Wi-Fi not working? How to fix your Wi-Fi problems

Wi-Fi refers to a wireless local area network that utilized high frequency signals to transport and obtain data. Wi-Fi connects the device to the Internet in order to use Safari, iMessaging, and a variety of other app services that require a connection. The iPhone, iPod touch, iPad, and Mac computers all come with wireless capabilities. However, the cellular models (iPhone and iPad) also come with the option of connecting to the phone service carrier’s cellular 3G or 4G network.

When Wi-Fi is turned on for the device, it will automatically connect to the established preferred network when a feature that uses the Internet is accessed. If the normal network is not available, the smart device knows to connect to any network that has been used in the past. Depending on the type of network, sometimes a password will be required for encryption purposes. The strength of the connection can be clearly viewed by the user on the top left of the screen. Most Wi-Fi networks are free to use, come with unlimited usage, and are faster than cellular counterparts.
