How to Change the Password in a Linksys Router WRT54GS


The Linksys WRT54G, made by Cisco, is a broadband wireless router that allows both hardwired and wireless users to share network resources, namely Internet connectivity, printers and server access. A Linksys router may be protected by two separate passwords, which don't have to be the same. To configure the router or change the password, you need to know the unit's user name and password. To change the wireless network settings or password, you also have to know the wireless network password.

Things You'll Need

  • Ethernet RJ-45 cable
  • Connect your computer to the Linksys router using an Ethernet RJ-45 cable. Plug one end into your computer's network jack and the other end into one of the numbered jacks on the back of the router. Note the jack number you've plugged into; confirm that the corresponding light on the front of the unit indicates your computer is successfully connected.

  • Launch a Web browser (Internet Explorer, Firefox, Safari or Google Chrome) and enter "" in the URL bar. You will be prompted to enter a user name and password; enter "admin" for both. If the user name and/or password has been changed by a previous user or the URL doesn't bring up the Linksys login page, reset the router as described in Step 5.

  • Click on the "Administration" tab to change the user name and/or password. Enter a new user name and password in the appropriate fields and click the "Save" button. Take note of what you've entered; you'll need to know it the next time you want to change any settings on the Linksys router.

  • Change the wireless network password by clicking on the "Wireless" tab and then the "Wireless Security" tab on the row below. Select "WPA-Pre-Shared Key" to create your own password for the wireless network; choose "WEP" from the pull-down menu to have a random password generated for you. Record your password and keep it in a safe place.

  • Reset your Linksys to factory defaults if you cannot access the configuration page. Use a pen to depress the "Reset" button on the back of the unit for 45 seconds. This will revert the configuration IP number to and both the user name and password to "admin." The wireless network name will revert to "linksys" and will be unsecured. Reestablish network security by using the process described in Step 4.

Tips & Warnings

  • Make screen grabs of all the setting pages on the Linksys router to use as a guide if you have to reconfigure the router.
  • Remember that all passwords are case-sensitive.
  • All wireless clients will have to reconnect using the new wireless network password.
  • When you reset a Linksys router that connects via DSL, you will be required to reenter your DSL user name and password.
