Hey mind sharing some more info on this. I am curious to know why and when this should be done as opposed to just flashing the new firmware.
thx |

| IMHO, should be done before and after flashing of new firmware. Or even just setting it up. It's just a way to make sure no settings get corrupted. I will have to say that if you do this, do NOT restore stuff up from a backup, unless you are backing settings up onto the same firmware version. If not, set it up from scratch. |

1 edit | Actually you should all put the wireless router, cable modem, switches, wireless access points, print servers on timers to shutdown at night where your sleeping. This way it can cool off thus save energy too. My cable modem works very hard I also reset that one flush out the NVRAM once every 6 months. After that it performs faster.
I control everything with one power surge strip, I should put everything on a timer. Flush out all the switches too. Say like 4am to 9am (5 hrs) shutdown.
Again the above is good when you have flashed the router so many times with different firmware. I just do this to make sure all the crap in NVRAM is gone. I didn't do it last time could explain why the N wasn't working. I'll do it with 1.31 firmware. It's a lot of work to bring down the network. |

| Tipstir, can you explain exactly what this does? How is it different from resetting the router to factory defaults (or something similar)? Also, what do you think would be the number of different firmware flashes to require the need for this method?
Thanks. |

Clears out the NVRAM, if you installed prior many prior firmware you want to make sure you got rig any older code left over from the prior firmware. So you want to start off fresh! |

I think your step B is a little confusing. I looked around and found these steps, which in my opinion are clearer and easier to follow:
1. when the unit is powered on, hold down its reset button for 30 seconds
2. while still holding down the reset button, unplug the router from power and hold for an additional 30 seconds
3. still holding down the reset button, turn on power to the router again and hold for 30 more seconds

I've found that the standard procedure clears the NVRAM quite nicely. You can also burn some candles and do a raindance for 90secs...... |

1. press the reset for 30 seconds
2. unplug the power while keeping the reset press for 30 secs
Not that hard to do.. It's the unplugging of the power then plugging in the power is what makes it confusing.. Just can't let go of the rest button while your doing the un-pluging and re-pluging |

| said by tipstir :Just can't let go of the rest button while your doing the un-pluging and re-pluging 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. |

said by No_Strings :Flash with new firmware. Hold reset button for 10 seconds. Done. The way I did was in the first post.. I didn't have any issues. Actually all my routers I do the same method.
There is a Recovery WebSite Flash Mode (Recovery Boot) or Recovery Emergency! Note You'll need to set your computer to the same subnet mask. Now you'll be given a page that will only allow you to upload the firmware. Upload your bin file and let the router do it's thing and you're set!
This is different way:
1. so the browser needs to be up and running.
2. Set browser to 192.168.0.1 (hard coded ip recovery)
3. LAN port 1 to PC LAN card connected
4. disconnect power
5. hold reset
6. connect power
7. hold reset for at least 30-40 seconds
8. connect to web browser 192.168.0.1 |
