Dd-wrt Default Password

[Mirtha Shikles]

Ahard reset sets the router back to the firmware's defaults, thus it will clear all the settings you have configured in the router. Here are some of the different ways that users are doing hard resets. Those methods will not unflash your router to the default firmware.They will reset to defaults such settings as IP address or password.

Holding down the reset-button while plugging in the router achieves a different goal than the thirty second reset. Here the bootloader is in charge, so getting it to clear the memory for you may have different results. Some platforms will completely empty the nvram and depend on another stage of the bootloader or firmware to repopulate it. On some less-supported hardware this may have unpleasant results, so use the following two reset methods cautiously.Note: On some routers, in particular a lot of Atheros based routers (and Asus), this may cause the router to go into recovery mode, instead of resetting the settings. It is often better to do a GUI reset, Admin tab, then factory defaults. Click apply and wait 5 min. The router is now reset and should ask for a password when you log into it at 192.168.1.1

To do a "hard reset for anyone not knowing OP or otherwise, hold the reset button with the power on, for 30 seconds, then while continuing to hold the reset button, unplug the linksys router, continuing to hold the red button in the back for 30 seconds, and while still holding it in, plug in the power again and keep holding the reset button for an additional 30 seconds. This will wipe the nvram out. Keep in mind with hard resets the linksys routers can be touchy I had to do it three times till it fully cleared out the nvram on mine" I think this forum poster actually meant that it will reset back to firmware/factory defaults, but as stated above, it could have unpleasant results "on some less-supported hardware".

Also called a Cold Boot, this means to remove power from the device for sufficient time to ensure all chip registers/voltages have cleared. Ten seconds off should suffice, but 30 is the norm, but if anomalies are encountered, leave the device without power longer. Ram has been known to be readable for minutes after a power off, and methods can be used to read said ram for hacking purposes. Chips have been known to maintain state for minutes as well.

Regardless, ram is supposed to be cleared on boot, yet there are various reasons why you can not be positive that this is the case. Design flaws, low cost design methodology, bugs in ram chips, can all result in ram or logic gates in chips, not being cleared on boot.

See Erasing NVRAM in the Hard Reset wiki for command line details.

To "clear, wipe, reset, or erase the nvram" commonly indicates "to reset back to the firmware's defaults", although the two terms do not mean exactly the same thing. "Factory Defaults" in DD-WRT really means "firmware defaults" because it reverts to DD-WRT's defaults.

I have flashed my Netgear 6400 with dd-wrt firmware and have made a configuration that reset button is disabled. However, I forget the original password after a few days. Are there any ways I can reset the password or get back the original password? Thank you very much.

I flashed my R6700 router with dd-wrt and was using it fine for quite sometime. I then wanted to revert back to the Stock firmware and tried to use the dd-wrt admin tab to update. Interestingly it did everything and rebooted but stayed back on dd-wrt.

Did googling around and tried various suggestions including the hard reset. Now at the end, I have this router powered on with various lights (no red), but doesn't show up as dd-wrt or netgear. Tried to hard wire to laptop and tried the tftp, can't send the firmware file to the router. Any other option?

Ok, at least I have established that my wifi is being seen as dd-wrt. But when I try to connect to it, it does not ask for username but only WPA2 password. The default after factory reset should be "password", but that does not seem to work in any combination, like "Password", etc. May be dd-wrt forum could provide some help?

Not a very detailed description of what you did. What file did you

try to load?

"tried the tftp" omits many details of a multi-step procedure.

"can't" is not a useful problem description. It does not say what you

did. It does not say what happened when you did it. As usual, showing

actual actions with their actual results (error messages, LED

indicators, ...) can be more helpful than vague descriptions or

interpretations.

I don't know how any of that works when non-Netgear firmware is

installed.

> [...] Any other option?

There may be a serial-port scheme, but it requires additional

hardware.

I uploaded, "R6700-V1.0.1.48_10.0.46.chk" via admin tab of the dd-wrt web interface. It showed it applied the firmware. However, after reboot it came back to dd-wrt web ui. I then tried the factory reset and also 30-30-30 method. They didn't make any difference.

When I tried to use tftp to upload the firmware to the router, it asked me for the router ip address, which I figured and provided after some ping test when the router was hard wired to mac. I then tried both "password" and no password. But I got the error as, "Error: No response from server".

When I look into wifi devices list on my laptop, it shows dd-wrt but that's not mine as even after disconnecting power from router, none of them disappear. No new one appears in that list when the router is powered back on.

hello my great friends!! hope u all have a great life...

i buy 2nd wifi router, buffalo whr-g125 about 1+years ago from lowyat.net member... he said the router had been upgrade to dd-wrt, but i dont know what version it is... the forumer phone number also i lost, the box he give to me also lost....

before this i always on the wifi function and installed some password but dont have the wifi device, only use the LAN function. now i have PSP and maybe will buy laptop with wifi enabled.

now i want to use the wifi function but forgot the wifi password... so what to do now? teach me about to reset the password without reset the dd-wrt, i dont know what dd-wrt but must buy it to install on my buffalo right? also how about the broadband paswword and its installation to this router? so all step will be resart from beginning? .. the default factory id and password and url at the back i cant acccess it.....

anyway thanks for the advice and ur time... see u soon

Hi folks,

Let me preface this with the fact that I know this is an old device and an old version, and the position of developers would almost certainly be that this is "not supported" and I should leave it alone. That being said, I have a use case for this hardware so I'm hoping to try to get it to cooperate.

I was recently given two TP-Link TL-WR703N mini portable wireless routers. IO consists of 1x USB micro-B for power, 1x 10/100 Ethernet to function either as WAN or LAN depending on configuration, 1x USB A female to accept a USB cellular modem, and integrated Atheros WiFi. These were configured by TP-Link with DD-WRT preinstalled, when new. The devices are used, but not by the person who gave them to me, and I figured my first step should be factory resetting them. They do not respond to the reset button when I try to follow the directions from the manual - e.g. hold button for 5-7 seconds - the device does not respond to this at all. I then considered the possibility they've been flashed with another firmware, and I've since been able to verify that at least one contains OpenWRT 12.09 Attitude Adjustment.

As the devices came to me, plugging them in to power gives a power LED that is briefly solid, then briefly off, then flashes for a minute or so, then goes solid. A host connected to Ethernet sees the port go up, but there is no DHCP response. No visible WiFi network seems to be broadcast. No type of interaction with the reset button seems to cause anything to happen at all; not a brief click, holding for 5, 7, 10, 15, 30, 60 seconds, rapidly pushing it repeatedly, absolutely nothing.

The power LED is solid or blinks slowly. A host device will lease an IP address in 192.168.1.0/24. The gateway is 192.168.1.1. The device does not respond to Telnet. Nagivating to this IP in a browser brings me to the LuCI web interface with a login prompt. The pre-filled username is root. I have tried many possible default passwords, including leaving it blank, but none are accepted. I believe the device is not in a reset state and the password is set by a previous user, but, does anyone have any suggestions for an unusual but possible default password? Maybe 12.09 didn't use a blank password by default?

The power LED blinks very rapidly. A host device will lease an IP address in 192.168.1.0/24. The gateway is 192.168.1.1. The device does not provide the web interface. Telnetting to this IP brings me to a BusyBox shell on the device displaying OpenWrt information, such as the version. It tells me to use the passwd command to set my login password which will disable telnet and enable SSH. I have an elevated prompt (root@(none):/#). I tried to set a secure password but am informed the file system is read-only.

I'm a little perplexed here. I'd very much appreciate any pointers that might help me get into this device. The second one is more challenging as I cannot seem to get either of the results above, it acts more like it may just be bricked. But if I can get one of these reset to some sort of defaults that let me in, I'd certainly like to do that.
