Chapter 1
Installation with Custom Setup
This chapter explains custom installation for your Wireless-N USB Adapter. With custom setup
you can specify where the files are installed. You can also choose whether or not you want to
install the Smart Wizard.
What You Need Before You Begin
To install the wireless-N USB adapter, you need:
• A PC with a Pentium300 MHz or higher compatible processor with an available USB port.
• A CD drive.
• 15Mbytes of free hard disk space.
• Windows7, 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 WNA1100 v1 driver software.
Note: For help with express installation, see the NETGEAR Wireless-N 150 USB Adapter
WNA1100 Installation Guide.
Note: The maximum speed of a USB v2.0 port is 480 Mbps. If your computer has a
USB v1.1 port, the wireless-N USB adapter is limited to that port’s maximum
speed, which is 14 Mbps.
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 this link to install the hot
fix: http://www.microsoft.com/downloads/

Observe Wireless Location and Range Guidelines
For best performance, place the wireless-N 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-N USB adapter. For best results, avoid
potential sources of interference, such as the following:
• Large metal surfaces
• Microwave ovens
• 2.4 GHz cordless phones
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.

1. Insert the Resource CD in your computer’s CD drive. If the CD main screen does not display,
browse the files on the CD and double-click Autorun.exe.
