By | 9th November 2015

On this page, we will look at how to configure a Linksys wireless router, allowing for remote access from PCs as well as wireless connectivity with WEP security. We will use the topology diagram below as sample.

The router R1 and switch SW2 had been configured with the appropriate configurations with the LAN and VLAN

Before you begin, you might like to do a reset on the wireless router. In order to clear any previous configurations, do a hard reset. Look for the reset button on the back of the router. Using a pen or other thin instrument, hold down the reset button for 5 – 7 seconds. The router should now be restored to its factory default settings.

Establish physically connectivity.

 

  1.     Connect a straight through cable from the Laptop PC to one of the wireless router’s LAN ports, labelled Ethernet 1 – 4. By default, the wireless router will provide an IP address to the laptop using default DHCP configurations.





Open a web browser.

 

  1.      Navigate to the wireless router’s Web Utility. You can use the WEB GUI will be used to configure the settings on the wireless router. The GUI can be accessed by navigating to the router’s LAN/Wireless IP address with a web browser. The factory default address is 192.168.1.1.
  1.    Leave the username blank and set the password to: admin.
  1.    Configure Options in the Linksys Setup Tab.

 

By default the start-up page is the Setup screen. Here, you will need to set the Internet connection type to static IP. In the menus at the top notice you are in the Setup section and under the Basic Setup tab.

  1.     • In the Setup screen for the Linksys router, locate the Internet Connection Type option in the Internet Setup section of this page. Click the drop-down menu and select Static IP from the list.
  1.     Configure theVLAN99 IP address, subnet mask, and default gateway for the Linksys Wireless Router.
  • Set the Internet IP address to 172.17.99.25.
  • Set the Subnet Mask to 255.255.255.0.
  • Set the Default Gateway to 172.17.99.1.




Note: Typically in a home or small business network, this Internet IP address is assigned by the ISP through DHCP or PPPoE.

  1.     Configure the router R1 IP parameters.
  • Still on the Basic Setup page, scroll down to Network Setup. For the Router IP fields do the following:

* Set the IP address to 172.17.30.1 and the subnet mask to 255.255.255.0.

Under the DHCP Server Setting, ensure that the DHCP server is Enabled.

Click the Save Settings button at the bottom of the Setup screen.

 

At this stage, you will notice that the IP address range for the DHCP pool adjusts to a range of addresses to match the Router IP parameters. These addresses are used for any wireless clients that connect to the router’s internal switch. Clients receive an IP address and mask, and are given the router IP to use as a gateway.

  1.    Set the network name (SSID).
  • Click the Wireless tab.
  • Under Network Name (SSID), rename the network from Linksys to any name of your choice, example orbitcisco1.
  • Click Save Settings.
  1.    Set the security mode.
  • Click Wireless Security. It is located next to Basic Wireless Settings in the main Wireless tab.
  • Change Security Mode from Disabled to WEP.
  • Using the default Encryption of 40/64-Bit, set Key1 to 1234567890 or any combination of hex digit only,
  • Click Save Settings.
  1.  Set the router password.
  • Click the Administration tab.
  • Under Management in the Router Access section, change the router password to orbit123 or any password of your choosing. Re-enter the same password to confirm.

11.  Enable remote management.

  • In the Remote Access section, set Remote Management to Enabled.
  • Click Save Settings.
  • You may be prompted to log in again. Use the new password of cisco123 and still keep the username blank
  1. Enable remote management.
  • In the Remote Access section, set Remote Management to Enabled.
  • Click Save Settings.
  • You may be prompted to log in again. Use the new password and still keep the username blank.
  1. Add Wireless Connectivity to a laptop PC
  1. Disconnect the Ethernet connection from the laptop to Wireless Router.

ii: Use Windows XP to connect to the wireless router.

Below is on how to use Windows XP’s built in Wireless Network Connection Utility. Depending on the model of NIC you use, this might be disabled, and you will need to use the utility provided by the NIC manufacturer.

click Start > Control Panel > Network Connections.

  • Select the Wireless Network Connection.
  • Navigate to the File menu and select Status.
  • Click View Wireless Networks.
  • Locate the ‘orbitcisco1 or whatever names you gave to your network SSID in the list of available networks and connect to it.
  • When prompted for the WEP key enter it as above, 1234567890 or whatever key you used and clickConnect.
  1. Verify your Connection.
  • In theStatus window, select the Support tab. Verify that the Laptop has received an IP address from the Wireless router’s DHCP address pool or has been manually configured.
