Linksys WRT54G Installation and Configuration

Configuration

  1. Using the "Quick Installation Guide", follow the instructions in step 1 to set up your new wireless router. You may also need to restart your computer in order to see the router.

    Note: If you normally use a static IP address, you will have to reconfigure your internet connection to use DHCP. Go into the control panel and open your network connections. Edit the properties of your current network connection, and make sure that "Obtain an IP address automatically" is enabled.

  2. Connect to the router using your web browser by typing "http://192.168.1.1" into the URL address box.
  3. Leave the Username field blank, and enter the password "admin" to access your router when the login prompt appears.

    Note: You will notice immediately a list of menu options (Setup, Wireless, Security, etc.), and as you click on each of these submenus appear. This document will refer to a menu-submenu combination as Menu -> Submenu.

  4. Setup -> Basic Setup. In the "Internet Setup" section, choose "Static IP" from the drop down menu. Fill in the appropriate values that describe your network. (You don't need to change anything in the optional section just below that.)

  5. In the "Network Setup" section, you should at least set your timezone to Eastern Time, although you may make changes to the DHCP server as well if you anticipate more than 50 users connecting to your network at once.

  6. Wireless -> Basic Wireless Settings. Set the Wireless network mode to "Mixed" if you would like both B and G clients to be able to connect to your network. Otherwise you can just select "B-only". The "Wireless Network Name" will be provided by CNS. Make sure that you disable "Wireless SSID Broadcast" to give a little extra security.

  7. Wireless -> Wireless Security. CNS recommends that you use at least WEP based security to protect your network. Choose WEP from the drop down menu and then select "128 bits 26 hex digits" for the "WEP Encryption". Enter a passphrase into the "Passphrase" field and click "Generate" to generate the corresponding HEX keys. Distribute key 1 to your users as the WEP key for your network.

  8. Wireless -> Wireless MAC Filter. CNS also recommends that you use a MAC address list to filter access to your network. Click the "Edit MAC Filter List" and add all the MAC addresses that are going to be accessing your network. Any time a new user requires access, you will have to add them to this list.

    IMPORTANT NOTE: Make sure that you add the MAC address of the computer you are using to set up your router first, before enabling this filter. Otherwise you will be unable to access the router and will have to reset the router. If you do have to reset the router because you have locked yourself out, there is a small reset button on the back of the router that will reset the router.


    Once the appropriate MAC addresses have been added, "Enable" the filter, and choose the option "Permit only PCs listed to access the wireless network".
  9. Administration -> Management. You should make sure you change your password on this screen. "admin" is not a secure password! Also, you should disable "Remote Router access" so that your router cannot be configured from outside your network. UPnP is a protocol that opens ports in your firewall on the fly, and can post a security threat. We recommend that you disable this, but if you are running applications like MSN video chat, you may have to have this enabled.

  10. Administration -> Log. If you would like to keep a log of connections to your network, enable the logging here.

  11. That's it! You should be on the air!
