• If you have connected to a secure network before, the phone
remembers the settings unless you sign out or the phone is
reset. You can view and manage your Preferred Networks as
described in "Networks in Range Options" on page 28.
Wireless Range and Interference
Wireless networks have one or more access points or routers that
send out wireless signals. The distance that the signal travels is
the wireless range. Interference can block a wireless signal.
The strength and range of the wireless signal depend on the
equipment used. As you move the WiFi phone away from an
access point or router, you could lose your wireless connection.
The following can cause interference and prevent you from
connecting to a wireless network:
• Large metal surfaces
• Microwave ovens
• 2.4-GHz cordless phones
• Aquariums or large fish tanks
• Walls built with concrete or metal
