ASUS RT-N66U firmware flashing problem

post #1 of 2
Thread Starter 
So I recently had to purchase a brand new cable modem and router due to a lightning storm. Since last Friday I have been getting constant disconnects in internet on the computers directly plugged into the back of the router. Whereas any computer connected wirelessly has working internet. Long story short, I isolated it to being a DHCP issue in the router so I attempted to flash the router's firmware with Shibby's Tomato firmware (http://www.shadowandy.net/2012/03/asus-rt-n66u-tomatousb-firmware-flashing-guide.htm). As per instructions, I manually set my static ip to 192.168.1.12, subnet mask to 255.255.255.0, and default gateway to 192.168.1.1. I then powered down the router and opened up Asus's Firmware Restoration Utility and loaded in the Tomato firmware file. Following this I held down the reset and powered on the router to engage the emergency firmware restore mode. I started the firmware flash procedure and when it was finished I was greeted with a message which says:



Now I'm unable to connect to the router at all. If I plug back in an older Netgear router I get working internet (still using the static 192.168.1.12 ip).

These are what the settings look like when I plug my computer into my old working router.



I am at loss here. Did I brick my ASUS router? Any help would be much appreciated. Thanks.

Check to see if you can reflash it. It seems like just a bad flash. Try a different ethernet port...

Your router needs to be in firmware flashing mode for it to flash properly.

If DHCP was an issue I would have troubleshooted it by turning off DHCP first instead of resorting to aftermarket firmware tongue.gif

You should also check to see your modem settings are right; it seems like they are since the Netgear router works.

Did you follow these parts? It seems like you did.

Putting the RT-N66U into emergency firmware restore mode

Press and hold on to the reset button
While holding down the reset button, plug in the power cable so that the RT-N66U turns on.
Note: Keep holding the reset button until the power led starts to flash (on and off). When power led starts flashing, release the reset button and proceed.
On the firmware restoration utility, agree to the prompt saying that it is a incompatible firmware.
The utility should be scanning for device. Quickly proceed to the next step
Wait until the flashing is complete
Power cycle the router when it is complete

Clearing NVRAM via key presses

Power off the RT-N66U
Press and hold down the WPS button
While holding the WPS button, plug in the power cable to turn RT-N66U on
Keep holding the WPS button for 30 seconds before releasing
The router should reboot
Congratulations. The NVRAM has been cleared.

Side Story: My brother took a Cisco networking class and thought he was pro at networking. A few years back he tried to flash a Linksys dual band router (my father had bought it for ~$120 at the time I think) to dd-wrt and basically bricked it due to haphazardly installing the firmware via wireless (lol?). So "bricking" it (softwarewise) is possible but unlikely via ethernet.

I don't know if that is of any help, I hope it is.

By flashing firmware I think you voided warranty , not that ASUS warranty is known for being stellar tongue.gif.

P.S. you should erase your Windows username from the screenshots since your name is in it...
