A comparison between a wired Gigabit Ethernet network and a Wi-Fi network revealed that a wired connection has advantages and disadvantages over a wireless router. Ethernet networks are faster, less expensive, easier to maintain and unaffected by radio interference. The main issues with a Gigabit Ethernet network are the installation of the network, the poor support for voice and video traffic, and the tethering of portable, wireless devices.
Gigabit Ethernet is a common technology used to build local area networks. It is in competition with Wi-Fi connected networks to dominate networking technology in both the home and office. The increasing popularity of wireless routers is turning the wired Ethernet home network into a rarity, as of 2014. In fact, several popular computer models, such as Apple's MacBook Air, lack a port for an Ethernet connection. However, there is an option, called powerline networking, that allows users to keep the speed and reliability of an Ethernet network while gaining the convenience of a wireless network. The idea is to utilize two adapters by connecting one of them to the router with an Ethernet cable and then doing the same for the computer. Powerline networking also solves the problem of weak and blocked Wi-Fi signals.
