Configure WPA/WPA2 Enterprise WiFi Security
Remote Authentication Dial In User Service (RADIUS) is an enterprise-level method for centralized Authentication,
Authorization, and Accounting (AAA) management.To provide WPA/WPA2 enterprise WiFi security, the WiFi network
that the modem router provides must be able to access a RADIUS server.
If you want to change the WiFi settings of the modem router’s main network, use a wired connection
to avoid being disconnected when the new WiFi settings take effect.
To configure WPA/WPA2 enterprise security:
1. Launch a web browser from a computer or WiFi device that is connected to the network.
2. Enter http://www.routerlogin.net.
A login window opens.
3. Enter the modem router user name and password.
The user name is admin. The default password is password. The user name and password are case-sensitive.
The BASIC Home page displays.
4. Select Wireless.
The Wireless Settings page displays.
If you are configuring a guest network, select Guest Network instead. The Guest Network
Settings page displays.
