Task 3: Basic Wireless Settings

Step 1. Configure the SSID.

To start securing the wireless network, access the Wireless page and change the default

Network Name (SSID) from Default to WRS1.

Step 2. Save settings.

Scroll down the page and then click Save Settings. When the settings are accepted by theLinksys WRT300N, a Request Timeout message will appear in the web browser window.

 After this message is displayed, continue to Step 3.

Step 3. Reconnect to the wireless network.

Since the SSID has changed, WirelessPC1 is currently unable to access the network. Onthe Desktop return to PC Wireless and select the Connect tab. Connect to the WRS1

network.

Task 4: Enable Wireless Security

Step 1. From the Web Browser on WirelessPC1, reconnect to the routersetup page (http://192.168.1.1).

Step 2. Navigate to the Wireless page and then select the Wireless Securitytab.

Step 3. Under Security Mode, select WEP.

Step 4. Enter a WEP key.

 A network is only as secure as its weakest point, and a wireless router is a very convenientplace to start if someone wants to damage your network. By requiring a WEP key to connectto the router, you are adding a level of security.

Unfortunately, there are tools that can crack WEP key encryption. A more robust form ofwireless security is WPA and WPA-2, which are currently not supported by Packet Tracer.

 Add the WEP key 1234567890 in the Key1 field.

Step 5. Save your settings.

Scroll down the page and then click Save Settings. You will become disconnected from thenetwork again after saving your settings. When the settings are accepted by the LinksysWRT300N, aRequest Timeout message will appear in the web browser window. After thismessage is displayed, continue to Step 6.

Step 6. Configure WirelessPC1 to use WEP authentication.
