID for each router in the classroom, and a router access password.

Step 1: Gathering Information

Ask the Answers for the following information:

Router IP Information (IP address and subnet mask): _____________________________________________

Router name:______________________________________________________________________________________

DHCP Server Information (start IP address and maximum number of hosts):_____________________

Static DNS 1 (optional):____________________________________________________________________________

SSID:_______________________________________________________________________________________________

Channel number:__________________________________________________________________________________

Router Username/Password:______________________________________________________________________

Wireless Security (passphase key):________________________________________________________________

Note: Only use configurations assigned by the Answers.

You will need to provide the student with the following information for the router:

Router_name#, name# (where # is a different number assigned to each router)

IP information: IP address, subnet mask to be used by the router’s internal interface.

DHCP Server Setting information: start IP address of the DHCP pool and maximum number of users.

SSID: name#, where # is a different number assigned to each router.

Channel: assign each group a different wireless channel number to avoid frequency conflict.

Wireless Security: the security passphase key for WPA2 Personal.

For example:

Router Address Information:

IP address:192.168.1.254/255.255.255.0

Router name: ITE1

DHCP Server Setting Information: Start IP address:192.168.1.25; maximum number of users: 10

Static DNS 1 (optional): 64.7.99.178

SSID: Cisco1

Channel number: 6

Router Username/Password: admin1/admin1#

Wireless Security: passphase key: ITEv6.0!

Step 2: Connecting to the Wireless Router

  1. Plug in the power of the wireless router. Boot the computer and log in as an administrator.
  2. Connect the computer to one of the Ethernet ports on the wireless router with an Ethernet patch cable.
    Note: If this is the first time connecting to the lab router, you must set the network location in Windows.
  3. Open the command prompt. Type ipconfig /renew to force the computer to request an IP address from the wireless router via DHCP.
    is the IP address of the default gateway for the computer?
    ____________________________________________________________________________________
    192.168.1.1 (Answers may vary)
    What device took the role of default gateway?
    ____________________________________________________________________________________
    ____________________________________________________________________________________
    Because the computer is connected to the wireless router with the DHCP server enabled, it learns IP address from the router. In this situation, the wireless router is the default gateway.

Step 3: Logging into the Wireless Router

  1. Open a web browser, type the IP address of your default gateway in the URL field, and then press Enter.
