Wireless internet is very convenient. It’s much easier to simply connect your computer or phone to a wireless network instead of dealing with the network cables. Since wireless internet is a recent technology, it is often assumed that wi-fi is superior in every way to wired connections. It is true that wi-fi is easier to use than wired connections, but wired technology does have numerous advantages over wireless.
Wired connections are much faster than wi-fi. They also are not vulnerable to wireless interference. Some electric devices like microwaves can emit wireless signals and radiation that can interfere with wi-fi signals. Wi-fi signals also cannot penetrate objects or walls that are thicker than a certain amount, depending on the exact frequency the signal uses. In addition, wi-fi signals are much less secure than wired connections, since they can be potentially connected to by anyone in range of the signal.
All of these are things to consider the next time you are setting up a home network, or if you notice your wi-fi connected device being slow or acting strange. It could be that your wi-fi signal is being interfered with or having trouble transmitting through something.
