Changing the Wifi password becomes important when a user wants to secure the myrouter.local network from unauthorised access. Users are being recommended to change the default password used during the setup process to connect to the Linksys router. You need to make sure that the Wifi password you set is different from the login password as both the passwords play a different role in a router. A Wifi password secures the network of a router whereas the login password secures the management and monitoring of a device.
