Getting started Contents of this manual 1.2 Contents of this manual Table 1-1 gives an overview of the contents of this manual. Table 1-1 Contents of this manual Chapter When to read: This chapter (“Getting started”) Read this chapter on how to implement a Wireless LAN in your (network) environment. Chapter 2: ‘Installing the Access Point’ on page 13 Read this for information on how to install and connect Access Point to your (network) environment.
Getting started Adding Access Points to your (network) environment An Access Point is like a hub. They are mounted at assigned places, each covering its own area in which wireless nodes can operate. The Access Points can be connected to a wired network to communicate with each other and with servers and clients on that network. The 11 Mbps WLAN Access Point can be connected to a 10 or 100 Mbps Ethernet network through an RJ45 (UTP) connector.
Getting started Adding Access Points to your (network) environment When you install a new wireless network, follow these steps: 1. Configure one client. 2. Select the IP settings of this client. 3. Install the Access Point and connect it. 4. Optionally, configure the Access Point from the already configured client using the Web Interface (see chapter 3: ‘Configuring the Access Point’ on page 21). 5. Install other clients if this is applicable to your situation. 1.4.
Getting started Adding Access Points to your (network) environment 2. Optionally, configure the Access Point from an existing computer in the network using Web Interface (see chapter 3: ‘Configuring the Access Point’ on page 21). The IP settings for the Access Point can be retrieved from the network (see also Appendix A: ‘TCP and IP settings’ on page 49. 3. Install the client(s). 1.4.3 Connecting an Access Point directly to a computer You can also add an Access Point directly to your computer.

3 3.1 Configuring the Access Point Introduction The Access Point is a ready to use device. It is delivered with default settings which allow you to have access to it without configuring it. When you do configure the Access Point, you can change the settings with respect to security, radio channels, etc. Whether you need to configure the Access Point or not, depends entirely on how you apply the Access Point to your environment. Section 3.
Configuring the Access Point Starting the Web Interface IP settings can be installed automatically or manually. Table 3-2 3.3 Installing methods for IP settings Install IP settings When Automatically If the Access Point is part of a network with a DHCP server, the DHCP server assigns the IP settings to the Access Point for you. After that you can configure the Access Point by starting a web browser and inserting the IP address of the Access Point on the address bar.

4 4.1 Troubleshooting If KickStart does not find the Access Point you are looking for There are several possible causes depending on the way the Access Point is connected to the network. 4.1.1 Problems on the wireless side Always check the status of the LEDs to see whether you have: • electricity problems, • radio signal problems, or • networking problems. Table 4-1 Troubleshooting the wireless connection of an Access Point Possible cause Solution Is the Access Point powered up. Check the power LED.
Troubleshooting If KickStart does not find the Access Point you are looking for Table 4-1 Troubleshooting the wireless connection of an Access Point (vervolg) Possible cause Solution Is there a network connection? Check the network LED. The Access Point may take up to a minute to find an IP address it can use if Auto IP is used to assign an IP address. Client cannot make connection A wireless client is not (yet) connected to the Access Point.

A A.1 TCP and IP settings Introduction Before installing a wireless network device you must analyze your the network environment. The information in this appendix is only helpful in determining which information is needed for a proper installation of such a device. This appendix explains how devices in a network are identified in order to communicate with each other.
TCP and IP settings How do computers communicate in a network A.2.1 IP address An IP address consists of two parts. The table below describes these two parts. Table A-2 Sections of the IP address Part Identifies Description First part subnet (local network) to which the computer is attached This part of the address is also known as the ‘network portion’; it is similar to the area code of a telephone number.
TCP and IP settings How do computers communicate in a network IP address: 11000000.10101000.11001001.10101101 subnet mask: 11111111.11111111.11111111.11100000 The subnet mask shows that the first 27 bits are the network portion of the address, the last 5 bits are the node portion, which means there is room for 32 addresses on this network (all numbers between 00000 and 11111 in binary). A.2.3 IP address range All addresses in this network share the first 27 bits.
TCP and IP settings IP configuration In order to do this, the sender needs to have the IP address of the gateway for his subnet. Normally, the lowest available node number in the subnet (the network address plus one) is used as the gateway address. A.2.6 MAC address Every Ethernet device has a unique address that is permanently linked to that device. It cannot be changed. On every wireless device, the MAC address is printed on its type label. The MAC address consists of six groups of two digits each (e.g.
TCP and IP settings IP configuration Every host that joins the network will look for a unique node number in the subnet 169.254.___.___ (i.e. network address is 169.254.0.0, Subnet mask is 255.255.000.000). The host will do this by randomly choosing a node number and then checking to make sure no other host is using that IP address. If the IP address is already in use, the host will try again with another random IP number.

B B.1 Wireless LAN Introduction This Appendix explains some of the basic terms and concepts of Wireless LANs. See the specifications of your device for details on the performance of your device Table B-1 Contents of Appendix B. Wireless LAN’s B.2 Section Description B.2 This section explains the basic features of a Wireless LAN. B.3 This section explains the bsic features of an Access Point. B.4 Wireless LAN’s require an extra identification: the Service Set Identification. B.
Wireless LAN The Access Point B.3 The Access Point An Access Point is similar to a hub. It connects computers to each other and to a network. It functions as a node in a network. Only the Access Points on a Wireless LAN require cabling. An Access Point in itself cannot give access to the Internet because data exchange with the Internet needs to be routed through a gateway. Whether an Access Points also gives access to the Internet depends on its firmware.
Wireless LAN Security • the range of the device, • proper propagation of the signal ((conducting) obstacles,), • interference of other devices • number of users. Some devices can handle more than one data rate; see the specifications of your device. B.5.3 Regulatory Domain Every region or country has an institution/agency that governs radio transmissions. Such a region is called a regulatory domain. A wireless LAN uses a spectrum of radio frequencies for which no enduser license is needed.
Wireless LAN Security B.6.1 IEEE authentication This method provides an encryption technique that makes it very difficult to have unauthorized access to the network. Other authentication methods may have been delivered for different types of Wireless LAN devices. B.6.2 Open Systems method This is an IEEE authentication method that does not require password protection. B.6.3 WEP method The IEEE 802.11 standard includes a shared key data privacy mechanism, called 'Wired Equivalent Privacy'.
