OK, let's see. . . . Lots of steps to go through.
You do need to enable the wireless on your Netgear router. This must be set up first, because the DAP1522 is going to connect your TV to the internet, via your Netgear, wirelessly. (assuming I understand what your plan is) (assuming your TV does not have wifi). I don't have a Netgear, so I'm not sure about the steps to take. But in general you need to set up the SSID(name). (for now we'll ignore WEP or WPA encryption).
Then you would log into the DAP1522 to configure it to use the same SSID. It can be an automatic or manual setup, but a login is required to run the setup. You should take the ethernet cable that connects your PC to the Netgear router, unplug it from the Netgear, plug it into the Dlink DAP1522, run your web browser (internet explorer, or firefox), and type in the address 192.168.0.50 (that's the DAP1522). Click on login. Click on Setup near the top of the window, toward the left, click on Wizard all the way to the left. Click on Launch Setup Wizard. Type in the SSID to connect.
Those are the basic steps, but I'm sure there will be more questions.
