DD-WRT is a Linux based alternative OpenSource firmware suitable for a great  variety of WLAN routers and embedded systems. The main emphasis lies on  providing the easiest possible handling while at the same time supporting a  great number of functionalities within the framework of the respective hardware  platform used. 
 
The graphical user interface is logically structured, and it is operated via  a standard Web browser, so even non-technicians can configure the system in only  a few simple steps.
 
Apart from the simple handling, speed and stability are also in the focus of  our development work. Compared to the software preinstalled on many WLAN  routers, DD-WRT allows a reliable operation with a clearly larger functionality  that also fulfills the demands of professional deployment. 
 
The huge user community gives support to DD-WRT developers and the users  themselves in various ways. Thanks to this, potential flaws in the system can be  detected very quickly and can thus be corrected without delay. DD-WRT users can  find help and suggestions from other users in the user forums, and the Wiki  containing further information and how-to guides is being expanded and  maintained by the DD-WRT community as well.
 
For devices mainly used for private purposes, DD-WRT is freely available.  Platforms used for commercial purposes require a paid license. Compared to the  freely available version, the professional version also allows for configuration  of the WLAN parameters, thus opening up the opportunity of creating e.g.  reliable and powerful network infrastructures. Special demands can be fulfilled  by specifically tailored versions of DD-WRT.
