Ender3rd : At what point are you supposed to sacrifice a chicken during this procedure? Seriously, non-volatile ram does not magically re-assert data after the first flush! One data clear-out is certainly sufficient to allow the new hex structure of a firmware upgrade to flash without old settings re-appearing. This looks like someone is having a good laugh at the thought of people "flushing" their RAM 9 times for absolutely no reason. Follow the manufacturer's suggested procedure and your firmware flashes will proceed without issue. Mine always have. The suggestion about using a UPS is an excellent one and very valid as a power interruption at any time during a flash can make for a challenging recovery adventure.

NVRAM is non-volatile random access memory. Fancy words, but it is just memory that doesn't lose it's information when the power is turned off. Going through all such gyrations is absolutely not necessary UNLESS the firmware has been corrupted and needs to be re-flashed. It is unlikely that the device would run at all if the firmware was corrupted.

It works and doesn't harm the router. All brands it works on. I've tested go figure.

I have ten DLINk Gigabit switches, a Dlink access point, a couple of Dlink Bridges, a DGL4500, and the Actiontec router. they are never turned off. All my electronics are on a UPS. All of the network equipment is covered for 15 to 20 hours during a power outage. I never turn them off and never reboot unless necessary like during a firmware upgrade or to get a new IP address. Otherwise I have no other reason to reboot.
I would never turn that equipment off, since I have around 50 devices on my network and there is always a device that needs internet access at any given moment, especially my alarm system.

Well everyone going to have different setup. You're running SBS right or small domain, average home using not going to be running such a complex system. I mean I come close to you in switches.

taytong888 : Thanks tipstir, I will give this a try. As for how I bricked the Asus router, when I first flashed the router I must have been too impatient to do the 30-30-30 properly. Then I spent a few hours playing with the reset button and got it working as a non-DD-WRT router. After that I flashed the DD-WRT firmware and it was working fine. Recently I switched to the modified Trendnet and had to unplug the Asus. When I tried the Asus again, all lights went on despite no cables being plugged in. That's why I believe it has been bricked and asked you for the correct procedure to "unbrick" it. Hopefully this time I will work more slowly but correctly. Sorry for the long explanation.

Browser set to the default IP use when you first got the router. Reset the router press in the pin in the rear for 40 seconds then release and keep on access the default IP through the browser. Has to be timed just right. Once you get in flash the router back with the orginal one. I did on the trendnet it worked.

That's silly. If there's no power to the unit, you can hold the button, not hold the button or stand on your head and wiggle your ears and it won't make one damned bit of difference.

I think this whole thing is more superstition and rumor than science. Resetting a router to defaults after a firmware upgrade is a good practice. Re-loading an old configuration can be problematic if the newer firmware contains features not anticipated by the previous configuration. Any manufacturer worth their salt will call this out in the release notes and advise when to reconfigure from scratch. The rest makes no sense to me.

If I'm wrong and all of this folderal is needed to make a D-Link work properly, I'd be shopping for a different router.
