Connecting to a wireless network
Connect your tablet to the Internet or other wireless networks so that you can browse on your tablet and
share information.
Your tablet supports the following wireless networks:
• Wi-Fi network
The Wi-Fi feature provides network access at distances of up to 100 meters (328 feet) depending on the
Wi-Fi router and your surroundings. Your tablet is installed with a wireless-local-area-network card
(wireless-LAN card) to support the Wi-Fi connection. The quality of the Wi-Fi signal is affected by the
number of connected devices, the infrastructure, and the objects through which the signal is transmitted.
• Mobile broadband network (supported by some models)
The mobile broadband feature enables you to connect to the Internet from any location where cellular
service is available. Mobile broadband connections use 3G, 4G, or LTE cellular and mobile networks,
just as phones do. Mobile broadband connection is supported only on tablet models that come with
a wireless-wide-area-network card (wireless-WAN card) installed.
A micro Subscriber Identity Module (SIM) card or an external mobile broadband device is required to
connect to a mobile broadband network. For instructions on replacing or installing a micro SIM card, see
“Installing and removing the micro SIM card” on page 31.
Your tablet also supports Bluetooth and NFC wireless communications. For more information, see “Using
the NFC connection” on page 34 and “Using Bluetooth devices” on page 34.
To join a wireless network:
1. Tap the wireless-network icon on the taskbar. A list of available wireless networks is displayed.
