 After that do the following steps. These steps are actually provided by cisco

Learning Objectives

• Configure a PC to join a wireless network.
• Test the wireless connection.

Introduction

In this activity, you will configure the Linksys WRT300N wireless router to accept CompanyLaptop as a wireless client and route its IP packets.

Task 0: Changing WRT300N Display Name

Step 1. Change the WRT300N name

1. Click Wireless Router1 and navigate to the Config tab.
2. Change the Display Name to WRS1.
3. Close WRS1 window.
4. Notice that the topology now shows WRS1.

Task 1: Preparing the Network

Step 1. Preparing the Network

Note: This activity will ignore the existence of the WRT300N GUI tab to be closer to a real world situation. A management PC (PC0) is going to be prepared to access the Linksys wireless router via a wired connection. A web browser running on PC0 is going to be used to perform the entire configuration.

1. Select Connections from the bottom-left side of Packet Tracer.
2. Click Copper Straight-Through (solid black line).
3. Once the cursor changes to connection mode, click on PC0 and choose FastEthernet.

4. Click WRS1 and choose Ethernet 1.

Notice that WRT300N has 2 network segments: internal and internet. Ports Ethernet 1-4 and Wireless are considered part of the internal segment while the internet port is part of the Internet.WRS1 will act as a layer 2 switch to the devices connected to its internal segment and as a layer 3 router between the two segments. PC0 is now connected to the internal segment (Ethernet 1). OncePacket Tracer displays green dots on both sides of the connection between PC0 and WRS1, continue to Task 2.

Note: If no green dots are shown, make sure to enable Show Link Lights under Options > Preferences.

Task 2: Preparing PC0

In order to reach WRS1 management page, PC0 must be able to successfully communicate on the network. Linksys routers’ factory configuration includes a DHCP server. Such server is enabled by default on the internal LAN section of the router. To make sure PC0 acquires an IP address from the WRS1, configure PC0 to acquire IP information over DHCP.

Step 1. Setting up PC0 to use DHCP

1. Click PC0.
2. Select the Desktop tab.
3. Select IP Configuration.
4. Select DHCP.
5. What is the IP address of the computer?

6. What is the subnet mask of the computer?

7. What is the default gateway of the computer?

          Note: Values can vary within the network range due normal DHCP operation.

Task 3: Connect to the Wireless Router

Step 1. Logging into the Wireless Router

1. Close the IP Configuration window.
2. Still from the Desktop tab in PC0, Choose Web Browser.
3. Type in the IP address of the wireless router 192.168.0.1.
4. When asked for username and password, use admin for both. This is the default (factory settings) username/password for all the Linksys products.
5. Once WRS1 web based configuration page loads, continue to Step 2.

Step 2. Analyzing WRS1 Main Configuration Page

The main page deals with the router’s network setup. Scroll down this page and notice the DHCP server already enabled (from factory) and the range of IP addresses currently being server by the router over DHCP.

1. The IP address range served by the WRS1 over DHCP is 192.168.0.100/24. Is PC0 IP address within this range? Is this expected?

Step 3. Configuring WSR1 Internet Port

Since WRS1 will be routing wireless clients’ packets to remote networks, it is necessary to configure the Internet port. Linksys calls this interface the Internet Interface because it usually connects to an external network. In this activity this interface will be connected to the network segment containing Server0.

1. Change the Internet IP address method from Automatic Configuration – DHCP to Static IP.
2. Type the IP address to be assigned to the Internet interface as follows:

Internet IP Address:     192.168.20.1

Subnet Mask:               255.255.255.0

Default Gateway:         192.168.20.10

Leave the rest unchanged.

3. Scroll down the page and click Save Settings.
4. Click Continue and move on to Step 4.

Step 4. Configuring WSR1 SSID

1. From a web browser in PC0, log back into WRS1 (refer back to Task 3, Step 1 for more information).
2. Navigate to Wireless > Basic Wireless Settings.
3. Change Network Name (SSID) from Default to aCompany. Notice that SSIDs are case-sensitive.
4. Keep the other settings on this page in their defaults.
5. Scroll down the page and click Save Settings.
6. Laptop0 should now be associated to WRS1.

Task 4: Advanced Configuration

Step 1. Change WRS1 Access Password

1. From a web browser in PC0, log back into WRS1 (refer back to Task 3, Step 1 for more information).
2. Navigate to Administration > Management and change the current WRS1 current password to cisco.
3. Scroll down the window and click Save Settings.
4. The login window appears. Login again but this time using the new password cisco.

5. A page showing the message Settings are successful is displayed. Click Continue. 

Step 2. Changing DHCP address range in WRS1

Since the IP address assigned to the internal LAN interface of WRS1 must be within the range of IP addresses used by DHCP, the IP address of that interface must be changed.

1. From a web browser in PC0, log back into WRS1 using 192.168.0.1 as the website address, enter admin as the username and cisco as the password.
2. Navigate to Setup > Basic Setup.
3. Scroll down the page to Network Setup.
4. The IP address assigned to WRS1 internal LAN is 192.168.0.1/24. Change it to 192.168.50.1/24.
5. Scroll down the page and click Save Settings.
6. Note that the DHCP range of address has been automatically updated to reflect the interface IP address change.
7. Close the PC0 web browser.
8. Still from PC0 Desktop tab, Click on the Command Prompt.
9. Type ipconfig /renew to force PC0 re-acquire its IP information via DHCP.
10. PC0 IP address now belongs to the 192.168.50.0/24 IP range.

Check your score, you should have 100%.
