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 (with the button on 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.

Build Notes

- This is otherwise a very good build for this router.
Unbricking
Contrary to the advice in Peacock, this router can often be recovered by shorting pins as described here if you have managed to brick it:
- 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.
- Then 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
- Factory Reset DD-WRT (with the button on the back)
