I was messing with my WRT54G running OpenWRT and I may have ruined it, but I am not sure.

By default, it has a static IP of, but I turned that off and made so it gets its IP from DHCP. After changing that setting, I cannot get to the admin panel, but I still see it broadcasting the WLAN. Pinging times out. I had it configured to use a custom hostname, but that address does not respond either.

I tried the following:

  • Using nmap to scan on to find where it is now (from a PC hooked up via ethernet), but nothing came up
  • Factory resetting using different methods from online, and nothing has reset it
  • Using the Linksys tftp utility to flash a new firmware image (but since I can't find the IP of the router, I can't do it)

Is it bricked, or am I doing something wrong? Is there a good way to find the IP?

Thank you for your time.

EDIT: As per Nic's suggestion, I made my router use another DHCP server (a second router) and could find the IP. I then restarted both routers and I can now connect. Thanks!

This question came from our site for system and network administrators.

Do you have some other DHCP server on your LAN? If not, try adding another router to act as the DHCP server then see if you can find your Linksys. – Nic Feb 5 '12 at 8:15
Ok, how can I do that? Should I just hook the routers up directly with an ethernet cable? – Matt Bell Feb 5 '12 at 8:17
Yes, just connect the LAN ports of two routers together, then connect your computer to a LAN port on either router. – Nic Feb 5 '12 at 8:18
Ok, I found the router and I can ping it, but I still can't connect. I did an nmap scan of it and no ports are listening. – Matt Bell Feb 5 '12 at 8:23
Maybe try TFTP again now that you know the IP address? That's all I've got though. Good luck. – Nic Feb 5 '12 at 8:24

The only solution I know is to make a 30/30/30-Reset. The IP was resetted in all routers I had. ( Maybe you want to flash DD-WRT right afterwards.
