. WPA2 provides a secure connection but some older
WiFi devices do not detect WPA2 and support only WP

network includes such older devices, select WPA [TKIP] + WPA2 [AES]
security.
• WPA [TKIP] +WPA2 [AES]. This type of security enables WiFi devices
that support either WP
A or WPA2 to join the modem router’s WiFi
network.

9. Make sure that you can reconnect over WiFi to the network with its new security settings.
If you cannot connect over WiFi, check the following:
• If your computer or WiFi device is already connected to another WiFi network in your
area, disconnect it from that WiFi network and connect it to the WiFi network that the
modem router provides. Some WiFi devices automatically connect to the first open
network without WiFi security that they discover.
• If your computer or WiFi device is trying to connect to your network with its old
settings (before you changed the settings), update the WiFi network selection in your
computer or WiFi device to match the current settings for your network.
