Wireless Router Configuration Example - WRT54G

WRT54G Basic Setup - Click to EnlargeOnce you have logged in successfully to the Wireless router you will be taken to the Basic Setup configuration page where the routers LAN IP, Internet Connection Type and DHCP options are set. The WRT54G can be used to connect to the internet via adsl or cable in a number of different ways however we shall configure our example as seen in the diagram on the previous page, where its WAN port shall be connected into an ADSL modem. You should change your internet connection type to suit your needs of course but in this instance we shall use a static IP address. A static IP address is an address that is directly configured into a computer or device rather than relying on it being assigned via DHCP. Because we are changing both the WAN and LAN IP addresses they will changed at the same time to avoid conflicts.

WRT54G IP Address Setup

  • Select Static IP as the connection type
  • Set the Internet IP address as 192.168.1.20
  • Set the Subnet Mask to be 255.255.255.0
  • Set the Gateway address to be the address of the ADSL modem 192.168.1.1
  • Static DNS 1 has been set to the address of the ADSL modem as it has a built in nameserver 192.168.1.1
  • Static DNS 2 and 3 are our ISP's nameserver addresses
  • Router Name can be changed to whatever you wish but Host Name, Domain Name and MTU (in particular) should not be changed unless instructed to do so by your ISP.

WRT54G IP Address Setup

  • Set the Local IP Address to 192.168.2.1
  • Make sure the subnet mask is correct - 255.255.255.0
  • Enable the DHCP server so that client computers will be automatically assigned an IP address (or disable to ensure they dont)
  • The starting IP address for the DHCP server is the first IP address that will automatically be handed out. The default should be fine.
  • Ensure the maximum number of DHCP users setting is higher than the number of intended users.
  • Leave client lease time and WINS configuration as they are.

WRT54G save settingsOnce you have completed the IP configuration of the router click on the Save Settings button on the bottom of the page so that the router will store the configuration on its flash drive and make the changes permanent. When you change the LAN IP address on most devices the device will have to reboot to use the new address settings and it will do this automatically. With the WRT54G your web browser will display a page suggesting you renew your IP address or change it so that your computer is on the same network as the router so that you may continue to configure it.

WRT54G save settings and continueA note that with settings that dont require a restart of the router you will getting a different page that states that the Settings were Successfull. Clicking on the continue button on this page will return you to the settings you were last editing.

WRT54G Basic WirelessOnce you have logged back into your router it is time to configure your Wireless Settings so that client computers can connect securely. In the web admin interface click on Wireless in the menu at the top and you will be taken to Basic Wireless Settings. Select the mode you would like to operate your wireless network on, 802.11b (B only), 802.11g (G only) or both (Mixed). Using both is the best way to ensure all your wireless cards can connect unless you are certain that they can only do one or the other. Most G standard cards are backwards compatible with B. Type in the SSID that you would like to transmit so that your network can be identified during a scan. To refresh our memory an SSID or ESSID is like a beacon that your network transmits so clients can see it. Many devices do not like their SSID to be in capital letters, it seems to cause problems with some client computers when they try to connect. Select the channel that you would like your wireless network to run on. Most countries have the choice of 10 or 13 different channels depending on their regulation domain. The next choice is to hide the SSID. This is not recommended until all of your clients are configured as it prevents the SSID from being seen during a scan. Once you have finished in the Basic Wireless Settings section click Save Settings at the bottom and then click Continue once the Settings are Successful page is displayed.
