Restore possibly bricked WRT54GL (possibly lost IP address)

Recently I tried (and maybe succeeded) to install the DD-WRT open firmware onto my Linksys WRT54GL.

I downloaded dd-wrt.v24_micro_olsrd_generic.bin, placed it in the router's firmware upgrade area, waited 10 minutes, and then restarted the device.

I only have one issue. Right before I installed it I turned off DHCP. Now my computer recognizes a router "dd-wrt", however there is no Internet access and I am unable to access the web based utility.

Using ipconfig, the computer tells me there is no default gateway.

If anyone can help, it would be very much appreciated.

Ask if further information is necessary.

You need to do a 30/30/30 on the wrt54g series after any flash update.

Set a static IP address of 192.168.1.100, 255.255.255.0, default gateway 192.168.1.1

It's probably not "bricked", do the reset then open up a command prompt or terminal window and ping 192.168.1.1 continuously.

The Linux command prompt does it automatically. Windows it's "ping 192.168.1.1 -t".

While watching the command prompt, hold the reset button for about ten seconds, unplug the power while still holding the reset for about another ten. Release the reset with the power plugged in.

If the bootloader is there, you should see a ping response from the router for roughly 5 seconds. During this 5 second period the router will accept a new firmware image via tftp.

Make sure you are flashing a "legacy" or "VINT" mini image for the initial flash. After the successful flash you can put whatever image you want, STD, mega, VoIP etc.

The timing for the tftp transfer can be a little tricky. You want to have another command window open with the tftp command ready, watch for the first ping response as the bootloader starts.

You may have to try it a couple of times before it actually takes.

Don't forget, after any flash, do a full reset on these routers!

Good luck!
