Wireless LAN Modes Using this Device
Ad Hoc Mode
"Ad Hoc Mode" refers to a wireless network architecture where wireless network connectivity between multiple computers is established without a central wireless network device, typically known as Access
Point(s). Connectivity is accomplished using only client devices in a peer-to-peer fashion. That is why Ad
Hoc networks are also known as peer-to-peer networks. Ad Hoc networks are an easy and inexpensive method for establishing network connectivity between multiple computers. Ad Hoc mode requires that the
SSID, network authentication, and encryption key settings are identically configured on all computers in the Ad Hoc network.
Ad Hoc Mode Network
152 - Before Using the Optional Wireless LAN
Access Point (Infrastructure) Mode
Infrastructure mode refers to a wireless network architecture in which devices communicate with wireless or wired network devices by communicating through an Access Point. In infrastructure mode, wireless devices can communicate with each other or with a wired network. Corporate wireless networks operate in infrastructure mode because they require access to the WLAN in order to access services, devices, and computers (e.g., file servers, printers, databases).
Access Point (Infrastructure) Mode Network
ADSL modem, cable modem, or similar
153 - Before Using the Optional Wireless LAN
*An optional hub for a wired
LAN may be required depending upon the type of access point used.
How to Handle This Device
The WLAN device is an optional device that may come pre-installed in your mobile computer. Under normal circumstances, it should not be necessary for you to remove or re-install it. The Operating System that your mobile computer comes with has been pre-configured to support the WLAN device.
