Bricked your WRT54G Router?

03 Dec

Here’s some instructions that will help you and they certainly helped me get my bricked wrt back in the swing of things:

you don’t need to register for that:)

it sounds like the firmware upgrade has gone wrong or the firmware itself was corrupt.

assuming you have windows XP these instructions can be generic.

1. Go to Start click on Run and type in control ncpa.cpl

2. Double click on the Local Area Connection that controls your network card.

3. Click Properties under Local Area connection status.

4. Click the Configure button. Then, click on the Advanced Tab.

5. 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”.

6. 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.

7. Click OK after you made the change then click Close

Reloading the firmware

get a new version of the correct firmware you need first of all.

1. First, hold the reset button located on the back of the router for 30 seconds.

2. 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.

3. Type ping and press [Enter]

4. You should get the following results:

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

5. Once you get these replies, close out of the command prompt by typing in exit and pressing [Enter].

6. You may now proceed to upgrade the router’s firmware with the files that were downloaded.

7. Once the upgrade is complete, the router’s Power light should no longer be blinking.

    I tried the steps above and I still couldn’t ping the router.

    The problem was dhcp wasn’t up on the router which I just flashed yet. I changed the IP address on the PC network card (on XP under the network cards properties I went into the properties of “Internet Protocol (TCP/IP)” and selected “Use the following IP address” and set the ip to, the subnet mask to and the default gateway to

    After I saved this I was able to ping

    In the event your router is giving you real trouble, and you’re not getting a return ping with the above method, I found this to work… combined with the above resetting method:
    1) Try removing the power cable
    2) Plug back in the power cable, and ping *exactly* one second after you connect the power. (Counting “one mississippi”/”one one thousand” should be close enough)
    3) You might get some of the ping results returned, and some failed. That’s ok.
    4) Unplug the router, get the tftp command ready. Plug the router back in and press enter to run the command *exactly* one second after you connect the power.
    You’ll know if the tftp command works because it will tell you the transfer is successful. If it doesn’t, try again, but you’ve got to be pretty quick. Good luck!
