    Been happily using my Linksys WRT54G wireless router for a few months now and it suddenly decided to stop working on me yesterday.Im new to all networking so apologies if I am just being thick!

    My problem is that when I now turn on my router,the power lights ,network port lights continually flash. I have tried pressing the reset button for 10seconds,15 seconds and a full minute and that does nothing. I then read I may need to flash my firmware but to do this, the linksys manual says to connect to your router through http:/ (connected through an RJ45 network cable) but that doesnt work either. I have downloaded some new automatic firmware programme from linksys and that just says "router not connected".

    I have read about using tftp or something but I dont understand how to do it. I would be very grateful if anybody could help because if not it is going to be a trip to PC world to buy another one at 70quid!

    Kind Regards

    Recovering Linksys from a bad Firmware Flash.
    Q U E S T I O N
    My router's red Diag light (or Power light) is blinking. How do I fix this?
    A N S W E R
    This 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.
    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 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. 3.
    Download the firmware Auto Upgrade Utility .exe file from this page. 4.
    Before performing the upgrade, we recommend that you do the following: 5.
    Assign your computer a static IP address. For more information, please see Article KB10934010 for
    information on setting up a static IP address in Windows.
    If using a 10/100 network adapter, change its speed to 10Mb, half duplex. Please see the instructions
    below on how to do this.
    Windows 95/98/ME
    At the Windows desktop, click on Start then choose Settings and click on Control Panel. 1.
    Double click the Network icon. This will bring up the “Network Configuration†window. 2.
    Locate and highlight the icon with the green logo for your network adapter and click Properties. 3.
    This will display the network adapter's Properties 4.
    Select the Advanced tab and click Connection Type (this may also appear as Media Type, Connection
    Speed, Mode, Link Speed, etc). The current Default value should be set to "Auto sense" or "Auto".
    Change the value of this option to 10Base−t, half duplex mode (usually the lowest possible option).
    The wording of this value may also vary, depending upon the make and model of the Network
    Adapter. Other possibilities include 10T half, 10Mb half duplex, 10Mbps half, etc.
    Once this has been changed, click OK to return to the Network configuration screen 7.
    Click OK again and Windows will ask to restart your computer. Click “Yes†to restart. 8.

    Reloading the firmware
    First, hold the reset button located on the back of the router for 30 seconds. 1.
    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 and press (Enter) 3.
    You should get the following results: 4.
    Pinging with 32 bytes of data: ·
    Reply from bytes=32 time<10ms TTL=128 ·
    Reply from bytes=32 time<10ms TTL=128 ·
    Reply from bytes=32 time<10ms TTL=128 ·
    Reply from bytes=32 time<10ms TTL=128 ·
    Once you get these replies, close out of the command prompt by typing in exit and pressing (Enter). 1.
    Double click on the firmware file that you downloaded in Step 2. The “Firmware Upgrade Utilityâ€
    will open.
    Click Next and type in the routers “IP Address†( is the default address of the router) and
    type in the “Router’s Password†(admin is the default password for the router).
    Once you confirm the settings (click Next), 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. 5.
    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.

    FOR COMPLETELY DEAD WRT54G's ONLY!!!Apparently you can force a dead unit to reset itself and accept a tftp upload by shorting pins 15−16 on the
    Intel flash chip when powering up.
    These pins are the ones near the LED with the white stencil marks on a WRT54G V2 unit.
    On a 1.1 unit you need to count the pins.

    I have tried to set up a static ip and ping the device using the instuctions as above but that doesnt work either. It just comes back as failed.

    Sorry Im not very good with electronics could anybody please explain to me in a bit more detail how exactly to short the pins. I have a v1.1 and you say I need to count pins??

    Could do with some easy guide if there are any.

    Cheers, thanks for your help, much appreciated

    1) Rename the file to "code.bin."
    2) From the same directory the firmware resides, type TFTP -i PUT code.bin at the command prompt.
