This problem is caused by the firmware not loading correctly. Follow the steps below to fix this:
Note: This process must be done on a computer plugged into the router directly.
Preparation
- You first need to establish a connection to the Internet and download firmware for your router.
To get online, bypass the router and plug directly into your Cable or DSL modem. - Download the latest firmware upgrade for your router from http://www.linksys.com/download.
Be sure to select the WRT54G and the correct version number that matches your router. Look on the bottom of the router to verify the model and version (no version number means version 1.0). - Click on Downloads for this Product. When the Downloads page loads, click on the Firmware button.
- Click Download to download the firmware.
- Before performing the upgrade, we recommend you assign your computer a static IP address like 192.168.1.2.
Reloading the firmware
- First, hold the reset button located on the back of the router for 30 seconds.
- Next, to test communication between the Router and the network card: Go to Start, and select Run. Type in command and press [Enter]. This will bring up the MS-DOS prompt window.
- Type ping 192.168.1.1 and press [Enter]. You should get the following results:
Pinging 192.168.1.1 with 32 bytes of data: Reply from 192.168.1.1: bytes=32 time<10ms TTL=128 Reply from 192.168.1.1: bytes=32 time<10ms TTL=128 Reply from 192.168.1.1: bytes=32 time<10ms TTL=128 Reply from 192.168.1.1: bytes=32 time<10ms TTL=128 - Once you get these replies, open the router web interface by typing http://192.168.1.1 in the web browser. Type in the Router’s user name and password (admin by default).
- Upload the firmware you downloaded before and click Upgrade to start the firmware upgrade process. The upgrade will take about 1 to 2 minutes.
- Once the upgrade is complete, the router’s Diag light (or Power light) should no longer be blinking.
Note: Be sure to go back to your network card settings (from the steps above) and change the speed of the link back to “Auto sense” or “Auto” (the original default setting) to restore full speed to the adapter.
