Choosing a Wireless USB Network Adapter Compatible with Win 7

written by: Bruce Tyson•edited by: Bill Fulks•updated: 4/16/2011

Choosing a wireless USB network adapter compatible with Win 7 may be harder than it seems. Although most new adapters come with Windows 7 drivers, they do not all include 64-bit versions. Used adapters and new adapters from surplus sources present additional uncertainty. Learn more in this article.

    Driver Compatibility

    A wireless USB network adapter compatible with Win 7 will come with a compatible driver. These days, most new adapters come with800px-USB-wireless-adapter  Windows 7 drivers, but some older adapters that are used or are from surplus sources may predate the operating system.

    The version of Windows 7 also makes a difference. An adapter that comes with a driver for Windows 7 may have one for the 32-bit version of Windows, but not the 64-bit version.

    For best practices, a buyer should verify that an adapter either comes with Windows 7 drivers in the box that matches their operating system (32-bit or 64-bit) or that the manufacturer has a compatible driver available for download before completing the purchase.

    Router Compatibility

    When buying a USB network adapter for use with Windows 7, be sure to look for one that needs or exceeds the maximum speed of your primary router. Although most routers and adapters are backward compatible, meaning that they will work with older standards, a Windows users will want to get the most possible speed from their router by getting the fastest card.

    For example, a user who uses Windows primarily at home with an 802.11n compatible router can usually get by with an 802.11b USB network adapter. However, the connection will be at 802.11b speeds. To get the most out of that router, a user would do much better buying an 802.11n network adapter.

    Even when the user's primary router is slow, however, a faster card will still usually pay off because it can connect at faster speeds while at remote locations that have faster routers.

    Check with Microsoft

    Although most wireless USB network adapters will work with Windows 7, they may not be completely compatible. Microsoft maintains a listusb001  of Windows 7 devices that it has tested and verified for compatibility and rates them for 32-bit and 64-bit versions of the operating system. By choosing a model of adapter from the official compatibility list, buyers are assured that their device will work well with their system.

    To use the Windows 7 Compatibility Center, users select either 32-bit or 64-bit at the top of the left column and then select "Wireless Network Cards" in the results filter. Users can then optionally search a particular brand. At the bottom of the left column, users can specify the level of compatibility of adapters displayed on the screen. The ones compatible enough to earn the "Windows Logo" are probably the best ones from which to choose.

    The compatibility list includes all compatible wireless adapters. Be careful to only select the ones that are USB adapters.
