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!
2https://superuser.com/questions/806656/finding-the-ip-address-of-a-walled-in-router really similar - though I went through a lot of effort trying to find its IP address - and the process might help. A reflashed DDWRT instance should have default settings so the fact you turned off DHCP shouldn't matter – Journeyman Geek – 2018-08-12T07:49:02.677
@confetti I have tried a 30/30/30 reset multiple times to not avail – Kevin FeDex – 2018-08-12T13:44:00.803
@JourneymanGeek is right, when I flashed my linksys everything went back to pretty much default, with the default IP being
192.168.0.1
or192.168.1.1
. – confetti – 2018-08-12T13:48:13.307@confetti neither of those work unfortunately, any other ideas? – Kevin FeDex – 2018-08-12T14:09:27.300
@confetti or maybe you can explain how I can go about flashing the router? – Kevin FeDex – 2018-08-12T15:54:18.637
Follow the instructions here - That's basically what I did for my model and it worked straightforward.
