3. ”Statistics” screen is used to count the total Rx and Tx data packets, including transmitted, retransmitted and fail to receive ACK after all retries. You can click the “Reset Counter” button to clear the count.

Profile Settings

Except the above common connection type, you can also connect to the wireless network by adding a profile on the “Profile List” screen. The Profile screen is used to save the wireless network parameters. When the adapter is successfully connected to a network, the profile name of this network will automatically be added here, which helps the adapter to quickly connect to the wireless network next time. However, there’s one exception that when you have set the hidden SSID, namely the SSID cannot be scanned, and then you must manually connect by adding the profile name. The main interface is as shown below.

• Add: create a new profile
• Delete : delete the existing profile
• Edit: modify the existing profile

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 different from Ad-Hoc in that in this mode the computer installed with the wireless network adapter has to fulfill the wireless communication via AP or wireless router. It can be divided into two modes: “wireless AP + wireless network 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 Profile 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 profile name and SSID or you can find the SSID you wish to connect from the drop-down list.
   

Click the next button to select the authentication type and encryption type such as WPA－PSK and AES, and then input the key and click next.

After a profile is successfully added, the profile name can be seen on the profile list; you can edit, import or export the profile, click “Active” to finish 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 connect is disabled, then the wireless adapter cannot scan the SSID, thus you need to connect by creating the corresponding profile.

Ad-Hoc Profile management

Using the Ad-hoc mode to establish a wireless network requires that each computer 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.

2. Right click “My Network Places” on your computer’s desktop and selects “Properties”.

3. Right click “Wireless Network Connection”, and select “Properties”

4. Select “Internet Protocol(TCP/IP)”and click “Properties”.

5. Please enter the IP address and subnet mask, and make sure this IP address is not used by other devices in the network. For example: if your wireless adapter’s IP address is 192.168.0.1, then set other wireless adapters’ IP addresses within the range of 192.168.0.2—192.168.0.254.Click “Ok” to save the settings.

6. Create a new Ad-hoc profile
   Click the “Add” button and enter the network name in the SSID field to identify the wireless network, and select Ad-hoc as the network type and then select the channel.

Click the “Next” button to select the authentication type and encryption type and then input the correct key and click “Next”.
After a profile is successfully added, the profile can be seen on the profile list, select it and click the “Active” icon on the lower right corner. And then search for the wireless network on other clients. Double click the wireless network you have configured and you’ll be prompted for the key .After entering the key, click “Connect”.

When the highlighted part shows “Connected”, it indicates the connection is successful.
