How to configure the Apple - A1521 router

The way your router should be configured depends on what brand’s router you have. If you have the router manual then you can take the help from that but if you have not then you should download it from the site of your brand. The most common thing that should be changed while configuring the router is changing the router default password. So you should also do it.
