Important Notes
Only version 1 is supported. Versions 2 & 3 are not yet supported.
Use only K2.6 builds with nv64k in the name.
dd-wrt.v24-21676_NEWD-2_K2.6_mini-nv64k (and big) appear to be the latest build with working wireless.
Please note build size limits listed in peacock annnouncement. Some Mega builds might be too big
Recently (2014/05/31) tried flashing beyond this, to builds like dd-wrt.v24-24160_NEWD-2_K3.x_mega-WNDR3400.chk and dd-wrt.v24-23838_NEWD-2_K3.x_mega-nv64k.bin and met with failure (brick, had to pin-reset). So these instructions are current!
Read Peacock topic (at top of Broadcom Forum). Read it all. Carefully.

DD-WRT Installation
- There are two versions of this router with corresponding initial flash mini firmware. One is for Netgear branded routers and the other is for Cablevision routers.
- Do a factory reset (recessed button in the back), and upgrade with the appropriate mini firmware above. If it complains about downgrading, just Allow.
- To gain functionality of the usb port, upgrade to the big version or the mega version after flashing the mini version above.
- 30-30-30 reset router (as described in Peacock).
Build Notes
19342
- Big and Mega contain the Heartbleed vulnerability!
Use only Mini version of this build! - This is otherwise a good build for this router.
21676
- Upgrading to Big will brick this router!
Mega contains the Heartbleed vulnerability!
Use only Mini version of this build! - This is otherwise a very good build for this router.

Unbricking
This router can be "bricked" (rendered inoperable) by flashing the wrong firmware; by not following the correct flashing procedure (in Peacock); or by flashing a bad build like 21676 Big.
Factory method
See Reinstall the firmware on a router without the setup CD recovery tool
Recovery mode method
This method, which works on the WNDR3800, may also work on the WNDR3400v1.
Pin short method
If you have bricked your router, and you are willing to accept the risk of damaging it beyond repair (as warned in Peacock), the router can often be recovered by shorting pins as described here.
- Timing of the pin shorting is tricky -- power on, wait for the lights to flash, then try shorting a few times until the power light starts flashing steadily.
- Next use tftp2 (with no password) to flash factory firmware.
- After the flash, wait at least five minutes after the router boots up and the power light becomes steady green before resetting the router.
Here is another overview of the process for the WNDR3400 http://stevejenkins.com/blog/2014/01/how-to-unbrick-a-netgear-wndr3400-n600-router-after-a-bad-dd-wrt-flash
Revert to Factory Firmware
- Download official Netgear firmware
- Reset DD-WRT (recessed button in the back)
- Enable telnet under services
- Telnet to router (192.168.1.1)
- Issue the command "mtd erase linux" & wait ~3 mins
- tftp the official firmware to the router
- tftp for windows [1] enter router ip, leave password blank, select official firmware file
- 30-30-30 reset router (as described in Peacock)
