Netgear WNR3500L

From DD-WRT Wiki

The WNR3500L (v1) REQUIRES a K26 build from a /broadcom_K26/ build directory. All of the K26 builds have "_K2.6_" in the filename. Also be sure not to use a build greater than 7.3 MB, which may brick your device.
This wiki is NOT for the WNR3500Lv2 which uses K3X builds.

See: Firmware FAQ

Which Firmware?

First you need to know that this router only supports the "NEWD-2_K2.6" firmware. Next, you need to know which revision number (i.e. build 13525) you want to use. For recommendations on what revision to use, don't trust the Router Database. Instead you should first read the Peacock Thread keeping in mind that this router REQUIRES K2.6. Pay particular attention to Note 3. Then read the Firmware Recommendations Thread (still keep in mind K2.6). You should now have a pretty good idea of what build number you want.

Now you need to know what build version you want. Compare the features of the different build versions here. This router has 8MB, but due to Netgear's partitioning, the available space is reportedly ~7.3MB. Do not try larger builds. See Where do I download firmware? for links.

Installation of DD-WRT from Netgear Firmware


  • The WNR3500L requires K2.6 builds of DD-WRT (Update: see "K3X builds")
  • First download a trailed build .chk to flash to the router from Netgear factory firmware.
  • Once running DD-WRT, the .bin builds can be used
  • Research the forum for "New Build" and router model threads before selecting a build.
  • dd-wrt.v24-21061_NEWD-2_K2.6_mini-WNR3500L.chk has been reported to work for initial flash


  • Set a static IP such as on the PC you will be using for the flash.
  • Connect the PC to the router's LAN port (recommended to unplug everything else)
  • Perform a hard reset on the router.
  • Go to
  • Cancel the router's automatic firmware update checking, then click on "Router Upgrade" in the left menu.
  • Upload the special .chk firmware file.
  • Wait 5 minutes after the router says it is done
  • Perform another reset, and clear the web browser cache between updates.
  • Repeat steps 4-7 with the .bin firmware file.
  • Login and start tweaking

Reverting back to factory firmware

For now this is a WIP, but in the interim, you can simply follow this guide to revert back:

K3X builds

There are some K3X builds that have been reported to work on the WNR3500L: K3X 33555 Mega works

  • If you attempt this, only flash when already running DD-WRT (there is no trailed build in K3X)
  • The router name doesn't recognize the v1, so reports "Router Model: Linksys WRT54G/GL/GS"
