Currently I have not done much with this router as it is my main connection to the outside world. Now that I have managed to get back into my Livebox I will look at making some changes to this router. What I have done so far is,
Built a new version of firmware based on the source released by Belkin, but I haven't tried it yet.
Tried some of the tricks from Skaya Wiki Broadcom 96345, within the Roadmap section.
