Which "the user manual"? Which "the menu"? Visit
http://netgear.com/support , put in your model number, and look for
Documentation. Get the User Manual.
If there is no Setup > Wi-Fi Multimedia option (as described in the
User Manual), then firmware updates may have changed the options. Can
you find anything about "Quality of Service" or "QoS", instead of "WMM"?
A cable-TV ISP has complete control over the firmware of any
modem(+router) on its network. It's also possible that your ISP has
disabled such features.

I've read things, too, some of which were more useful than others.
