If router is brand new you should have a set up disk. the set up disk will walk you through it or you might log onto Belkin site to see a walk through set up. If you can access internet from modem to router to internet. That means router is functioning properly. To go completely wireless you will need to secure your network and setup your access codes. Definitely use the setup disk to do this. A unsecured wireless network is a nightmare waiting to happen. Good luck
