Protect your Netgear wireless network with a password to prevent unauthorized access. Using an unsecured connection is dangerous; attackers can steal sensitive information from you if they can connect to the network. To make the connection even more secure, protect the router itself with a password. All Netgear routers come with a default username and password; anyone can access the device unless you change the password.
Changing the Wireless Password
Open a Web browser and navigate to www.routerlogin.net or www.routerlogin.com to access the Netgear Web interface. Alternatively, use the default IP address of the router: 192.168.1.1 or 192.168.0.1. If you can't access the Web interface, use the Command Prompt utility to find the correct IP address.
Type the username and password into the User Name and Password fields and click OK to log in to the Netgear Web interface.
Select Wireless Settings from the Setup section of the left pane to view all settings related to the WiFi network.
Select one of the security options from the Security Options section and type the password into the Passphrase field. WPA-PSK or WPA2-PSK -- depending on the router model -- is good enough to protect the network against most, if not all, attacks. Click Apply to apply the new password.
Changing the Administrator Password
Change the administrator password for the router to prevent others from logging in to the Web interface and changing the settings.
Select Set Password from the Maintenance section of the left pane after you log in to the Netgear interface and then type the old password and the new password into the relevant fields. Click Apply to change the password.
