4. Select "Wireless Setup."
5. If given the choice, select "2.4 GHz" or "5 GHz" in the left sidebar. Not all models offer this feature, so don't worry if you do not see this option.

7. Select "Apply" to save changes.
8. Next, make sure the modem is broadcasting the network. To do this, select "SSID Setup."

10. Select "Broadcast SSID" or "Enable SSID."
11. Select "Apply" to save your changes.
The wireless light on your modem will turn green when the WiFi network is enabled. Once it's on, you can connect devices to your wireless network. Be sure to connect devices using the same frequency you selected on your modem (2.4 GHz or 5 GHz).
