buttons, though, you should locate the SecureEasySetup button on the device you’re connecting the Adapter to,

such as a wireless router or access point.

4. Starting from the

Available Wireless Network screen, click the SecureEasySetup button on the right hand

side.

5. You will be asked to locate the SecureEasySetup button on the device with which the Adapter will be

communicating. If you are not sure where to find this button, click Where can I find the button?.

This will walk you through a couple of screens to help you find the button, which is usually located on the

front of the wireless router or access point.

If you’ve clicked the button by accident or do not wish to use SecureEasySetup, you can click Cancel to return

to the previous screen.
