The 30-30-30 Hard Reset Rule for Routers

By March 11, 2009

Follow me on:

Essentially all broadband routers used for home networking provide a reset switch, often a very small, recessed button on the back of the unit. This button allows you to override the current state of the device and restore it to the default settings it had when it was first manufactured.

Some people don't realize that pressing a router's reset button for just a second or two may do nothing. Depending on the type of router and its current state (including the nature of any problems it may have), you may need to hold down the button longer. Networking enthusiasts have developed this so-called 30-30-30 hard reset procedure that should fully reset any home router to its default settings at any time. Follow these steps to perform a router hard reset:

    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
After this process (a total of 90 seconds) is complete, your router should be restored to its factory default state. Note that your particular router may not require the full 30-30-30 procedure. For example, some routers can at times be hard reset after only 10 seconds and without power cycling. Nevertheless, I still recommended memorizing this 30-30-30 rule as a general guideline.

read any supplied materials that came with your particular model. For example, My old Asante friendlynet required a jumpered reset.

Great advice. Worked on my Linksys wireless router after being unable to access the default IP address to change its config setting. The 90 sec procedure fixed a problem I had been working on for over an hour. Many thanks

Yessss it works!
My wrt54g was in a cyclic reboot mode and this method just un-bricked my router !

Tried the 30-30-30 on my Linksys E2000 without success. All I get is the flashing power (blue light) in bottom right hand corner of device. Tried 3 different cables between cable modem and Desktop (as well as laptop) to confirm cables work. When I connect cables between router and computers, I get no internet.

So I was trying to update the firmware on my E3000, and at 98% complete it failed. I have not done anything yet but I’m about to try your instructions to see if it works. Right now I can still access the internet, but I cannot access the admin screens. I can still ping the router too.

Before I do anything, I need to hunt down a TFTP client. I will also try these instructions (http://www.lancelhoff.com/how-to-fix-a-bricked-linksys-router/) if the 30/30/30 doesn’t work.

The 30/30/30 trick worked like a charm.

When the router came back up, it was at the firmware version that I was trying to update it to when it locked up.

Thanks for the post!!

Mine won’t work. Tried the hard reset. Didn’t do anything.Except for a few sparks when I plugged it back in. I guess the ice pick I stabbed it with was shorting out.

FYI: On the Linksys E2500, the reset button is on the bottom. Kept hitting the refresh button on the back of the router until I realized what I was doing wrong.

I have netgear Prosafe FSM726V3 manageable switch. I have tried to update its firmware. But it failed at the last moment. Then I rebooted the switch from Web login. But that was its last reboot. After the reboot, switch lights never became green. Its still yellow. And its not working right now. I tried to reset it by pressing reset button and 30-30-30 sytem. Nothing worked. I think its buil-tin O/S is damaged…. Is there anything I can do?

I have a BEFSR41 model Linksys and at least once a week I cannot access internet without unplugging and plugging it back it.

I’m a senior so make the answer easy. LOL

Don’t think this came thru first time. I have a Linksys router model BEFSR41. at least once a week I can’t connect to internet without unplugging and plugging back in the router. Any suggestions? I’m a senior so keep it simple. LOL

I know the famous rule 30/30/30 from DD-WRT pages when I had changed firmware from original Linksys to DD-WRT. But my doubt is as follows: first and last 30 seconds intervals are understandable (press reset button during power is on and still holding reset button while turn on power), but the second 30 seconds interval is questionable. The reason is as you wrote (or better guys from DD-WRT wrote)

2. while still holding down the reset button, unplug the router from power and hold for an additional 30 seconds

The only moment (and short moments after) during unpluging power or supply voltage could be important when microprocessor has still enough supply voltage and can execute power interrupt routine. Later on because the router has no supply voltages the microprocessor inside can’t do anything and is pointless holding pressed reset button for another 30 seconds. But as general rule it’s acceptable.

My router is Linksys WRT 160NL.

Trying the 30-30-30 reset, still unsuccesfully.
Some one can HELP me, need the ASUS for Printing thru the USB port.

I used this rule to reset my modem because I keep getting unsolicited calls from telemarketers and I have a new unlisted, number that third party and collections can’t call. But they’re able to call anyway. I believe it’s because they have a digital lock on my modem. I told Time Warmer about it and know this is why they’re able to call me even after changing my number three times and having every block imaginable on it. So, I did this to reset my modem. Hope it works.

Unbelievably, It sounds impossible method to rest router. However, I tried to reset it, but nothing method could until I used this.

Thank youu :)

I would STRONGLY recommend that you (as a rule) attempt a 30-reset, prior to a 30-30-30. For the difference between these, see this: http://www.dd-wrt.com/wiki/index.php/Reset_And_Reboot for the potential consequences, in some (less common) cases, see here: http://www.dd-wrt.com/wiki/index.php/Hard_reset_or_30/30/30

Yummy: If you just wasted 30 seconds you didn’t do it right. You should waste 90 seconds.

Just wanted to comment that some routers may need an additional power reset before the 30/30/30 “takes”.

By that, I mean to do the 30/30/30 & see if the router is functioning. If it isn’t, then unplug the power cable & wait a couple of minutes. Then, plug the power back in & try to access the router’s admin page again.

That’s how my Linksys E1500 works.

HTHs somebody out there. :)
