How can you setup a router with your phone?

Download the appropriate app and follow the on-screen instructions. After the app is loaded, it will ask you to connect to the network that's being broadcast out of it. A lot of times, the routers have their own name and network password—it's already set up, so you just follow the instructions that the app gives you. At that point, as soon as you're logged in with that unit, it automatically detects the unit and sets up all the protocols for the type of internet you're using, and it'll ask if you want to change your broadcast ID and password. You should now be online and ready to go!
