3.2 View/Modify Configuration
If you would like to view or modify Emerald USB Antenna wireless parameters (i.e. to
connect to another network or type of network) proceed as follows:
1. Right-click on the Client Manager icon on the Windows taskbar.
2. From the menu, select Configuration Profile and select:
§ Add/Edit Profile to add a new profile or to modify an existing profile.
§ One of the existing profiles (if present) to select a profile without viewing or
modifying the settings.
After selecting and another profile, the Emerald USB Antenna will use the selected
profile to connect to the wireless network.
3.3 Advanced Configurations
Although your Emerald USB Antenna will work fine in most network environments with
the basic settings described earlier in this manual, you may wish to explore the
advanced parameters options as displayed on the Client Manager’s Add/Edit
Configuration window.
Advanced parameters can only be specified if the Emerald USB Antenna is connected
to an existing network. Consult your LAN Administrator for information about whether
these parameters apply to your situation.
Encryption Tab
The Encryption tab enables you to define the encryption keys that your Emerald USB
Antenna client station should use to encrypt and decrypt data that will be transmitted via
the wireless interface. You can identify up to 4 different key values, but you can only
activate one at a time.
The length of the key you can use depends on whether devices in your wireless network
you support WEP 64 or WEP 128. YDI Diamond products use WEP 64, and YDI
Emerald products support WEP 128.
Devices that support WEP 128 (like the Emerald USB Antenna) can also support WEP
64. However, WEP 64 devices will not support WEP 128. Therefore, if you use
encryption in a network with both types of devices, you must use WEP 64.
Note: Check the documentation that came with any other devices in your network to
find out which kind of encryption, if any, they support.
Keys can be entered in Hexadecimal or Alphanumerical format. Whichever format you
choose, the key that you enter is used in an encryption algorithm to encode the data
that you send. Only another wireless card using the same key can decode and receive
the data.
WEP 64 requires a 5-character Alphanumeric Text key or a 10-character Hexadecimal
key. WEP 128 requires a 13-character Text key or a 26-character Hex key. Hex keys
