Topic: Bricked router ASUS WL500g-Premium ??

Hi there,

Today i have just installed on my ASUS WL500 Premium router, the Kamikaze 0.79 package. Everything went just fine. After that i have installed the X-WRT package for web interface. Again, everything went fine.

In the web interface i have changed in the Network > LAN Settings, from Static to DHCP. When i applied the changes, it took a long time and after that the web page just got blank. I have refreshed the web page but nothing. I have restarted the router and now i have an "Limited or no connectivity" message on my Local Area Connection. If i ping it to 192.168.1.1 i get an "destination host unreachable".

Even if i am putting it in the diag mode, it can't see the 192.168.1.1 address, so i can't recover the firmware.

Have i bricked the router ? Can anyone help  me ?

Thank you in advance !

your problem is that your lan interface is looking for a dhcp server. Either plug it into the LAN port on another router, setup a dhcp server on your computer, or go into failsafe mode on the router, or connect to it via a serial port, and fix the config.

i tried this but it doesn't work. i still get the "Limited or no connectivity" message.

This means that i should open the router case ? Because i don't see any serial port.

so the other router should have the address let's say 192.168.1.1, my ASUS should dynamically have 192.168.1.2, and my computer should have 192.168.1.3. Then i will connect from my pc with putty to 192.168.1.2 and try to make the changes. Am i right ?

Thank you!

when in failsafe, you must set your computer to 192.168.1.2 manually, since dhcp is not started in failsafe

the address assigned to your router from the other dhcp server is not in any specific order, it may be random within the range, or not. look at the router's logs, or arp traffic to figure out the router's ip address.

if you use failsafe mode, be sure to run mount_root when you first connect to the router (with telnet) to gain access to your filesystem

well, i did somehow restore the original firmware...more exactly the one from the ASUS site (WL500gp_1.9.7.5_TW.trx), but now i can't access http://192.168.1.1

later edit: I must say that the power led is blinking and the led of port 1 is on

hi,

you get 3 recommended options how to fix your settings (failsafe, set up dhcp-server, and serial-console). but you tried another one?
I can only say, that flashing to original firmware was not successful!
a blinking powerled means that the router cannot load the system and stays in the bootloader waiting for a tftp upload of a working firmwareimage. before this you had a router with a messed up networkconfig, and now you have a router no system on it.
You can try upload an image with tftp, if this fails you need a serial-console-cable (adapter from rs232toTTL) open the case and solder some pins to it and connect the serial cable.

@eleon216: a tad bit of topic, but what if all the lights on the router are off, what does that say?

it seems that i can only make the router to function, if i'm installing on it OpenWRT firmwares, like WhiteRussian or Kamikze. I tried to install te backup of my original firmware, the firmware from ASUS site and even DD-WRT, nut nothing worked. Only OpenWRT .... isn't it strange ?

Is there a way to format the memory of the router ?

hi,

I´m not shure, but I remember that there is a problem (limit) when flashing with tftp. I think you can´t flash images  that are bigger than 3 MB (or something like that). This could be the reason why you can flash openwrt, which is quite small, but no other firmware.
If you want to flash another image you have to flash it from a running system (in openwrt with the mtd-utility) and not in the bootloader trough tftp.

So I don´t think you need to format the flash, and I would be careful in doing so, because if you erase the bootloader, which is stored in the flash too, your only chance to recover your router would be a JTAG-Interface, which the WL-500GP don´t have, so you would need to desolder the flash-chip and reprogram it somewhere else.

and @Johnex: if all lights are off, your router has a hardwaredefect, or your bootloader is not working. you can try to connect through serial, and if this doesn´t work, your last chance is reflashing it with JTAG (if your router has a connector)
