Hi,
Unless you changed something in the setup, there is a little sticker on the side of the router that has the default settings to connect to the wifi bands, ie, the 2.4GHz and 5GHz, they are normally enabled by default. If you are new as your post indicates, you really need to making sure the encription is also enabled. You should be able to use the "Wizard" to help you set things up, again assuming you have not already changed the settings. Try to do as much reading as possible and just spend some time going through all the tabs in the GUI for the router, enter 192.168.0.1 into your browser and hit enter. If no changes have been done leave the password blank and hit enter. That should get you going. Good luck
