Power went out during upgrade. Can't ping router, can't connect to any of the ethernet ports(windows says cable is disconnected, but I know cable is good), so basically when I set the static IP (192.168.1.1) it won't connect to router. Asus Firmware Restoration can't find router. Need help here.

Peacock announcement, note 6. You probably need a serial cable to fix it.

Just curious, what model router is it?

Some ASUS models have a recovery mode built directly into the CFE... and as long as the CFE wasn't compromized you should be able to debrick without a serial or JTAG.

Edit: Wow.. that was a dumb question. =p

Let me see if that model has a recovery mode. One second.

Try this..

http://dd-wrt.com/wiki/index.php/Asus_RT-N66U#Upload_Firmware_via_Recovery_Utility

Reading through the rest of that might be a good idea as well. Smile

Unless of course that's what you tried with the Asus recovery software. I've never used it, and have no idea what the procedure is for it.

Okay i know this sounds stupid..........
But i had this issue to, what you need to do is set a static ip like this

IP 192.168.1.2 you can try higher numbers it doesnt matter
Subnetmask 255.255.255.0
Gateway 192.168.1.1

Erase your NVRAM before you go to recovery mode

30 sec WPS button while on keep in pushed while the router is off for 30 seconds keep it pushed and turn your router on for 30 seconds.

When you did that put the router in recovery mode, start a CMD and '' ping 192.168.1.1 '' if the ping responds quick fire up the recovery tool and flash the original asus 220 firmware.

AFTER all of that ERASE your nvram before you try to connect to your router and also delete the static ip and stuff from your computer else you cant connect to the internet.

I know this is a bit messy but this is the only way for me that i actualy works.

Recovery will probably tell you that the flash went wrong, but that isn't the case !

Recovery utility cant ping the router because you had a static IP and the router did not accepted it.

I am willing to help you i think your router is not bricked unless you messed with the CFE please give me a PM and i will look what i can do for you

Router's LAN ports are not dead. I found a traffic analyzer called 'Wireshark' and when I turn router on it shows a lot of activity on the network, but I still can't obtain ping reply from router.

P.S: You can see a 5 minutes video introduction to Wireshark here:

Try to ping the router while starting it up and save a .Pcap file to upload it. We will be able to help maybe.

The .pcap file was saved from Wireshark 1.8.3 64 bit.

- lfbb

EDIT:



What does line 5 mean? That router's IP is 0.0.0.0?

I've noted something very strange in my Ubuntu 12.04 LTS virtual machine... The Network settings show the router is connected. Does this mean I can do something from the Linux VM?

You have your IP address set to automatic (DHCP). You should set it to
ip 192.168.1.12
netmask 255.255.255.0
for example

And the only traffic I see on that capture is yours, router is not talking at all...

About your VM, that´s a virtual interface which is comunicating to your host, not to the router I guess chequing the IP address.

Sorry, but I disagree. I've made a test in Wireshark, I waited 5 minutes with the router off, no traffic at all, zero. Then I turned the router on and the traffic started, so the LAN ports are not dead, but can't reply to pings. Very strange.

Anyway, thanks for your effort in helping me, I really appreciated it.

The 169.254.210.18 address indicates that the router DHCP server is not running. Looks pretty bad. What can I do more?

Set your IP to 192.168.1.15 netmask 255.255.255.0

Then take another capture with wireshark when powering on the router, holding the reset-button (just to get into recovery-mode).
