Congratulations! Please consider donating to DD-WRT as we are an open-source community providing free
software to upgrade consumer routers with commercial-grade capabilities.

speed out of your new N-Router.

Troubleshooting

IF the router won't provide a Power LED after updating to the K3.x file...then there is a problem with the flash
chip and it needs to be cleared (except the CFE). Issue the following commands via telnet/SSH or the
Commands window under the Admin tab.
mtd erase nvram
mtd erase ddwrt
mtd erase linux
This will clear the flash chip...now start the process again with the K2.6 mini build
This is documented here: [3]

Notes about K3X

Do NOT issue "erase nvram" command from CLI...this unit only has 64K of nvram...the CLI thinks it has
128K and the firmware thinks its 256k...this means doing an "erase nvram" removed other parts of the flash
chip (likely firmware partition "dd-wrt" or "linux")
Note: build 21530 seems to have wireless issues...it broadcasts the ssid...but you can't connect to it...however,
if in repeater bridge mode, you can contact it through the host AP at the router's IP address.
There is a large thread with lots of info on this router here [4]

Notes

NAT Loopback (Port Forwarding) is broken in builds 15760-19969 (see this thread for a workaround)
15962, 17990, & 18000 are Recommended Builds which would require this workaround
Special thanks to Eko for making the initial work on getting the RT-N16 to work with DD-WRT!

Upgrading DD-WRT

If DD-WRT is already loaded on your router, you can flash firmware using these steps
1.
Download firmware from one of the sites listed: Where do I download firmware
Go to the broadcom_K3X folder and download the ***K3.x-big-RT-N16.trx file.
2.
Open the DD-WRT's web interface in your web browser and open http://192.168.1.1/ (the default).
