Huh, I didn’t know this was going on…As you might know, Linksys released the source code of the WRT54G firmware under GPL a while ago. Sveasoft (as well as other projects like WiFi-Box) took this code, added some features and patches and released an improved version of the firmware. This worked fine until one day, Sveasoft decided to close their firmware from public access and to charge 20$ from anyone who would want to download the code. So far so good, however since the GPL allows free redistribution of the obtained program (in this case firmware), one of their customers decided to put the firmware binaries on a P2P network, making them available for everyone. I don’t know who this person is, but I thank him for his kindness and in order to help people out, I decided to mirror those files on this website. Link.
