Chapter 2

Basic Installation and Configuration

This chapter describes how to set up your ProSafe Dual Band Wireless-NAccess Point WNDAP350for wireless connectivity to your LAN. This basic configuration will enable computers with 802.11b/g/n or 802.11a/n 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/bg/ng or 802.11a/na 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 WNDAP350 wirelss access point provides highly effective security features which are covered in detail in“Understanding Security Profiles” on page 2-23.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 WNDAP350 that conforms to the “Wireless Equipment 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/g/n or 802.11a/n wireless adapters.

Wireless Equipment 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.

Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the WNDAP350. For complete performance specifications, seeAppendix A, “Default Settings and Technical 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.

The antenna provides better coverage above the access point. Place the access point so that it is either ceiling mounted or mounted on a wall facing the users.

Basic Installation and Configuration

v1.1, November 2009

ProSafe Dual Band Wireless-NAccess Point WNDAP350 Reference Manual

If you are using multiple access points for 11b/bg/ng, 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). For 11a/na, the 6 Channel spacing is not needed.

The time it takes to establish a wireless connection can vary depending on both your security settings and placement. Some types of security connections can take slightly longer to establish and can consume more battery power on a notebook computer.

Understanding WNDAP350 Wireless Security Options

Your wireless data transmissions can be received well beyond your walls by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The WNDAP350 wirelss access point provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs.

Figure 2-1

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 WNDAP350. MAC address filtering adds an obstacle against unwanted access to your network, but the data broadcast over the wireless link is fully exposed.

v1.1, November 2009

ProSafe Dual Band Wireless-NAccess Point WNDAP350 Reference Manual

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, Vista and Unix systems 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 open authentication and WEP data encryption will block all but the most determined eavesdropper.

Use WPA or WPA-PSK. Wi-FiProtected Access (WPA) data encryption provides data security. The very strong authentication along with dynamic per frame rekeying of WPA make it virtually impossible to compromise. Because this is a new standard, wireless device driver and software availability may be limited.

Note: WEP and TKIP provide only legacy rates of operation. So, AES is the recommended solution to use the 802.11n rates and speed.

Installing the WNDAP350 wirelss access point

Before installing the ProSafe Dual Band Wireless-NAccess Point WNDAP350, you should make sure that your Ethernet network is up and working. You will be connecting the access point to the Ethernet network so that computers with 802.11b/g/n or 802.11a/n wireless adapters will be able to communicate with computers on the Ethernet network. In order for this to work correctly, verify that you have met all of the system requirements, shown on“System Requirements” on page 1-5.

Setting up the WNDAP350 wirelss access point

Tip: Before mounting the WNDAP350 in a high location, first set up and test the WNDAP350 to verify wireless network connectivity.

Default is enabled.

Channel/Frequency. From thepull-downmenu, select the channel you wish to use on your wireless LAN. The wireless channel in use will be between 1 to 11 for US and Canada, 1 to 13 for Europe and Australia. The default is channel Auto.

It should not be necessary to change the wireless channel unless you experience interference (shown by lost connections and/or slow data transfers). Should this happen, you may need to experiment with different channels to see which is the best. Alternatively, you can select the Auto channel option for the AP to intelligently pick the channel with least interference. See the article on “Wireless Channels” available on the NETGEAR website. (A link to this article and other articles of interest can be found in Appendix B, “Related Documents.”). When selecting or changing channels, some points to bear in mind:

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).

It should not be necessary to change the wireless channel unless you experience interference (shown by lost connections and/or slow data transfers). Should this happen, you may want to experiment with different channels to see which is the best. See the article on “Wireless Channels” available on the NETGEAR website. (A link to this article and other articles of interest can be found in Appendix B, “Related Documents.”). When selecting or changing channels, some points to bear in mind:

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, 8 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 8 channels (for example, use channels 36 and 44, or 44 and 52).

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 occur when the various access points are using the same SSID.

MCS Index/Data Rate. From thepull-downmenu, select the transmit data rate of the wireless network. Also, depending on the band selected, the set of rates will vary. The default is Best.

Note: Data rate is selected using MCS Index. The actual data rate is computed based on MCS Index, Channel Width, and Guard Interval. When Channel Width selected is Dynamic 20/40MHz or when Guard Interval is selected is Auto, then the data rate for a client depends on associated clients channel width and guard interval capabilities.
