Hi!

I crashed my WL500g with OpenWRT.

I tried to reflash the firmware with OpenWRT, it didnt work. How I get into Fail safe? there is no DMZ light as documented.

what i did for Failsafe:
pressed the reset button upto 5 and 10 second, and tried to get access from WAN port, but didnt work. cant  do ping either.

what should i do now? may be  i need a right failsafe sequence ?

Please, reply

Regards,

Try it from LAN1

Use ASUS firmware restoration tool to reflash firmware.

Thank you very much guys for your reply. I want to mention something here which is a bit contrast from given manual. In my case when I got into fail safe mode, I got telnet reply in LAN port rather than WAN(as it was written in documentation reply will be on WAN port). I am not sure about the exact time to keep the button pressed but anyways it is definetly a 10 sec or a bit longer.  According to documentation ASUS router should revert into the LAN ip address, which I set 10.10.10.10, but in this case it reverts into the defualt IP of router 192.168.1.1.

Regards and thanks.

I'm using WhiteRussian RC2 SquashFS on a WL500g.  I seem to be able to get it to go into Failsafe mode - I can see the PWR led flashing, and I can ping the router on it's LAN_IPADDR (192.168.107.1) address.  I can't ping it on 192.168.1.1 (I set my PCs interface to 192.168.1.2/24) and I can't telnet into it.  I've port-scanned it and there are no ports open - nmap reports all ports filtered.

I can't ping any IP address on the physical WAN port - but I had it unconfigured anyway.  I had the radio in client mode and it still seems to be in client mode when in failsafe mode because I can't see it pop up as an AP in a wireless network scan.

I can't get into the WL500g because I foobar'd the /etc/init.d/S50dnsmasq file.

I put

 args="-d -l /tmp/dhcp.leases -K -F $(int2ip $start),$(int2ip $end),$(int2ip $netmask),12h 2>&2 >/dev/null &"

in it instead of the usual args line.  I was trying to fix the dnsmasq bug described here and obviously got my shell things mixed up.  So now all the init files after S50dnsmasq won't run at boot - meaning S50dropbear doesn't get executed.

But in Failsafe mode, the router should ignore my edited file and use the one in /rom/etc/init.d/ shouldn't it?  And telnet should be enabled, right?

I'd rather not have to reflash the firmware if I don't have to, but right now it seems that failsafe mode has failed me.  Any suggestions?

Update:

The flashing PWR led isn't Failsafe mode on the WL500g - it's the firmware recovery mode.  If you hold down reset before connecting power, or immediately after, you go into a mode whereby you can upload a new firmware.  The router IP address is the LAN_IPADDR that was set by the user - so if you mess up that NVRAM variable you might be in trouble.

I ended up reflashing WhiteRussian RC2 SquashFS - it didn't do firstboot after reflashing so I manually rebooted it.  I wasn't able to telnet in straight away - I don't know why, but after reflashing I was able to get the WL500g into OpenWRT Failsafe mode by the usual method - rebooting, waiting about 3 seconds, and pressing the reset button for a few seconds.  The router's LAN IP came up as 192.168.1.1 and I was able to telnet in.  By doing a "df -h" I was able to see that firstboot had not yet run - there was no JFFS2 partition.  I ran firstboot manually and rebooted.  The router was is now back to normal - minus all the packages and configuration I had put on it.  I have found that after firstboot has run I am unable to put the router in Failsafe mode.  I have tried waiting various amounts of time after power-on, and tried pressing the reset button for various amounts of time but I can't get it to work.   The only conclusion I can come to is that for some reason, under WhiteRussian SquashFS RC2, Failsafe on a WL500g doesn't work after firstboot has been run - which sort-of defeats the purpose of Failsafe mode.   I don't have any more time to experiment with this, but I'd appreciate it if someone else with a WL500g could have a go at getting Failsafe mode to work.  And if you get it to work, please tell me how!

In the meantime, I'm going to get a USB-serial adaptor to work so I have a backdoor in case I foobar the network init scripts again.
