The Netgear Router works as advertised by the vendor. But the router has more features which are not available (as the UI built by Netgear is limited in functionality).The router can be used as a repeater or a wireless client (to extend range of your wireless network). This does not require any firmware change, but just one utility from Netgear to enable shell access and to execute few commands (may sound like Geeky, but simple enough for a 10th grader to do).The advertized features work for all the versions of this router (this router has version 1 to 7 till date), but the hidden features may work with specific set of versions only.
