As of July 2010 you can only use the trailed builds with the e2000 name in it for initial flashing and nothing else, using other bin's without the e2000 name in it for initial flashing may result in a bricked unit! After you have dd-wrt installed to your unit, you can then use the e2k-e3k.bin's for upgrading to newer builds.

  1. Disconnect all cables and wireless clients.
  2. Do a 30/30/30 reset on router.
  3. Connect 1 Lan cable to pc doing the flash.
  4. Log into Web Interface and flash the firmware
  5. Wait 5 minutes until WAN light turns on.
  6. Power cycle by unplugging E2000 for 30 secs.
  7. Plug E2000 back in and wait about 5 minutes until it finishes booting.
  8. Do a 30/30/30 reset on router.
  9. Wait 3 minutes and log into web interface.

DD-WRT E2000 Build information

The latest builds for this unit can be currently found in the FTP. Support was added in 14826 and on.

Brainslayer added E2000 Support from 14929 and on and builds are to be found in the broadcom_K26 folder of his build branch.

Also it has been asked about the builds with e2k-e3k name in them, these builds are for if you already have those units flashed with dd-wrt, you can simply use one of those builds to upgrade, but the initial flash should always be done with the trailed build (build with the unit only name in it) linked above.

If dd-wrt is already on the router follow these instructions. If stock firmware is on the router follow the flashing instructions.

  1. Check for recommended builds here first.
  2. Set your computer to a static IP of (or to whatever subnet the router is on) Disable all firewalls and security. Disable wireless on your computer and only have the router connected to the flashing computer by the ethernet cable between the two.
  3. Hard reset or 30/30/30 (If the router supports it, if not, reset to defults in the GUI) prior to flashing. Wait. Check for password page on re-login and change password.
  4. Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
  5. least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
  6. Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
  7. Wait for the lights to return to normal usually about 2 minutes.
  8. Hard reset or 30/30/30 again (If the router supports it, if not, reset to defults in the GUI). Wait. Check for the password page and re-login to change the password. Then you can reconfigure your settings manually.
  9. Once configured set your computer back to autoIP and autoDNS.

Important1: This Hard reset or 30/30/30 works fine for Asus router, but you do have to power cycle after the reset.

Important2: After you flash the firmware, and before you do the hard reset, the router will be building some nvram settings. YOU MUST WAIT FOR THIS TO FINISH PRIOR TO DOING ANYTHING WITH THE ROUTER INCLUDING A HARD RESET. Usually, you can tell when this process is completed by the WAN light coming on, but it does take several minutes. Go have a beer. There are starting to be more and more people who BRICK their routers by not waiting until the nvram is rebuilt, PRIOR to doing a hard reset. YOU NEED TO WAIT!


To revert back to stock firmware from dd-wrt do the following steps.
  1. Go to Linksys support site and download the latest stock E2000 firmware image.
  2. From within the dd-wrt webgui go to Administration > Factory Defaults, and reset to factory defaults.
  3. Once you router has reset to factory defaults, set a static ip on your machine to and access the webgui @
  4. It should prompt you to set a user/password, do so, then from the webgui, go to Administration > Firmware Upgrade
  5. Select to reset to defaults on the drop down menu and then browse to the stock firmware image for the E2000, select the file and flash.
  6. Wait 5 mins from flashing, then do a 30-30-30 reset and login again @ and begin your config on stock firmware.
  • Should you want to use DHCP you will need to then unset your static ip on your machine.

Just a note on upgrading e2000, e3000 and e4200 routers already running dd-wrt. These need -nv60k.bin builds, but this will work only from now on. So for initial upgrade use proper mini-eXXXX.bin build and then upgrade with -nv60k.bin build.

Some useful tips

I have noticed with these style of linksys units, cooling can be very important to its performance, thus I have done a nice easy mod that will allow air flow for under the unit. Check this post for details. -buddee

Also there are problems with the wireless LED using the above build, you can however upgrade to this build, which fixes the LED problems, you can do this after and only after you flash with the above initial flash procedure. The build within this post (14974) is not for initial flashing. -buddee
