There are two network types for your option when clicking the “Add” button to add
wireless adapter connection: Infrastructure and Ad-Hoc.
Infrastructure is an application mode that integrates the wired and wireless LAN
architectures. It is dierent from Ad-Hoc in that in this mode the computer installed
with the wireless network adapter has to fulll the wireless communication via AP
or wireless router. It can be devided into two modes:“wireless AP + wireless net-
work adapter” and “wireless router + wireless network adapter”.
Ad-Hoc is a special wireless mobile network application mode. All nodes in the
network are equal.Usually it is used to share resources by connecting the opposing
computer’s wireless adapter.
1. Infrastructure Prole Management
When you are connecting the wireless adapter to an AP or a wireless router, please
select the Infrastructure mode.
Click the “Add”button and select the network type as”
Infrastructure”,and enter the prole name and SSID or you can nd the SSID you
wish to connect from the drop-down list.

le list,you can edit , import or export the prole,click “Active” to nish the
connection,now you can also view the detailed connection status on the “Link
Information”screen.
NOTE: If the SSID broadcast function of the wireless router or AP you wish to con-
nect is disabled, then the wireless adapter can not scan the SSID, thus you
need to connect by creating the corresponding prole.
2. Ad-Hoc Prole management
Using the Ad-hoc mode to establish a wireless network requires that each com-
puter should be equipped with a wireless network adapter. By connecting these
wireless adapters, computers are able to share the resources. The detailed setting
steps are as follows:
1) Firstly you’ll have to allocate a static IP to each wireless adapter to be connected
in Ad-hoc mode.
a. Right click “My Network Places” on your computer’s desktop and select
“Properties”.
