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 hotspots 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.
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 turn Wi-Fi on and connect to a Wi-Fi network just press Menu > Settings > Touch Wireless & networks > Wi-Fi settings. Check Wi-Fi to turn it on. The phone scans for available Wi-Fi networks and displays the names of those it finds. Secured networks are indicated with a Lock icon. If the phone finds a network that you connected to previously, it connects to it.
Touch a network to connect to it. If the network is open, you are prompted to confirm that you want to connect to that network by touching Connect. If the network is secured, you’re prompted to enter a password or other credentials. (Ask your network administrator for details.)
When you’re connected to a network, you can touch its name in the Wi-Fi settings screen for details about the speed, security, address, and related settings.
To receive notifications when open networks are in range just check Network notification on Wi-Fi settings screen. You can uncheck this option to stop receiving notifications.

You can add a Wi-Fi network so the phone will remember it, along with any security credentials, and connect to it automatically when it is in range. You must also add a Wi-Fi network to connect to it, if it does not broadcast its name (SSID), or to add a Wi-Fi network when you are out of range of it.
To join a secured network, you need to contact the network’s administrator to learn what security scheme is deployed on it and to obtain the password or other required security credentials.
