Firmware version? Connected to what? Configured as a router or wireless access point?

"can't" is not a useful problem description. It does not say what you did. It does not say what happened when you did it. As usual, showing actual actions (commands) with their actual results (error messages, LED indicators, ...) can be more helpful than vague descriptions or interpretations.

Define "hidden". Does your "hidden" include "documented in the User Manual"?
Did you consider trying this radical concept (which works for some people):
I've never touched one of these units, so I know nothing, but a quick look at the WAX204 User Manual found some potentially interesting material.
That manual is a 246-page document. Did you expect _all_ of that material to be intuitive/obvious?
Visit http://netgear.com/support , put in your model number, and look for Documentation. Get the User Manual (at least). Read. Look for "isolation"?
The existence of a section title like "Manage client isolation for clients of the Wireless2 or Wireless3 network" suggests (to me, at least) that "Wireless1" might be different. Further reading might not hurt, either.
