Chapter 2: Using the Adapter’s Configuration Utility The section is useful in reviewing the networks that are currently available for you to connect to with the adapter, as well as viewing basic information about the networks. This information includes the following: ESSID - The name of the network. The name will be blank if the wireless router or access point is configured not to broadcast it. MAC (ESSID) - The MAC address of the wireless router or access point.
AT-WCU201G Wireless Adapter Card Installation Guide In order for the wireless adapter to access one of the networks listed in Available WANs, you have to configure it with the network’s name and the appropriate security information. This is referred to as creating a Preferred WLAN profile. After you have created a profile, the wireless adapter can connect to the specified network whenever it detects a wireless router or access point that is a part of the network.
Chapter 2: Using the Adapter’s Configuration Utility Creating a Preferred WLAN Profile The following procedure explains how to create a Preferred WLAN profile for the following wireless network environments: No security WEP security WPA-PSK and WPA2-PSK security Note The AT-WCU201G wireless adapter also supports Ad Hoc, WPA/ WPA2 Enterprise, and 802.1x authentication, but these topics are beyond the scope of this manual. To create a Preferred WLAN, perform the following procedure: 1.
AT-WCU201G Wireless Adapter Card Installation Guide The Wireless Network Properties window is shown in Figure 26. Figure 26. Wireless Network Properties Window Depending on how you opened the window, some of the information may already be filled in for you. 4.
Chapter 2: Using the Adapter’s Configuration Utility No Security A Preferred WLAN without security is appropriate in a wireless network environment where there is no encryption or authentication between the wireless nodes and the wireless routers or access points. Caution A wireless network without security is vulnerable to unauthorized access. To configure the Wireless Network Properties window for a Preferred WLAN with no security, perform the following procedure: 1.
AT-WCU201G Wireless Adapter Card Installation Guide In a Shared Key environment a node must authenticate itself to the access point using a shared WEP key that is present on both the node and the access point. Only after a node is successful authenticated will the access point allow it access to the network. This setting must be the same on both the wireless adapter and the wireless router or access point. 3. Click the Data Encryption parameter and from the pull-down menu select WEP.
Chapter 2: Using the Adapter’s Configuration Utility The key lengths for an ASCII key are as follows: – A key length of 64 bits requires 5 ASCII characters. – A key length of 128 bits requires 13 ASCII characters. – A key length of 152 bits requires 16 ASCII characters. The wireless client and access point can use different keys to encode the network traffic that they each send.
AT-WCU201G Wireless Adapter Card Installation Guide 3. Click Data Encryption and select either TKIP (Temporal Key Integrity Protocol) or AES (Advanced Encryption Standard) from the pull-down menu. The encryption method must be the same on both the wireless node and the wireless access point. 4. Click the Authentication Config button. The Advance Security Settings window is shown in Figure 27. Figure 27. Advance Security Settings Window 5.
Chapter 2: Using the Adapter’s Configuration Utility 7. Click OK to close the Wireless Network Properties window. The Preferred WLANs section of the Configuration tab should now include a new Preferred WLAN profile for a wireless network using WPA-PSK or WPA2-PSK security. 8. In the main window of the configuration utility, click Apply. This completes the procedure for creating a Preferred WLAN profile with WPA/WPA-PSK security.
AT-WCU201G Wireless Adapter Card Installation Guide Configuring the IP Address To configure the IP address for a Preferred WLAN profile or to activate the DHCP client, perform the following procedure: 1. Start the configuration program by clicking the program’s icon, shown in Figure 23 on page 35, located in the toolbar on the desktop. The main window of the configuration utility is shown in Figure 24 on page 35. Note Perform step 2 if you created profile groups, which are optional.
Chapter 2: Using the Adapter’s Configuration Utility The LAN Settings window is shown in Figure 28. Figure 28. LAN Settings Window 7. If you want the adapter to obtain its IP address, subnet mask, and default gateway from a DHCP server on your network, click Obtain an IP address automatically. A check in the dialog box activates the DHCP client. 8. If you want to manually enter an IP address, do the following: a. Click Obtain an IP address automatically to remove the check from the dialog box. b.
AT-WCU201G Wireless Adapter Card Installation Guide DNS server addresses and enter the IP address in the field. You can enter up to two IP addresses of domain name servers.

Click OK to close the Wireless Network Properties window. 12. Click the Option tab. 13.
Chapter 2: Using the Adapter’s Configuration Utility Deleting a Preferred WLAN Profile To delete a Preferred WLAN profile, perform the following procedure: 1. Start the configuration program by clicking the program’s icon, shown in Figure 23 on page 35, located in the toolbar on the desktop. The main window of the configuration utility is shown in Figure 24 on page 35. Note Perform step 2 if you created profile groups, which are optional.
AT-WCU201G Wireless Adapter Card Installation Guide Importing and Exporting Preferred WLAN Profiles You can export a Preferred WLAN profile into a separate file and then import the file onto another computer. This can simplify the task of configuring a large number of AT-WCU201G adapters that are to have similar or identical Preferred WLAN profiles.
Chapter 2: Using the Adapter’s Configuration Utility The Save As window is displayed for saving the profile file. 7. Specify the location where you want to store the profile and a filename. The filename extension must be “.AWP”. 8. Click OK. The profile is saved as a separate file on your computer. This completes the procedure for exporting a Preferred WLAN profile.
AT-WCU201G Wireless Adapter Card Installation Guide The profile is incorporated as a Preferred WLAN into the configuration utility. The wireless adapter will establish a connection if it is within range of a wireless router or access point of the network defined by the profile.
Chapter 2: Using the Adapter’s Configuration Utility Working with Profile Groups Profile groups allow you to organize your Preferred WLAN profiles. You can place the profiles in different groups to make them easier to find and manage. Creating profile groups is optional. There can be only one active profile group at a time. The wireless adapter uses the profiles in the active group to establish a connection to a wireless network. The profiles in the other groups are inactive.
AT-WCU201G Wireless Adapter Card Installation Guide 5. You can now add profiles to the new group by either creating them or, if they already exist, moving them from an existing group to the new group. For directions, refer to “Creating a Preferred WLAN Profile” on page 38 and “Moving a Preferred WLAN Profile” on page 53. Moving a Preferred WLAN Profile To move a profile to a different group, perform the following procedure: 1.
Chapter 2: Using the Adapter’s Configuration Utility 3. Click Rename. The Group Rename window is shown in Figure 33. Figure 33. Group Rename Window 4. Enter the new name for the group and click OK. The name can be up to 15 alphanumeric characters. Spaces are allowed. Deleting a Group This procedure explains how to delete a profile group. Caution Deleting a profile group deletes all the Preferred WLAN profiles in the group.
AT-WCU201G Wireless Adapter Card Installation Guide Selecting the Active Profile Group This procedure selects the active profile group for an adapter. The switch uses the profiles in the active group to establish a connection to a wireless network. There can be only one active group at a time for a wireless adapter. The active group is designated with the icon in Figure 31 on page 52. To select the active profile group, perform the following procedure: 1.
