perform the following procedures to disable your native Windows XP wireless support (Wireless
Zero Configuration Service)
1. Double click the icon on your desktop to start the utility.
2. Make sure that the “Windows Zero Config” checkbox is unchecked.
Ad-Hoc Mode
An Ad-Hoc mode wireless network connects two computers directly without the use of a router or
AP. It is also know as a peer-to-peer network. For example, we can install this wireless adapter
to two computers respectively. The communication between the two computers is an Ad-Hoc mode
network.
13

4. Click OK to add this network into the profile list.
Note: This example is an open wireless network. If you are going to connect to a Wireless adapter
with security protection, you will have to configure the encryption settings in this profile to be
corresponding to the other wireless adapter. Please click on the “Network Authentication” drop
list to select an authentication method, and then select a “Data encryption” type. Fill in each
14
required blanks and click “OK”.
