Now that Plusent routers use TR069 automatic configuration I would expect that you just plug it into the line and it will automatically set itself up for that line.

If you want to configure wireless access etc but don't want to connect to the net just plug it into any computer and don't bother to conenct it to the phone line. Log in from your browser using 192.168.1.254 and the password printed on the label.
PS: Glad to see that wireless networking is now set to WPA as a default.
