Introduction August 2003 2-7 Chapter 3 Basic Installation and Configuration This chapter describes how to set up your ME103 802.11b ProSafe Wireless Access Point for wireless connectivity to your LAN. This basic configuration will enable computers with 802.11b or 802.11g wireless adapters to do such things as connect to the Internet, or access printers and files on your LAN. Note: Indoors, computers can connect over 802.11b wireless networks at ranges of several hundred feet or more. This distance can allow for others outside your area to access your network. It is important to take appropriate steps to secure your network from unauthorized access. The ME103 Access Point provides highly effective security features which are covered in detail in Chapter 3, "Configuring Your Wireless Network. Deploy the security features appropriate to your needs. You need to prepare these three things before you can establish a connection through your wireless access point: · · · A location for the ME103 that conforms to the Observing Placement and Range Guidelines below. The wireless access point connected to your LAN through a device such as a hub, switch, router, or Cable/DSL gateway. One or more computers with properly configured 802.11b or 802.11g wireless adapters. Observing Placement and Range Guidelines The operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless access point. The latency, data throughput performance, and notebook power consumption of wireless adapters also vary depending on your configuration choices. Basic Installation and Configuration August 2003 3-1 Reference Manual for the ME103 802.11b ProSafe Wireless Access Point Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the ME103. For complete performance specifications, see Appendix A, "Specifications". For best results, place your wireless access point: · · · · · Near the center of the area in which your PCs will operate. In an elevated location such as a high shelf where the wirelessly connected PCs have line-of-sight access (even if through walls). Away from sources of interference, such as PCs, microwaves, and 2.4 GHz cordless phones. Away from large metal surfaces. If using multiple access points, it is better if adjacent access points use different radio frequency Channels to reduce interference. The recommended Channel spacing between adjacent access points is 5 Channels (for example, use Channels 1 and 6, or 6 and 11). The time it takes to establish a wireless connection can vary depending on both your security settings and placement. WEP connections can take slightly longer to establish. Also, WEP encryption can consume more battery power on a notebook PC. Cabling Requirements The ME103 Access Point connects to your LAN via twisted-pair Category 5 Ethernet cable with RJ-45 connectors. Note: The power adapter and cord shipped with the ME103 limits the distance from an AC outlet. To overcome this, consider using NETGEAR's POE101 Power Over Ethernet Adapter with a Cat 5 Ethernet cable like the one included with your ME103. This adapter sends DC power through an Ethernet cable to enable you to power an access point in a remote location up to 328 feet away. Basic Installation and Configuration August 2003 3-2 Reference Manual for the ME103 802.11b ProSafe Wireless Access Point Default Factory Settings When you first receive your ME103, the default factory settings will be set as shown below. You can restore these defaults with the Factory Default Restore switch on the rear panel -- see "ME103 Wireless Access Point Rear Panel" on page 2-7.

For this reason, use the security features of your wireless equipment. The ME103 Access Point provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs. ME103 ProSafeWireless Access Point LAN Wireless LAN Wireless Data Security Options Range: Up to 500 Feet MODEL 802.11b PWR ME103 1) Open System: Easy but no security 2) MAC Access List: No data security 3) WEP: Security but some vulnerabilities 4) 802.1x: Secure Figure 3-1: ME103 wireless data security options There are several ways you can enhance the security of your wireless network: · Restrict Access Based on MAC address. You can restrict access to only trusted PCs so that unknown PCs cannot wirelessly connect to the ME103. MAC address filtering adds an obstacle against unwanted access to your network, but the data broadcast over the wireless link is fully exposed. Turn Off the Broadcast of the Wireless Network Name (SSID). If you disable broadcast of the SSID, only devices that have the correct SSID can connect. This nullifies the wireless network `discovery' feature of some products such as Windows XP, but the data is still fully exposed to a determined snoop using specialized test equipment like wireless sniffers. Use WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared Key authentication and WEP data encryption will block all but the most determined eavesdropper. Implement 802.1x. IEEE 802.1x provides very strong security. Although it can use the same data encryption scheme as WEP, it enables stronger authentication as well as the ability to dynamically vary the encryption keys. · · · Basic Installation and Configuration August 2003 3-4 Reference Manual for the ME103 802.11b ProSafe Wireless Access Point Installing the ME103 802.11b ProSafe Wireless Access Point Before installing the ME103 802.11b ProSafe Wireless Access Point, you should make sure that your Ethernet network is up and working.

However, the ME103 is also set, by default, to be a DHCP client. So, if the ME103 has not yet been installed, and there is no DHCP server on the network, you can log in to the ME103 using its default IP address. Otherwise, you should use either the NetBIOS login described in "How to Log In to the ME103 Using Its Default NetBIOS Name" on page 3-8 or the procedure described in "Set up the ME103 Access Point" on page 3-5" which uses a static IP configuration. Note: The computer you are using to connect to the ME103 should be configured with an IP address that starts with 192.168.0.x and a Subnet Mask of 255.255.255.0. 2. Open a Web browser such as Internet Explorer or Netscape Navigator. 3. Connect to the ME103 by entering its default address of http://192.168.0.224 into your browser. 1. 4.

The Basic Wireless Settings menu will appear, as shown below. Figure 3-8: Basic Wireless Settings menu The Basic Wireless Settings menu options are discussed below: · Country Domain. This field identifies the region where the ME103 can be used. It may not be legal to operate the wireless features of the wireless access point in a region other than one of those identified in this field. There is no default country domain, and the channel is set to 11. Unless a country domain is selected, the channel cannot be changed. Channel. This field identifies which operating frequency will be used. It should not be necessary to change the wireless channel unless you notice interference problems or setting up the ME103 near another access point. See "Wireless Channels" on page B-7 for more information on wireless channels. ­ Access points use a fixed channel. You can select the channel used. This allows you to choose a channel which provides the least interference and best performance. In the USA and Canada, 11 channels are available. If using multiple access points, it is better if adjacent access points use different channels to reduce interference. The recommended channel spacing between adjacent access points is 5 channels (for example, use channels 1 and 6, or 6 and 11). In "Infrastructure" mode, wireless stations normally scan all channels, looking for an access point. If more than one access point can be used, the one with the strongest signal is used. This can only happen when the various access points are using the same SSID. · ­ ­ 3-11 August 2003 Basic Installation and Configuration Reference Manual for the ME103 802.11b ProSafe Wireless Access Point · Wireless Network Name (SSID). The SSID is also known as the wireless network name. Enter a value of up to 32 alphanumeric characters. In a setting where there is more than one wireless network, different wireless network names provide a means for separating the traffic. Any device you want to participate in a particular wireless network will need to use the SSID. The ME103 default SSID is: NETGEAR. ­ ­ A group of Wireless Stations and a single access point, all using the same ID (SSID), form a Basic Service Set (BSS). Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each other. However, some access points allow connections from wireless stations which have their SSID set to "any" or whose SSID is blank (null). A group of wireless stations and multiple access points, all using the same ID (ESSID), form an Extended Service Set (ESS). Different access points within an ESS can use different channels. To reduce interference, it is recommended that adjacent access points should use different channels. As wireless stations physically move through the area covered by an ESS, they will automatically change to the access point which has the least interference or best performance. This capability is called roaming. ­ ­ ­ Understanding Basic Wireless Security Options The table below identifies the various basic wireless security options. A full explanation of these standards is available in Appendix B, "Wireless Networking Basics". Figure 3-9: Basic Wireless Security options Basic Installation and Configuration August 2003 3-12 Reference Manual for the ME103 802.11b ProSafe Wireless Access Point Table 3-1. Field Network Authentication Basic Wireless Security Options Description You can select the following network authentication options: · Open: the ME103 does not perform any authentication. However, if the 802.1x option is configured, authentication of connections can be performed by a RADIUS server. · Shared: this is for shared key authentication. The SSID and data are encrypted. You can select the following data encryption options: · Disabled · 64- or 128-bit WEP With Open Network Authentication and 64- or 128-bit WEP Data Encryption, the ME103 does perform 64- or 128-bit data encryption but does not perform any authentication. However, if the 802.1x option is configured, authentication of connections will be performed by a RADIUS server. If WEP is enabled, you can manually or automatically program the four data encryption keys. These values must be identical on all PCs and access points in your network (key 1 must be the same for all, key 2 must be the same for all, etc.) There are two methods for creating WEP encryption keys: · Passphrase. These characters are case sensitive. Enter a word or group of printable characters in the Passphrase box and click the Generate button. Note: Not all wireless adapters support passphrase key generation. · Manual. These values are not case sensitive. 64-bit WEP: enter 10 hexadecimal digits (any combination of 0-9, a-f, or A-F). 128-bit WEP: enter 26 hexadecimal digits (any combination of 0-9, a-f, or A-F). Data Encryption Network Key Configure 802.1x WEP security can be compromised by a determined snoop. If you require the kind of strong security that is extremely difficult to compromise, use 802.1x RADIUS authentication as explained in "Configuring Advanced Security 802.1x Options" on page 5-1. For an explanation of 802.1x security, please see "Understanding 802.1x Port Based Network Access Control" on page B-9. 3-13 August 2003 Basic Installation and Configuration Reference Manual for the ME103 802.11b ProSafe Wireless Access Point Information to Gather Before Changing Basic Wireless Settings Before customizing your wireless settings, print this form and record the following information. If you are working with an existing wireless network, the person who set up or is responsible for the network will be able to provide this information.
