Flashing

NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power.

Flashing dd-wrt

WARNING: DD-WRT Support for this device is Work In Progress (WIP). Test builds should only be flashed by experienced users. Test builds could cause unseen side effects.

WARNING: Requires K2.6 for DD-WRT, Do not flash anything else!

On the DDWRT Wiki
On the DDWRT Forum
On the DDWRT Forum
Support started version: rt-n15 build 16023 20110113
Current supported version: ?

The device is stitched from windows Firmware update in an official insertion (the version of an insertion 1.0.0.7)

Firmware files can be found here: Where do I download firmware? (asus-rt-n15 folder). Use the factory-to-ddwrt.trx to flash from Factory firmware to dd-wrt.

Flashing OpenWrt

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram. DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details.

This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation. This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

OpenWrt support for this device has ended in 2022.
19.07.10 was the last official build for 4/32 devices.

Upgrading

Upgrading dd-wrt

Firmware files can be found here: Where do I download firmware? (asus-rt-n15 folder). Use the asus-rt-n15-ddwrt-webflash.bin file to upgrade dd-wrt to a newer version.

Reverting

Reverting dd-wrt

To restore the device to factory firmware, you need to put it in Recovery Mode.

Download the factory firmware
In dd-wrt, reset to factory defaults, through the GUI or CLI.
Disconnect everything from the router, except the power cord.
Push and hold the Reset button with the router powered on. Without releasing the Reset button, unplug the router.
Wait until the power light starts blinking, then release the Reset button.
(Not tested, most likely access a webpage at 192.168.0.1 or 192.168.1.1) We launch program Restoration Firmware, we select a file with an insertion, we stitch.
(Not tested) Browse to the factory firmware file. Click the Upload button.
(Not tested) Wait at least 5 minutes before touching the power cord.
(Not tested) Do a factory reset once the router comes back up successfully.
