'Download Master' not available on DSL-N55U router options despite showing on Asus doc website

Question

Despite the fact that the Asus FAQ says that the 'Download Master' feature is available in Firmware 3.0.0.3.X and above ...

http://support.asus.com/FAQ/detail.aspx?SLanguage=en&m=DSL-N55U&p=11&s=2&os=&hashedid=aOKU9r3fCf3pyi95&no=3AA2723A-1A11-92FC-6D18-475703AA1F65

And the version on the router is 'Firmware Version:3.0.0.4.188' (the latest one)

The option of 'Download Manager' (as seen in the YouTube video linked from ASUSs site above) is not there - theres a new option 'Media Server' that isn't in the video - but no Download Manager.

Can anyone assist with getting this feature running please?

Answer 1

Turns out there are two chip sets for this model - and some of the features are not released for one the chip sets. (They are available in the beta version though).
