How to Access and Change Your Wi-Fi Router's SettingsYour router stores the settings for your home Wi-Fi network. If you want to change something on your network, you have to log in to your router's software, also known as firmware. From there, you can rename your network, modify the password, adjust the security level, and set up or alter a variety of other options.But before you can do all that, you first need to gain access to your router. The process for logging in to your router should be the same whether you use your internet provider's router or you purchased your own router. It should also be the same whether you use a dedicated router or a combination modem/router supplied by your provider.
