Does your wireless device support the security that you are using for your wireless 
network (WPA or WPA2)?

If you want to view the wireless settings for the wireless modem router, use an Ethernet 
cable to connect a computer to a LAN port on the wireless modem router. Then log in to 
the wireless modem router and select Setup > Wireless Settings see (

on page 34). 

Be sure to click Apply if you made changes.

Wireless Signal Strength

If your wireless device finds your network, but the signal strength is weak, check these 
conditions:

Is your wireless modem router too far from your computer, or too close? Place your 
computer near the wireless modem router, but at least 6 feet away, and see whether the 
signal strength improves.

Is your wireless signal blocked by objects between the wireless modem router and your 
computer?

Restore the Factory Settings and Password

This section explains how to restore the factory settings, changing the wireless modem 
router’s administration password back to password. You can erase the current configuration 
and restore factory defaults in two ways:

Use the Erase function of the wireless modem router (see 

Use the Restore Factory Settings button on the back of the wireless modem router. See 

on page 149. If you restore the factory settings and the wireless modem 

router fails to restart, or the green Power LED continues to blink, the unit might be 
defective. If the error persists, you might have a hardware problem and should contact 
technical support at 

Troubleshoot Your Network Using the Ping Utility

Most network devices and routers contain a ping utility that sends an echo request packet to 
the designated device. The device then responds with an echo reply. You can easily 
troubleshoot a network by using the ping utility in your computer or workstation.
