Are you running the wireless network in ad-hoc mode or
infrastructure mode?
There are two modes of configuring your wireless adapter: ad-hoc mode or infrastructure mode. In
an ad-hoc wireless network, there is no access point. Each node communicates with any other node
directly. (A node is a network connection point. For example, a PC in a LAN is a node.)
Support information card
If you don’t have everything listed above, see the Support information card for contact
information. If the support information card is missing, go to
www.NETGEAR.com/support_contacts.html to obtain contact information.

In the infrastructure mode, the wireless access point bridges between the wired LAN and wireless
network. Connecting multiple access points via a wired Ethernet backbone can further extend the
wireless network coverage. As a mobile computing device moves out of the range of one access
point, it moves into the range of another. As a result, wireless clients can freely roam from one
Access Point domain to another and still maintain a seamless network connection.

the NETGEAR HE102 802.11a Wireless Access Point) first, before you set up this wireless adapter.

Note: Twenty-four bits in the encryption key are factory preset and not modifiable.
A 64-bit encryption key can be represented by ten (10) hexadecimal digits. For a
128-bit encryption key, twenty-six (26) hexadecimal digits need to be provided. For
a 152-bit encryption key, thirty-two (32) hexadecimal digits need to be provided.
What is the SSID for your wireless network?
The Service Set Identification (SSID) is an alphanumeric character string identifying the
wireless local area network. The HA501 Wireless Adapter can only communicate with wireless
NICs or access points configured with the same SSID. For the access point and wireless nodes
to communicate with each other, all must be configured with the same SSID. Either the SSID
for your wireless network was assigned in a preexisting wireless network or, if there was no
preexisting wireless network, you must create the SSID just as you would create a network
name, using from 1 to 32 characters and not including any spaces or hyphens between characters.
Note: Hexadecimal digits are the first ten numbers of the decimal system (0, 1, 2,
3, 4, 5, 6, 7, 8, and 9) and the letters A, B, C, D, E, and F. Your choice of characters
is arbitrary. You might use, for example, a phone number. (Do not use an obvious
one, such as your office phone number). The table below shows you some
examples of encryption settings.
SSID: _________________________________________
Which wireless channel to use?
When the HA501 Wireless Adapter is configured to operate in Infrastructure mode, it auto-
matically scans through all eight available channels (three when in turbo mode) for the closest
access point to associate with. When the HA501 Wireless Adapter is configured to operate in
ad-hoc mode, one of the HA501 Wireless Adapters will automatically operate as a virtual access
point. There is no need to set up the wireless channel for the wireless adapter.
What is the WEP Encryption key?
The absence of a physical connection between nodes makes the wireless links vulnerable to
information theft. To provide a certain level of security from eavesdroppers and hackers, you
can (1) enable WEP encryption and (2) create your shared key in the security table of the
configuration utility. The HA501 Wireless Adapter supports “shared key” encryption with key
sizes from the industry standard 64-bit, 128-bit and 152-bit.
The Shared Key, as well as the key content used by the HA501 Wireless Adapter and the wire-
less access point or other wireless nodes in the same network, must be the same.

Installation Instructions for Windows 2000
1. If you have chosen to install the card with the PC turned off, turn the power on now. The
new hardware is found. Click “Next”.
Install the Wireless Adapter
2
After unpacking the box and determining all the configuration information, you’re ready to
install the wireless adapter.
2. Insert the HA501 Resource CD-ROM into your CD-ROM drive.
3. In the next window, select "Search for a suitable driver for my device (recommended),”
and then click “Next.”
Install the Wireless Adapter
The HA501 Wireless Adapter is hot swappable and supports hot insertion, which means that
you can insert it into a notebook computer that is either powered on or shut down. You must
install the HA501 Wireless Adapter before installing the network driver.
Before you proceed with the installation steps, decide on a name for your network and for each
PC (this information is different from the wireless parameters previously mentioned. Each
network much have the same workgroup name and each PC must have a unique computer
name for Microsoft networking to work properly.)
Install the Adapter Driver (First Time Installation)
This section explains the installation of the Windows 2000 adapter driver. Other versions of
Microsoft Windows may respond with different dialog boxes, or the dialog boxes may open
in a different sequence than those shown in this guide, but should prompt you for the
same information. If you are reinstalling or upgrading the driver, you may need to contact
NETGEAR Technical Support for advice. You will find contact information in the Support
information card that came with your adapter.
Note: You may need your Windows 2000 CD-ROM and the HA501 Resource CD-
ROM ready to use in the installation.
Note: If the “insert disk” dialog box opens and the “Please insert the disk labeled
Windows 2000…” message appears at any time during the installation process,
insert the Windows 2000 CD-ROM and click “OK.” Then follow the next step in the
instructions.
Note: To install the driver on Windows XP, 2000, or NT 4.0, you must log in with
Administrator privilege.
Note: Users of Windows 98 or Me need to install the Windows Message Interface
(WMI) to complete the installation of the HA501 Configuration Utility

4. In the next Found New Hardware Wizard window, select the “CD-ROM drives” search
option and click “Next”.
6. Click “Yes” when asked if you still want to install the driver when it is not digitally signed.
7. Click “Finish” at the final Found New Hardware wizard window.
5. In the Found New Hardware Wizard window, make sure that the driver name is
“D:\netha501.inf” assuming that the driver letter for the CD-ROM drive is “D:”. (You
should see the correct drive letter that represents your PC’s CD-ROM.)

FOR HOME OR OFFICE USE
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interfer-
ence to radio or television reception, which can be determined by turning the equipment off and on, the user is encour-
aged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna,
• Increase the separation between the equipment and receiver,
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected,
• Consult the dealer or an experienced radio/TV technician for help.
Radio Frequency Interference Requirements
This device is restricted to indoor use due to its operation in the 5.15 to 5.25 GHz frequency range. FCC requires this
product to be used indoors for the frequency range 5.15 to 5.25 GHz to reduce the potential for harmful interference
to co-channel Mobile Satellite systems. High power radars are allocated as primary users of the 5.25 to 5.35 GHz and
5.65 to 5.85 GHz bands. These radar stations can cause interference with and /or damage this device.
