If you have bricked your router, and you are willing to accept the ''risk of damaging it beyond repair'' (as warned in [http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486 Peacock]), the router can often be recovered by shorting pins as described [http://www.dd-wrt.com/phpBB2/viewtopic.php?t=153763 here]. | If you have bricked your router, and you are willing to accept the ''risk of damaging it beyond repair'' (as warned in [http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486 Peacock]), the router can often be recovered by shorting pins as described [http://www.dd-wrt.com/phpBB2/viewtopic.php?t=153763 here]. |

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
- This is a good build for this router.
21676
- Upgrading to 21676 Big will brick this router! Use 21676 Mega instead.
- 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.
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 for at least a minute until the router boots up and the power light becomes steady green before resetting the router.
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)
