Connecting to Wi-Fi networks
Wi-Fi is a wireless networking technology that can provide Internet access at
distances of up to 100 meters, depending on the Wi-Fi router and your surroundings.
To use Wi-Fi on your phone, you access a wireless access point, or “hotspot.” Some
access points are open and you can simply connect to them. Others are hidden or
implement other security features, so you must configure your phone so it can
connect to them.
There are numerous systems for securing Wi-Fi connections, including some that rely
on secure certificates or other schemes to ensure that only authorized users can
connect. For information about installing secure certificates, see “Working with secure
certificates” on page 78.
Turn off Wi-Fi when you’re not using it, to extend the life of your battery.
The Status bar displays icons that indicate Wi-Fi status.
When you connect to a Wi-Fi network, the phone obtains a network address and other
information it needs from the network, using the DHCP protocol. To configure the
phone with a fixed IP address and other advanced settings, press Menu and touch
Advanced. See “Advanced Wi-Fi settings screen” on page 310.
