Packet Tracer – Configuring an Integrated Router

Objectives

Part 1: Connect to an Integrated Router

Part 2: Enable Wireless Connectivity

Part 3: Configure and Verify Wireless Client Access

Background

In this activity, you will configure an integrated router, allowing remote access to wireless clients as well as connectivity with WPA security.

Part 1: Connect to an Integrated Router

Step 1: Establish and verify connectivity to the integrated router.

a. Connect the appropriate cable from Host-A to the Ethernet 1 port on IR.
[alert-success]Use Copper Straight-Through to connect from port FastEthernet0 on Host-A to port Ethernet 1 on IR Router [/alert-success] b. Wait for the link light to turn green. Open the command prompt for Host-A. Use the ipconfig command to verify host-received IP addressing information.
[alert-success]Using command: ipconfig /renew
[/alert-success] c. Enter the command ping 192.168.0.1 to verify Host-A can access the default gateway.

Step 2: Access the IR graphical user interface (GUI) using a web browser.

a. Open the web browser on Host-A to access the GUI on IR for configuration. Enter the default gateway address of Host-A in the URL field.

b. Enter admin as the default username and password to access IR.

Part 2: Enable Wireless Connectivity

Step 1: Configure IR for Internet connectivity.

There is no Internet connectivity in this scenario, but you will still configure the settings for the Internet-facing interface. For Internet Connection Type, choose Static IP from the drop down list. Then enter the following static IP information:
– Internet IP Address – 198.133.219.1
– Subnet Mask – 255.255.255.0
– Default Gateway – 198.133.219.254
– DNS 1 – 198.133.219.10

Step 2: Configure the inside network parameters.

Scroll down to the Network Setup section and configure the following information:
– IP Address – 172.31.1.1
– Subnet Mask – 255.255.255.224
– Starting IP Address – Enter 5 for the last octet.
– Maximum number of Users – 25
Note: The IP address range of the DHCP pool will only reflect the changes after you click Save Settings.

Step 3: Save the settings and reconnect to IR.

a. Scroll to the bottom of the page and click Save Settings. If you move from one tab to another without saving, your configurations will be lost.

b. You lost your connection when you click Save Settings because you changed the IP address of the router.

c. Return to the command prompt of Host-A. Enter the command ipconfig /renew to renew the IP address.
[alert-success] [/alert-success] d. Use the Host-A web browser to reconnect to IR. You will need to use the new default gateway address. Verify the Internet Connection settings in the Status tab. The settings should match the values you configured in Part 2, Step 1. If not, repeat Part 2, Step 1 and Step 2.

Step 4: Configure wireless connectivity for wireless devices.

a. Click the Wireless tab and investigate the options in the dropdown list for Network Mode.
When would you choose to the Disable option?
[alert-success] When you do not have wireless devices. [/alert-success] When would you choose the Mixed option?
[alert-success] When you have wireless devices that consist of B, G or N [/alert-success] b. Set the network mode for Wireless-N Only.
c. Change the SSID to MyHomeNetwork.
d. When a wireless client surveys the area searching for wireless networks, it detects any SSID broadcasts. SSID broadcasts are enabled by default.
If the SSID of an access point is not being broadcast, how will devices connect to it?
[alert-success] The client must be configured with the name and correct spelling in order to make a connection. [/alert-success] e. For best performance in a network using Wireless-N, set the radio band to Wide-40MHz.

f. Click Save Settings and then click Continue.
