TROUBLESHOOTING – No Service/Network Failure
Symptom: When I attempt to make a call, the phone displays "Network
Failure."
Corrective Action:
• You may have left the range of your wireless access point. Move closer
to the access point to regain the signal.
• Verify your broadband connection is functioning properly by attempting
to connect to a website from a PC on the same access point.
