CHAPTER 2: OPEN OR WEP-ENABLED NETWORKS 7

STEP 1: TURN ON WI-FI RADIO

the right side of the SoMo 650.

Alternatively, you can tap on the Wi-Fi and

Bluetooth status line in the Today screen.

Wi-Fi button to indicate that the Wi-Fi radio is

off. Tap on the button to turn on the radio. The

“x” will disappear.

3. The Wi-Fi status icon will appear at the top of

the screen. The icon varies based on your

To connect to a WLAN with a profile, tap and hold

your stylus on the WLAN in the list. In the pop-up

menu, tap Connect.

•Network name: Enter the SSID if it isn’t already

provided. The SSID is case-sensitive.

•Connects to: Select either The Internet or Work. In

most cases, you should select The Internet.
