[edit] CAUTION:

The WNR3500L (v1) is only properly recognized using a K26 build (in the broadcom_K26/ directory). See K3X Builds for more information. All of the K26 builds have "K2.6" in the filename. Also, builds must be smaller than ~7.3 MB, or you will brick your device. This wiki is NOT for the WNR3500Lv2 which uses K3X builds.

Read the Firmware FAQ and Peacock Announcement

[edit] Which Firmware?

The WNR3500Lv1 traditionally only supports the "NEWD-2_K2.6" firmware, but K3X has been reported to work. For build information and much more, see Where do I download firmware?.

Compare the features of different build versions here. This router has 8MB flash, but due to Netgear's partitioning, available space is reportedly ~7.3MB. Do not try larger builds, as this will overwrite required partitions.

[edit] Installation of DD-WRT from Netgear Firmware

Overview:

  • 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

Instructions:

  • Set a static IP (e.g. 192.168.1.8, subnet 255.255.255.0, gateway 192.168.1.1) on the PC for flashing.
  • Connect the PC to the router's LAN port (recommended to unplug everything else)
  • Perform a hard reset on the router.
  • Go to http://192.168.1.1
  • 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

[edit] 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"
