Installing DD-WRT On A Netgear WNDR3400V1 N600

The first task is to verify if you have a WNDR3400 V1, 2, or 3. I used this site to determine I have a V1 device. As the hardware for each version is significantly different, this procedure ONLY applies to V1.

According to what I found here (Sat Jun 11, 2016 4:06 post by mrjcd), the latest known good version of dd-wrt for this router is v24-27858_NEWD-2_K2.6. When going from stock firmware (as I am), use dd-wrt.v24-27858_NEWD-2_K2.6_mini-WNDR3400.chk.

  • Reset the router
  • Connect via Ethernet cable to the router’s #1 port
  • Access the firmware update page at using the default admin/password login
  • Upload the dd-wrt firmware
  • Wait for the firmware to upload and for the router to restart
  • Access the default dd-wrt Router Management page at
