Using wireless LAN connections
Your computer comes with a built-in wireless networking card and a configuration utility to help you make
wireless connections and monitor the status of your connection, so that you can stay connected to your
network while you are in the office, in a meeting room, or at home, with no need for a wired connection.
Attention: If you carry your ThinkPad computer with the wireless LAN feature into an airplane, you
need to disable it before boarding. To disable it, refer to the instructions in
wireless
feature.
Note: You can purchase a wireless networking card as an option. For more information, refer to
ThinkPad options.
Tips for using the wireless LAN feature
Place your computer so that there are as few obstacles as possible between the wireless LAN
access point and the computer.
For the best connection of the wireless LAN feature, open your computer display to an angle of
slightly more than 90 degrees.
If you use the wireless feature (the IEEE 802.11 standard) of your computer simultaneously with a
Bluetooth option, data transmission speed can be delayed and the performance of the wireless
feature can be degraded.
