Connection to the Wireless network established
Configuration procedure: The configuration procedure for the client workstation is relatively simple: 1. Initial search for an Access Point (“Infrastructure” mode) or for client stations present on the network (“Ad-Hoc” mode), 2. Configuration of the Wireless connection. 3. Association and authentication with the Access Point or the chosen client workstation.
The operating modes The 802.11 standard defines two operating modes for the Bewan Wi-Fi USB 54 adapter. The mode to be selected depends on the wireless network’s configuration type: •
Infrastructure mode, in which the client workstations equipped with the Bewan Wi-Fi USB 54 are connected to an Access Point. This is the default mode at the time of the adapter’s installation.
•
Ad-Hoc mode, to connect directly to another Wireless workstation without an Access Point.
Bewan Wi-Fi USB 54
15
Infrastructure mode In this mode, the wireless network consists of at least one Access Point (also called a hub), connected to the infrastructure of the wired network and a series of wireless network workstations (the client workstations). These workstations (desktop or laptop PCs), fitted with a USB adapter and possibly also with Wireless cards, are connected to the Access Point that serves as the bridge between the wired network and the wireless client workstations.
Thanks to a much broader operating perimeter, the Access Point will allow you to extend the range of communications and to authorise the connection of a much greater number of users. Given that the Access Point is fixed, the network’s radius is easy to identify. In case of mobile users, the workstations can easily be moved around within the cell that corresponds with the area covered by the Access Point. Through the Access Point, the wireless users will be able to communicate with one another and with the wired network.

Configuration Once the utility has been launched, proceed as follow: 1. Click on the AP List tab. This tab lists all of the other available Wireless devices to which you can connect, as well as their characteristics (MAC address, Signal strength, Channel used, usage or not of Encryption WEP, operating mode). If an Access Point is already configured, it should now be detected and made available. Note: click on the Refresh button to update the information displayed. 2. According to the Network Name, click on the identification value for the Access Point to which you wish to connect, then click on the Connect button (or double-click on the Network Name).
3. When a circle appears in the Access Point icon, this means that your wireless connection is established with the remote Access Point.
Note: your adapter connects to the Access Point on the communication channel it has set. Likewise, the transfer rate used corresponds to that indicated by the Access Point.

4. To obtain information about the Access Point in question, click on the Link Information tab. The following screen appears.
5. Click on the More… button. The window will display the current connection parameters (network name, operating mode, channel used, encryption activated or not, rate of transmission).
Bewan Wi-Fi USB 54
18
Ad-Hoc mode In this mode, the client workstations (at least two) communicate directly with one another, with no Access Point or connection to a wired network. This mode provides for quick and simple creation of a wireless network in locations where there is no wired infrastructure or when access to the wired network is forbidden. This is referred to as a peer-to-peer architecture.
The connection’s speed will depend on the distance between the various stations and on the type of building in which the network is installed. Given the absence of relays (as the network does not require an Access Point), the operating perimeter is smaller. This operating mode is more suited to short distances, and for when the users are not moving around during the transmission. Required configuration: When two machines are in the same perimeter, they must recognize each other in order to exchange data. The parameters must therefore be the same on all workstations if the wireless network is to operate. All of the workstations must: •
be configured in “Ad-Hoc” mode,
•
use the same network name (SSID parameter),
•
select the same communication channel,
•
enter the same encryption key, if they want to use the WEP Encryption in order to secure the Wireless network.
Note: in this mode, no DHCP server is available. Each workstation on the wireless network must therefore be assigned a static IP address within the same addressing plan. To configure your computer, refer to the chapter “Configuration of the computers” on page 24.

Configuration Once the utility has been launched, proceed as follow: 1. Click on the Profile Setting tab, then on the Add button. 2. In the Profile Name section, enter the name of your new profile. Click on Next.
3. In the Network Name section, enter the identification value for the network to which you wish to connect. Note: you must respect case (capitals/lower case). 4. In the Network Type section, select the Peer to Peer operating mode (synonym of Ad-Hoc). 5. In the Transfer Rate section, select the transfer rate. Check that the rate chosen corresponds to that configured on the remote Wireless station. 6. In the Channel section, select the channel chosen for communication with the remote Wireless equipment. Then click on Next.

Note: if you wish to connect to one or more client workstation(s), the selected frequency must be the same on all of the devices connected to the wireless network in order for the connection to operate. 7. You can now decide whether or not to activate WEP encryption on your adapter. If you activate WEP encryption, refer to the section “WEP encryption” on page 21. 8. In the IP Setting section, select Enable, then click on Next. 9. In the DHCP Status section, select Disable in order to allocate a fixed IP address to your Wireless station. 10. In the IP Address and Subnet Mask sections, enter the IP address you wish to attribute to your adapter and the corresponding subnet mask. 11. Click on the Complete button to validate the parameters in your profile. 12. Once your profile is created, the driver seeks an existing Ad-Hoc network using the same SSID (Network Name) to establish the connection. Note: if the remote Wireless device is already configured, it should be detected and available in the AP List tab. You just need to double-click on the name (Network Name field) of the corresponding hardware to establish the Wireless connection.

Configuring encryption One of the major aspects of the wireless network is its security. For obvious reasons, wireless connections are easy to intercept. Data encryption helps to ensure the security of data transmissions.
WEP encryption With WEP (Wired Equivalent Privacy), a user identification mechanism, you can ensure the security of data transmission between the client station and an Access Point (or router) or other client stations, using an encryption key. Without encryption, anyone within the network coverage zone can intercept and decode frames sent to other parties. The aim of WEP encryption is to provide confidentiality of data, equivalent, if not superior, to wired networks, and thus optimise reliability in the transmission of data packets. To configure and activate WEP, you should proceed as follows: 1. In the Authentication Mode section, select the configuration options in order to verify the identity and access privileges of mobile network cards. This consists of validating a user or system, prior to communication. It is possible to choose between Open System or Shared Key. •
Open System: Open system identification is the simplest identification algorithm available. It is an algorithm which requires no identification. Any station requesting identification with this algorithm will be accepted if the type of identification on the receiver station is set to receive open system identification. This identification allows any wireless devices to communicate with each other.
•
Shared Key: Shared Key identification uses the WEP network key to identify the remote Wireless device. If the remote device uses an incorrect key, or no key, the user is denied access. Shared Key identification prevents unauthorised devices from connecting to your equipment.
2. Click on Next.

3. In the Encryption section, select the level of encryption (corresponding to the length of the key): 64 bits or 128 bits. We recommend you use the highest level of encryption.
Then click on Next. 4. In the Input Method section, select the input method: Alphanumeric, Hexadecimal or Passphrase format.
•
If you select Alphanumeric mode, you should use characters between "a-z", "A-Z" and "09".
•
If you select Hexadecimal mode, you should use characters between "a-f", "A-F" and "0-9".
•
If you select Passphrase, you ask the computer to generate encryption keys automatically. Select a word or phrase (e.g. "bewan") in the Key section. The keys are generated automatically. This notably facilitates the key setting and memorisation process.
Bewan Wi-Fi USB 54

5. In the Key section, enter your key. Use of WEP keys: •
64 bit WEP key: enter 5 alphanumeric characters or 10 hexadecimal characters.
•
128 bit WEP key: enter 13 alphanumeric characters or 26 hexadecimal characters.
For example, a 64 bit WEP key in Alphanumeric mode or Hexadecimal mode could have this type of format: •
Alphanumeric: MaCle
•
Hexadecimal: 11AA22BB33
6. In the Key Index section, select the key to be used. There are 4 keys, but only one may be used. Reminder: WEP uses a secret key. For the Bewan Wi-Fi USB 54 adapter to be able to dialogue with a client station (Ad-Hoc mode) or an Access Point (Infrastructure mode), the adapter and the remote equipment must use the same encryption key. It is important to note the result obtained carefully, to be able to configure your other wireless devices. Activate WEP on each of your adapters, cards or Access Points, then enter the key of the Bewan Wi-Fi USB 54 you have entered, and the link will be established between the wireless devices (when WEP encryption was activated on the Bewan Wi-Fi USB 54 adapter, the link was logically interrupted with the other devices).
7. Click on Next. When your profile has been fully created, the encryption is acknowledged. The padlock symbol appears next to your profile name.

WPA encryption In addition to WEP, you can also use WPA encryption with the Bewan Wi-Fi USB 54. Caution: the WPA protocol can only be configured in Infrastructure mode (with an Access Point). To configure WPA using the utility programme provided, you must first update your version of Windows XP. If you have already installed Windows XP Service Pack 2, the Windows XP patch for WPA is included in the update. If not, you will have to download and install the patch, which is available free of charge from the official Microsoft website. Here is a link to the Windows XP (KB826942) patch download page: >> Click here to download the Windows XP patch for WPA WPA (Wi-Fi Protected Access) is a security protocol designed to replace the current WEP (Wired Equivalent Privacy) for Wi-Fi links using static keys, which must be changed manually. WPA uses different data encryption protocols (or algorithms): •
TKIP (Temporal Key Integrity Protocol): instead of using a set key to encode the data packets, it regularly generates new dynamic keys derived from the main key, providing increased security. Note: all existing devices can benefit by simply upgrading the software used.
•
AES (Advanced Encryption Standard): this is a symmetrical algorithm for block encoding. It operates using 128 bit blocks. This block encryption provides a greater level of security. Caution: this requires the use of a dedicated chip. It is therefore not possible to upgrade existing equipment. Its compatibility remains limited to devices fitted with this chip.
Proceed as follows: 1. In the Authentication Mode section, select WPA-PSK. 2. In the Encryption section, select TKIP or AES.
3. Click on Apply.

4. Then enter your key value. The key must comprise a minimum of 8 characters.
5. Click on Next. When your profile has been fully created, the encryption is acknowledged. The padlock symbol appears next to your profile name. Note: you must use the same algorithm (TKIP or AES) as that used for the Access Point. You must also enter the same key so that both pieces of Wireless hardware can communicate.

4. Select the option Obtain an IP address automatically, then click on OK.
Fixed IP address You have chosen to configure the Bewan Wi-Fi USB 54 in order to connect to an Access Point, a router or another Wireless device using a static IP address. You must therefore assign fixed IP addresses to your computer and to any others on the wireless network. Proceed as follows: 1. Click on Start, then point to Settings, and then click on Control panel. Then double-click on the Network and Dial-up Connections icon. 2. With the right mouse button, click on Local Area Connection 2 and select Properties in the menu. 3. Select the element Internet Protocol (TCP/IP), then click on Properties. 4. Select Use the following IP address. 5. In the IP address field, enter the IP address that you have decided to assign to the PC. Important: •
The PC’s IP address must imperatively fall within the same addressing range as the one used by the Access Point or the remote Wireless device.
•
The PC’s IP address must be unique, i.e. different from the ones used by other devices present on the local network (other computers, Access Point, router…).
•
The PC’s IP address must fall into a range reserved for private networks. Indeed, your local network must not use addresses that are reserved for the Internet. This would cause problems when connecting your network to the Internet.
