This will allow you to make the first WIFI and if necessary the first update of the device (it takes 2 to 3 minutes).
Be sure to change the router's password and note the new manual or in a safe place.
Note that this is a router, it does not replace your modem / internet box, but it connects to it.
The quality is correct, however it is a very lightweight device, allow slack in the cable networks, in which case the router will lugged / pulled back or even will not touch the floor / cabinet.
Also note, if the router is installed in a room quietly taken its sizzle quite strongly when the unit is subjected to intense traffic (less at rest).
Also in the minor inconvenience if the router is in a bedroom for example, the front LEDs are very powerful, it may possibly disturb.
Apart from these comments, the router served its purpose. For info if it can help some, for my personal use of this unit, the WiFi is used for mobile / laptops and RJ45 ports for TV, Xbox 360 and PlayStation 3, and everything works correctly and without loss of speed with respect to the internet box.
(Edit to 1 July 2014: now an Xbox 360, Xbox One and PlayStation 4 are connected to the RJ45 ports, everything still works as well.)
PS: The application Netgear Genie Android (available on other platforms I think) works without problems with this router.
