Configuring BeWAN Wi-Fi cards The following chapter describes how to use the utility to configure your card, as well as the advanced functions. This utility allows rapid access to all of the card’s parameters. It allows you to modify or verify information relating to the configuration of your card. After installation of the drivers, an icon appears in the task bar. Double-click on this to open the utility’s main menu. Note: if the icon does not appear, click on Start, go to Programs, Wireless Network, then click on Wireless Utility. Double-click on the icon to launch the utility. The icon’s colour indicates the current status of your connection: Red
No connection to the Wireless network
Blue
Æ
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.
Operating modes Standard 802.11 defines two operating modes for your BeWAN Wi-Fi card. The mode to be selected depends on the type of wireless network configuration: •
Infrastructure mode, in which the client workstations equipped with the BeWAN Wi-Fi cards are connected to an Access Point.
•
Ad-Hoc mode, to connect directly to another Wireless workstation without an Access Point or connection to a wired network.
BeWAN Wi-Fi cards
22
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 (which can itself be connected to Internet) and a series of wireless network workstations (the client workstations). These workstations (desktop or laptop PCs), equipped with BeWAN Wi-Fi 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.
BeWAN Wi-Fi cards
23
Configuration Once the utility has been launched, proceed as follows: 1. Click on the Availiable Networks tab. 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 card 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.

24
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, channel used, encryption activated or not, rate of transmission).
BeWAN Wi-Fi cards
25
Ad-Hoc mode In this mode, the client workstations (maximum five) 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 Encryption WEP 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 “Configuring the computers” on page 31.

Configuration Once the utility has been launched, you should proceed as follows: 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 computer 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.

7. You can now decide whether or not to activate WEP encryption on your card. If you activate WEP encryption, refer to the section “Configuring WEP encryption” on page 28. 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 card 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.

Configuring WEP encryption When you create a profile, one of the main aspects to be taken into account is security. For obvious reasons, wireless links are easy to intercept. 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 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.
2. The Authentication Mode section defines the configuration options for shared wireless networks, 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 and 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.

Click on Next.
3. 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 cards

4. 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
5. 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 card to be able to dialogue with a client station (Ad-Hoc mode) or an Access Point (Infrastructure mode), the card 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 (cards or Access Points). Activate WEP on each of your cards or Access Points, then enter the key of the BeWAN Wi-Fi card you have entered, and the link will be established between the cards (when WEP encryption was activated on the BeWAN Wi-Fi card, the link was logically interrupted with the other cards).
6. Click on Next. When your profile has been fully created, the encryption is acknowledged. The padlock symbol appears next to your profile name.

Configuring the computers To connect the BeWAN Wi-Fi cards to a Wireless network, first check that the card parameters are compatible with the wireless network parameters. The configuration TCP/IP varies, depending on whether or not a DHCP server is present on the wireless network. We will refer here to the configuration of computers running the following operating systems: Windows 98/Me, Windows 2000 and Windows XP.
PC running Windows 98/Me Dynamic IP address You have chosen to configure your BeWAN Wi-Fi card in order to connect to an Access Point or a Wireless router using a DHCP server. The latter dynamically assigns IP addresses to computers 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 icon. 2. In the group The following network components are installed, select TCP/IP -> Wireless Network Adapter, then click on Properties.
BeWAN Wi-Fi cards

3. In the IP Address tab in the TCP/IP Properties window, select the option Obtain an IP address automatically.
4. Click on OK to validate the modifications.
Fixed IP address You have chosen to configure your BeWAN Wi-Fi card 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 icon. 2. In the group The following network components are installed, select TCP/IP -> Wireless Network Adapter, then click on Properties. 3. In the IP address tab in the TCP/IP Properties window, select the option Specify an IP address. 4. 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, Wireless card…).
•
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.
In case of uncertainty regarding these points, check with a network specialist.

5. In the Subnet Mask field, enter the corresponding subnet mask value of the BeWAN Wi-Fi card, i.e. « 255.255.255.0 » in our example.
6. Click on OK to validate the modifications.
Internet Gateway To access a shared Internet connection via the wireless network, you should enter your Internet proxy (router IP address). This applies, irrespective of the type of IP address chosen (static or dynamic). You can also enter the DNS server address. 1. Click on the Gateway tab. 2. In the New gateway field, enter the router’s IP address, then click on Add.
3. Then click on OK in each of the windows and follow the instructions on the screen in order to validate the modifications.
