Most modern Wi-Fi routers allow owners to specify passwords for their Wi-Fi network in the router's Web-based configuration utility, often accessed in a Web browser at the address 192.168.1.1. After logging into the utility, users can enter a password for the network and change its encryption settings.
While home Wi-Fi routers often default to an IP address of 192.168.1.1, this address may be different on some models and networks. In this case, it is necessary to use the actual address of the router to log into its configuration utility. Logging in requires an administrator password for the router. For maximum security, it is best to specify a different Wi-Fi network password from the router's administrator password, as if the passwords are the same, then anyone with Wi-Fi access to the router can alter its settings if they wish.
When specifying a Wi-Fi password for a network, it is also important to select the correct encryption scheme to maximize its security. In particular, the older Wired Equivalent Privacy scheme was used for early Wi-Fi networks and has been compromised by hackers for several years. WEP encryption should never be used in place of the more secure Wi-Fi Protected Access protocol unless it is necessary for compatibility with older devices.
