DISCLAIMER: This process will overwrite the current stock ROM on your router. I have tested these steps on my own devices, but I am not responsible if you damage or brick your device. Verify DD-WRT will work on your router model before starting.
Flashing DD-WRT
- Open a web browser and go to https://dd-wrt.com
- Click the Router Database link
- Search for the model number of the router
- Download the DD-WRT Factory flash file
- Factory reset the router, this will differ based on the make and model. Reference the user manual or manufacturer's website
- Connect to the router's default wireless SSID
The default SSID(s), IP address, username and password information is usually stamped on the router chassis
- In the web browser navigate to the router's default IP address, usually 192.168.1.1
- Login with the credentials found on the router (or search online for the make/model default login credentials)
- Navigate the web UI to apply a firmware update
- Browse to the downloaded DD-WRT Factory flash file from earlier
- Wait for the flash to complete
- Connect to the DD-WRT SSID now being broadcast from the router
- Back in the browser, navigate to 192.168.1.1
