I have the same router and found I couldn't connect wirelessly when I first set it up. What I had done was to install the drivers and then let the Netgear software set up the connection. Tried it several times and it just would not work.
In the end I uninstalled everything and started from scratch, but once the drivers were installed I chose the option to let Windows set up the connection instead of using the Netgear software, and lo and behold, everything worked.
That was all on XP, Vista may be different. Oh yes, one other thing I found with the Netgear installation software - it messed up the XP logon screen, removing the list of users and replacing it with a bald logon screen. If you get that,
this link will take you to a site where you can download a program to fix the problem (assuming you want to of course).
