DD-WRT: How to install the alternate router firmware
With DD-WRT you can install an alternative firmware on your router. The custom firmware extends the functionality of your router and has a simple web interface that is also available in several languages. In this article we show you how to get the open source system on your router.
DD-WRT: The preparations
Not every router is supported by DD-WRT. Therefore, pay attention to the following points so that there are no problems.
- Compatibility: Check the manufacturer's website to see if your router model is supported. For safety's sake, look at the bottom of your router, as there are often different versions of a device.
- Download firmware: With DD-WRT there are almost always two files. The first file "factory-to-ddwrt.bin" is responsible for the initial installation, the second file "-webflash.bin" is specially adapted for your router. Download both files.
- In rare cases, only one file is shown during the search. Then you only need this one file to flash your router.
- Factory settings: Restore the factory settings on your router. You can do this either via web access or via the reset button on the router, if your router has such a button. For routers from TP-Link you will find this point, for example, under "System Tools" -> "Factory Defaults". It is advisable to make a backup of your configuration before resetting.
DD-WRT: Flash firmware
Important: The following steps are at your own risk. The manufacturer's guarantee is void if an alternative firmware is installed. If there are problems during the installation, your router may become inoperable.
- First installation: At the beginning you have to open the web interface of your router. Most routers have the menu item "Upgrade firmware" in the system settings. Upload the first file (factory-to-ddwrt.bin) and confirm with "Upgrade". The upgrade may take some time. The router will restart in the meantime. Therefore, do not be surprised that no page is displayed in the browser.
- Web interface: You can reach the new web interface using the IP address "192.168.1.1" in your browser. Next you will be asked to change the username and password.
- Install customized router firmware: Go to "Administration" -> "Firmware Upgrade" in the router menu. For this you need the previously changed access data. There you have to upload the second file (-webflash.bin). Under "After flashing, reset to" select the entry "Reset to Default settings". With a click on "Upgrade" the final firmware is installed.
