If you are buying a new computer, it is best to select one with a wireless component that is designed for free software like Linux. A card designed for free software gives you improved support. Free software compatible devices also work out of the box.
SparkLAN WPEA-127NI is a high-speed 802.11n pcie module based on Atheros XB114 Reference Design (AR9390-AL1B chipset), which delivers up to 450Mbps data rate. The PCI express module supports the high transmission data rate and reliable performance of 3x3 radios which are ideal for streaming multimedia applications. LoRaWAN is a protocol specification built on top of the LoRa technology developed by the LoRa Alliance. It uses unlicensed radio spectrum in the Industrial, Scientific and Medical (ISM) bands to enable low power, wide area communication between remote sensors and gateways connected to the network. WLRS-590 is the first sub-1GHz SparkLAN wireless module, which is designed & manufactured in a smallest form factor -SiP (System in Package) that is a general purpose SiP for sensor integration.
ThinkPenguin.com currently offers a 802.11N USB card with the AR9170 chipset that guarantees free software compatibility. Also available are MiniPCI wifi cards for laptop computers and USB Bluetooth adapters to connect Bluetooth wireless devices.
Passys sells a PCI card that is Linux compatible (although not free software compatible) for desktop computers.
Wikipedia has additional information on which chipsets and drivers are free software compatible.
- Some other cards are Linux compatible, but not free software compatible. These usually work, but in some cases may not.
Even if your wireless card does not have a driver designed for Ubuntu, you may be able to get it to work using NDISWrapper and a Microsoft Windows driver. This comes at the expense of functionality and reliability. If you get this method working your Internet connection will most likely be very unstable.

Please take a moment and add your card to the wiki if there isn't a page on that device yet. It's very simple, try to follow the format of template but don't worry too much about following guidelines. It's much more important to document your experience for others.
To create a page, simply enter the model # and version in the box (example: dwl-g650vB5) and then click on the Create Device Page button. If there is a page on your device already, open it and add your comments/experience to the existing page.
