Wi-Fi Cards act as wireless adapters, helping devices that would not normally function over Wi-Fi networks, such as personal computers, function over Wi-Fi connections.
However, sometimes using Wi-Fi is simply too convenient to be avoided.
As Wi-Fi is typically thought of as a weaker and less stable connection, with more fluctuations and variances throughout a period of time of usage, serious computer users such as gamers tend not to rely on it. Wi-Fi cards help to provide wireless internet speeds and connectivity that rival those of wired connections.
