Up to 145 Mbps is the default setting, which allows 802.11n and 802.11g WiFi devices to
join the network. g & b supports up to 54 Mbps. The 300-Mbps setting allows 802.11n
devices to connect at this speed.
11. Click the Apply button.
Your settings are saved.
If you used a WiFi network connection and you changed the SSID, you are disconnected
from the network.
12. Make sure that you can use WiFi to connect to the network with its new settings.
If you cannot connect, check the following:
• Is your WiFi-enabled computer or mobile device connected to another WiFi network in
your area? Some WiFi devices automatically connect to the first open network without
WiFi security that they discover.
• Is your WiFi-enabled computer or mobile device trying to connect to your network with
its old settings (before you changed the settings)? If so, update the WiFi network
selection in your WiFi-enabled computer or mobile device to match the current
settings for your network.
Change the WiFi Security Option
Your modem router comes with preset WPA2 or WPA security. The password that you enter to
connect to your network is unique to your modem router and is on the modem router label. We
recommend that you do not disable security.
To change the WPA settings:
1. Launch a web browser from a WiFi-enabled computer or mobile device that is
connected to the network.
2. Type http://routerlogin.net or http://192.168.0.1.
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 WiFi.
The Wireless Settings page displays.
5. Under Security Options, select a radio button for one of the following WPA options:
• WPA2-PSK [AES]
• WPA-PSK [TKIP] + WPA2-PSK [AES]
