Procedure:

Get Internet connection working:

First, before you start, the wireless controller must have a working internet connection.
To achiveve this, make sure that DNS Server and Default Gateway addresses for your network are set correctly on the controller, under Configuration >> System >> IP/VLAN :

You can verify that the connection is working with the Diagnostics >> Ping page. Try to ping netgear.com, for example.

To retreive the licences that are assigned to your WC7600: (WC7660SKT)

1. Log into your controller, and go to Maintenance >> Licencing >> Licence >> Advanced in the interface:
   
2. Press the Replace button.
3. The key(s) should populate and Key Status should come up as Registered and will also show up on the Inventory tab as well.
   

Notes:

• The controller comes with a 2 Access Point (AP) evaluation licence, so you can test the system, but that evaluation licence will expire when you apply the first purchased licence.
• You can apply up to 50 AP licences per controller, Licenses come in 10 or 50 AP packs. Also, you can stack 3 controllers to control up to 150 APs, when fully licenced.
• If your WC7600 is replaced under warranty by Netgear, you can use this same process to retrieve your licences on the replacement unit.
