WLAN devices (select models only)
Computers with WLAN devices may support one or more of
three IEEE physical layer industry standards:
■
802.11b, the first popular standard, supports data rates of
up to 11 Mbps and operates at a frequency of 2.4 GHz.
■
802.11g supports data rates of up to 54 Mbps and operates
at a frequency of 2.4 GHz. An 802.11g WLAN device is
backward compatible with 802.11b devices, so they can
operate on the same network.
■
802.11a supports data rates of up to 54 Mbps and operates
at a frequency of 5 GHz.
✎
802.11a is not compatible with 802.11b and 802.11g.
Identifying a WLAN device
As a part of the process for setting up your wireless network, you
will need to identify which integrated WLAN device is installed
on your computer:
1. Select Start > My Computer.
2. Right-click in the My Computer window.
3. Select Properties > Hardware tab > Device Manager >
Network Adapters.
4. Identify the WLAN device from the list that is displayed. The
listing for a WLAN device may include the term wireless,
wireless LAN, WLAN, or 802.11.

If no WLAN device is listed, either your computer does not
have an integrated WLAN device, or the driver for the
WLAN device is not properly installed.
