Have you ever did a firmware update while logged into the router through a wired connection?
I say wired because it is not a good idea to access the router through its wireless connection, because you can loose the wireless connection during the firmware update.
There is a menu with-in the routers firmware which checks for firmware updates from the NetGear web site, you should log into the router and try doing this, as it might have an update available that corrects this problem.
Just a quick add in here, the router's login is through a web browser and typing the following url http://www.routerlogin.net
this will pop up a box asking for the user name and password, if both are correct, your loged into the routers firmware.
