Frequently Asked Questions - RangeMax WNDA3100 NETGEAR

How do I install the Netgear WNDA3100 adapter?

Insert the Resource CD and run the installer. Do not connect the adapter until prompted. Follow the on-screen instructions. When asked, plug the adapter into a USB port. The Smart Wizard will guide you through connecting to a wireless network.

Why is my WNDA3100 LED not lit?

The adapter may not be properly connected or the software may not be loaded. Try removing and reinserting the adapter. Check the Windows Device Manager to ensure it is recognized. Reload the software if necessary or try a different USB port.

How can I improve wireless performance with the WNDA3100?

Place the adapter at least 4 feet from the router. Avoid large metal surfaces, microwaves, and cordless phones (2.4/5 GHz). Use the Advanced Settings to select 5 GHz if there is interference. Ensure your computer has USB 2.0 for full speed.

What security modes does the WNDA3100 support?

It supports WEP (64/128-bit), WPA-PSK, and WPA2-PSK (AES). Configure security in the Smart Wizard Settings tab. The network name (SSID) and security settings must match your access point.

How do I connect to a hidden network?

In the Smart Wizard, select the network from the drop-down list. If it is hidden, the SSID field will be blank. Select it anyway, then enter the SSID manually when prompted. You must also provide the correct security key.

Can I use the WNDA3100 with Windows Vista?

Yes, the adapter supports Windows Vista. During installation, if a driver verification message appears, click 'Install this driver software anyway'. For Vista, you can also use the native wireless configuration if you prefer.

What does the LED color indicate?

Amber indicates connection at 2.4 GHz; Blue indicates 5 GHz. Solid means connected but idle; Blinking means data is being sent or received. Slow blinking (alternating colors) means the adapter is scanning for a network.

How do I set up an Ad Hoc (computer-to-computer) network?

In the Smart Wizard Settings tab, select Computer-to-Computer (Ad Hoc) network type. Enter a network name (SSID). Click Initiate Ad Hoc and choose the wireless standard and channel. Configure each computer with a static IP address in the same subnet.

My throughput is only 54 Mbps or 14 Mbps. Why?

If you are getting 54 Mbps, you may be connecting to an 802.11g network (not N). If 14 Mbps, your computer likely has a USB 1.1 port, which limits speed. Use a USB 2.0 port for full performance. Also, distance and interference can reduce speed.

How do I uninstall the WNDA3100 software?

Go to Start > Control Panel > Add or Remove Programs (or Programs and Features). Select RangeMax Dual Band Wireless-N USB Adapter WNDA3100 and click Remove. Alternatively, use the shortcut in the Start Menu under the NETGEAR program group.

Chapter 1 Basic Setup

This chapter describes how to install your RangeMax Dual Band Wireless-N USB Adapter WNDA3100 and set up basic wireless connectivity on your wireless local area network (WLAN). Advanced wireless network set up is covered in “Network Connections and Wireless Security” in Chapter 2.

Note: Indoors, computers can easily connect to 802.11 wireless networks at distances of several hundred feet. Because walls do not always block wireless signals, others outside your immediate area could access your network. It is important to take steps to secure your network from unauthorized access. The wireless USB adapter provides highly effective security features, which are covered in “Using Wireless Security Features” in Chapter 2. Use the security features appropriate to your needs.

What You Need Before You Begin

You need to verify that your computer meets the minimum system requirements and identify the wireless network settings of the WLAN where you will connect before you can set up your wireless USB adapter and connect.

Verify System Requirements

Before installing the NETGEAR RangeMax Dual Band Wireless-N USB Adapter WNDA3100, please make sure that these minimum requirements have been met:

- You must have a PC with a Pentium 300 MHz or higher compatible processor with an available USB 2.0 or 1.1 port.

Note: The maximum speed of a USB v2.0 port is 480 Mbps. If your computer has a USB v1.1 port, the WNDA3100 is limited to that port's maximum speed, which is 14 Mbps.

- A C D d r i v e .

• 5 Mbytes of free hard disk space.
• Vista, Windows XP Home, or Windows XP Professional. Some versions of Windows ask for the original Windows operating system installation files to complete the installation of the WNDA3100 driver software.

Note: Windows XP users must install SP2 or install the KB822603 hot fix (update), which fixes the USB 2.0 host controller driver. Go to the following link to install the hot fix: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=733dd867-56a0-4956-b7fe-e85b688b7f86

Observe Wireless Location and Range Guidelines

For best performance, place the wireless USB adapter at least 4 feet (over 1 meter) away from the wireless router or access point.

Computers can connect over wireless networks indoors at a range that varies significantly based on the physical location of the computer with the wireless USB adapter. For best results, avoid potential sources of interference, such as the following:

• Large metal surfaces
- Microwaves
• 2.4 GHz or 5 GHz cordless phones

Note: If there is 2.4 GHz interference at your location, such as from a cordless phone, you can change the setting to 5 GHz for better wireless throughput. See “Advanced Settings” on page 2-17.

In general, wireless devices can communicate through walls. However, if the walls are constructed with concrete, or have metal, or metal mesh, the effective range decreases if such materials are between the devices.

What Is in the Box

The product package should contain the following items:

• NETGEAR RangeMax Dual Band Wireless-N USB Adapter WNDA3100
- USB cable and adapter cradle
- Installation Guide for the NETGEAR RangeMax™ Dual Band Wireless-N USB Adapter WNDA3100

Note: The channel number differs depending on the country. The connection speed automatically defaults to the highest speed.

Wireless Security

Many networks use wireless security to encrypt wireless data communications. If you try to connect to a network with wireless security, the Smart Wizard detects it. Before you can use that network, you must set up the WNDA3100 with exactly the same kind of wireless security settings. The main types of wireless security used for home networks are the following:

• Wi-Fi Protected Access 2 Pre-Shared Key (WPA2-PSK)
• Wi-Fi Protected Access Pre-Shared Key (WPA-PSK)
• Wired Equivalent Privacy (WEP)

For more information about wireless security, see the wireless reference document at http://documentation.netgear.com/reference/enu/wireless/index.htm.

In addition to the wireless security features, networks should use LAN network security features such as requiring a user name and password to access the shared resources in the network.

Using Wireless Security Features

You can strengthen the security of your wireless connection by enabling Wired Equivalent Privacy (WEP) encryption of the wireless data communications. Or, you can use WPA-PSK (Wi-Fi Protected Access Pre-Shared Key) encryption. For more information about wireless security, see the link to “Wireless Communications:” in Appendix B.

In addition to the WNDA3100 wireless security features, you should also configure appropriate LAN network security features such as requiring a user name and password to access the shared resources in your network.

Chapter 3 Wireless Network Performance

This chapter explains how to use your RangeMax Dual Band Wireless-N USB Adapter WNDA3100 to connect to your wireless local area network (WLAN) and how to set up wireless security for the wireless USB adapter so that it matches the wireless security settings for your network.

Optimizing Wireless Performance

The speed and operating distance or range of your wireless connection can vary significantly based on the location of the wireless router. You should choose a location for your router that will maximize the network speed.

The following list describes how to optimize wireless router performance.

- Identify critical wireless links.

If your network has several wireless devices, decide which wireless devices need the highest data rate, and locate the router near them. Many wireless products have automatic data-rate fallback, which allows increased distances without losing connectivity. This also means that devices that are farther away mighty be slower. Therefore, the most critical links in your network are those where the traffic is high and the distances are great. Optimize those first.

- Choose placement carefully. For best results, place your router:

• Near the center of the area in which your computers will operate.
• In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls).

- Avoid obstacles to wireless signals.

• Keep wireless devices at least two feet from large metal fixtures such as file cabinets, refrigerators, pipes, metal ceilings, reinforced concrete, and metal partitions.
• Keep the devices away from large amounts of water such as fish tanks and water coolers.

- Reduce interference.

Avoid windows unless communicating between buildings.

Place wireless devices away from various electromagnetic noise sources, especially those in the 2400–2500 MHz frequency band. Common noise-creating sources are:

• Computers and fax machines (no closer than 1 foot)
• Copying machines, elevators, and cell phones (no closer than 6 feet)
• Microwave ovens (no closer than 10 feet)

- Choose your settings.

• Use a scanning utility to determine what other wireless networks are operating nearby, and choose an unused channel.
• Turn off SSID Broadcast, and change the default SSID. Other nearby devices might automatically try to connect to your network several times a second, which can cause significant performance reduction.

Optimizing Your Network Bandwidth

The speed of network connections depends on the type of equipment that you use. Try to use high-speed technologies for network connections with the heaviest traffic to avoid lower-speed bottlenecks in the path. The following figure shows a home network that includes many different connection speeds.

Figure 3-1

In the network shown in the previous figure, the two PCs with gigabit (1000 Mbps) Ethernet adapters have a gigabit connection through the router to the storage server. With a high-speed router this connection allows for extremely fast backups or quick access to large files on the server. The PC connected through a pair of Powerline HD adapters is limited to the 200 Mbps speed of the Powerline HD connection. Although any of the links in this example would be sufficient for high-traffic applications such as streaming HD video, the use of older devices such as 10 Mbps Ethernet or 802.11b wireless would create a significant bottleneck.

In planning your network, think about which tasks will have the heaviest traffic flow between them. Examples are:

• A media center in one room streaming high-definition video from a server in another room
• A storage device that is used for backing up your computers

Overview of Home and Small Office Networking Technologies

Common connection types and their speed and security considerations are:

- Broadband Internet

Your Internet connection speed is determined by your modem type, such as ADSL or cable modem, as well as the connection speed of the sites to which you connect, and general Internet traffic. ADSL and cable modem connections are asymmetrical, meaning they have a lower data rate to the Internet (upstream) than from the Internet (downstream). Keep in mind that when you connect to someone else who also has an asymmetrical connection, the data rate between your sites is limited by each side's upstream data rate. A typical residential ADSL or cable modem connection provides a downstream throughput of about 1 to 3 megabits per second (Mbps). Newer technologies such as ADSL2+ and Fiber to the Home (FTTH) 1 increase the connection speed to tens of Mbps.

- Wireless

A high-speed wireless router can provide a wireless data throughput of up to 300 Mbps using technology called multiple-input multiple-output (MIMO), in which multiple antennas transmit multiple streams of data. The use of multiple antennas also provides excellent range and coverage. With the introduction of the newer WPA and WPA2 encryption and authentication protocols, wireless security is extremely strong.

To get the best performance, use newer adapters such as RangeMax adapters for your computers. A high-speed router might be compatible with older 802.11b and 802.11g adapters, but the use of these older wireless technologies in your network can result in lower throughput overall (typically less than 10 Mbps for 802.11b and less than 40 Mbps for 802.11g). In addition, many older wireless products do not support the latest security protocols, WPA and WPA2.

- Powerline

For connecting rooms or floors that are blocked by obstructions or are distant vertically, consider networking over your building's AC wiring. NETGEAR's Powerline HD family of products delivers up to 200 Mbps to any outlet, while the older-generation XE family of products delivers 14 Mbps or 85 Mbps. Data transmissions are encrypted for security, and you can configure an individual network password to prevent neighbors from connecting.

The Powerline HD family of products can coexist on the same network with older-generation XE family products or HomePlug 1.0 products, but they are not interoperable with these older products.

- Wired Ethernet

As Gigabit Ethernet ports become common on newer computers, wired Ethernet remains a good choice for speed, economy, and security. Gigabit Ethernet can extend up to 100 meters with twisted-pair wiring of CAT-5e or better. A wired connection is not susceptible to interference, and eavesdropping would require a physical connection to your network.

Note: Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, can lower actual data throughput rate.

Assessing Your Speed Requirements

Because your Internet connection is likely to operate at a much lower speed than your local network, faster local networking technologies might not improve your Internet experience. However, many emerging home applications require high data rates. For example:

• Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss can disrupt your video, plan to provide at least twice the capacity you need.
• Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so a congested network or a noisy link can cause problems.

- Backing up computers over the network has become popular due to the availability of inexpensive mass storage. Table 3-1 shows the time to transfer 1 gigabyte (1 GB) of data using various networking technologies.

Table 3-1. Theoretical Transfer Time for 1 Gigabyte

Network Connection Theoretical Raw Transfer Time
Gigabit Wired Ethernet 8 seconds
RangeMax Dual Band Wireless-N 26 seconds
Powerline HD 40 seconds
100 Mbps Wired Ethernet 80 seconds
802.11g wireless 150 seconds
802.11b wireless 700 seconds
10 Mbps Wired Ethernet 800 seconds
Cable Modem (3 Mbps) 2700 seconds
Analog Modem (56 kbps)	144,000 seconds (40 hours)

Throughput is only 54 Mbps or only 14 Mbps.	The RangeMax Dual Band Wireless-N USB Adapter WNDA3100 can operate at faster speeds.• At 54 Mbps you are probably connecting to a standard 802.11g network. See Chapter 3, “Wireless Network Performance”.• If you do not have a USB 2.0 port on your PC, the throughput is limited to the 14 Mbps of the USB 1.1 standard.
The Smart Wizard keeps asking me to save settings.	If you change the settings, the Smart Wizard offers you the chance to save the changes. To avoid this prompt, simply click Apply before you close the Smart Wizard.
Two WNDA3100 icons are in the system tray.	You have an older software version installed on your system and it needs to be removed. See “Removing the WNDA3100 Software” in Chapter 1 or “Upgrading the WNDA3100 Software” in Chapter 1.
I can connect to the access point, but not to the other computers on the network or to the Internet.	This could be a physical layer problem or a network configuration problem.1. Check to make sure that the access point is physically connected to the Ethernet network.2. Make sure that the IP addresses and the Windows networking parameters are all configured correctly. See the link to “Internet Networking and TCP/IP Addressing:” in Chapter B.3. Restart the cable or DSL modem, router, access point, and computer.
Ho can I view the IP address for the wireless USB adapter?	To view the RangeMax Dual Band Wireless-N USB Adapter WNDA3100 IP address, click the WNDA3100 icon to open the Smart Wizard. Then check the IP address in the About page.
No IP address is assigned to the RangeMax Dual Band Wireless-N USB Adapter WNDA3100.	This can occur if you upgraded your RangeMax Dual Band Wireless-N USB Adapter WNDA3100 software and did not reboot your system.• Either restart your computer, or connect to a different access point.• It does not usually help to shut down the Smart Wizard or disable or enable the wireless USB adapter.
