Wireless Connectivity

If you are having trouble connecting wirelessly to the modem router, try to isolate the
problem:
• The computer or WiFi device that you are using does not find the WiFi network.
This can happen for the following reasons:
- Someone pressed the WiFi On/Off button on the modem router, which turned off the
wireless radios.
Check the 2.4 GHz and 5 GHz LEDs on the front of the modem router. If they are off,
press the WiFi On/Off button to turn the wireless radios back on.
- Someone logged in to the modem router and disabled its wireless radios or set up a
wireless schedule.
In this case, pressing the WiFi On/Off button does not turn the wireless radios back
on. You must log in to enable the wireless radios. Use an Ethernet cable to for a wired
connection to the modem router. Then log in and change the settings. For more
information, see Control the Wireless Radios on page 54.
- Someone logged in to the modem router and disabled its SSID broadcast. Your
wireless network is hidden and does not display in your wireless client's scanning list.
(By default, SSID broadcast is enabled.)
To connect with WiFi, you must type the network SSID and password. For information
about how to enable the SSID broadcast, see Specify Basic WiFi Settings on
page 49.
• You can find the WiFi network, but you can't connect. Check the following:
- Make sure that your computer or WiFi device supports the security that you are using
for your wireless network (WPA or WPA2)?
- You are not sure what the WiFi password is.
The preset WiFi password is on the product label. If you changed it and do not
remember the new password, you can use a wired Ethernet connection to log in to
