Hi jsamanta!

First of all check if the power light is blinking or solid. if it's blinking reset your router.

When your computer is directly connected to the router try checking the IP address by clicking start>run> type cmd then ok. then type ipconfig then hit enter. IP address should be something like not 169.254.xx.xx. if it's the latter reset your router. use a ball point pen or a paper clip. the reset button is a small hole at the back. If the IP address is like the first one i've mentioned. log-in to your router.

launch browser (internet explorer or firefox)
type or whatever your default gateway is. go to the status tab and check if you are getting a WAN or internet IP address. if not you will see a "release" and "renew" button. hit release then renew. if you're still not getting anything. do a power cycle. turn everything off. connect everything the way they are supposed to be connected. turn on modem first then router then computer.

If everything fails the last options is a firmware update on the router.

Hope this helps. =)

    Sorry if none of that worked. can you give me the exact model and version of the router?

    Can you also give me the status of the power light? is it solid or blinking?

    What is the IP address that you are getting when your computer is connected to the router?

  • mrbrown0603

    You can find the firmware and other information for your router HERE.

    Don't forget to select the version.

    Who's your ISP maybe it's just settings that we need to configure.

    • Before you start, be sure you are using a PC that is connected to the WRT54G via a wired (Ethernet) connection.

    • Open your web browser (e.g., Internet Explorer, Netscape, etc.)
      In the Address bar, type in the IP address of your router. The default IP address is

    • Leave the username blank and enter your password. The default password is "admin" all lower case.

    • Click on the Administration tab.

    • Click on Firmware Upgrade.

    • Browse for the firmware file that you have just extracted. The file name should end in .bin

    • Click the Upgrade button.The router will begin its upgrade routine. Do not power off or unplug the router until the process is completed. This process may take up to 5 minutes to complete.

    Can you try cloning the mac address of your computer to the router. You can do it on the router's configuration page.

My router just stopped working. The internet

There can be several causes for this:

1. Check for power to the router which can be lost because of a loose DC plug or bad power brick.

2. Check the DSL or cable modem if it is working properly and can get you on line if directly plugged into your PC.

3. If any of the above are ok, then your router has just died. Routers have a high rate of failure so I won't be surprised if this was the case with yours.

Lost internet connection

Change the calbe from the router to the dsl modem. Make sure you check labels on the rear of these devices to make sure the connections go where indicated. Is there and ethernet light on your modem. If that is on then the connection is made. Also check if the DSL modem works directly connected to the pc.
