The need most common is to connect to a WIFI router located inside our own house, but that for the distance we need a WIFI adapter with receiver stable. In the market is having network cards WIFI with free PCI and PCI-Express that connect directly to the motherboard of the PC, but the most common is to buy a USB adapter for WIFI antenna. They are inexpensive and easy to install.
2 - Models of frequency of WIFI:
The wifi adapters work similarly on Windows, Linux and MAC.
In Android that is a Linux system closed, it is necessary that the device contains the driver for the WIFI antenna from the factory. Consult the manufacturer of the Android device that model of chip WIFI support and buy a USB adapter of the same model of chip for it to work.
Manufacturers provide the drivers for these operating systems. Check in the tab of the product the supported systems or to ask a technical store support. Models WIFI N are compatible with all Windows including Windows 7, 8, and Windows 10 or later.
Receptor WIFI b / g are the classics that reach speeds of up to 54mbps transmission, do not have much scope to external.
The receptors WIFI technology N reach 150mbps, and N enhanced with two antennas come to 300Mbps ideal for reaching up to 150 metres indoors and 300 metres outdoors. For transmission of large size files, games, or video you need wifi N.
WIFI 11AC is the new technology that reaches up to 867Mbps thanks to the WIFI technology AC and the USb 3.0 port an example is the adapter Alfa Network AWUS036AC 802.11 ac AC1200 (Works with all Windows and MAC Yosemite 10.10 or later)
