Most (not all) of those devices are made to a specific operating system (so I have a bunch of old PCMCIA and USB wireless devices collecting dust). <br />
<br />
I use the Nokia CS-18. It works a treat on my Windows 7 Thinkpad and I have tested it and it works in Windows 8 as well. It should work in XP but I have not tested that (XP is dead). It works in Vista (I have done that). <br />
<br />
The CS-18 does 3G in most places but is works in a 4G zone as well. <br />
<br />
The CS-18 has an included SIM so it can easily be shared and one party picks up the bill. <br />

Wireless networking is anything related to the transfer of data between two (or more) devices without the use of a physical connection, ranging from getting advice on a new Bluetooth headset to configuring sophisticated enterprise level networks.

Wireless Networking

Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. The key hardware components of a wireless computer network include adapters, routers and access points, antennas and repeaters.

Wireless Hardware

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
