WiFi vs. Plugged In Speeds

Each Wi-Fi standard is rated according to its maximum theoretical network bandwidth. The newest, 802.11ac offers up to 1 Gbps (1,000 Mbps). However, the performance of Wi-Fi networks practically never approach these theoretical maximums, usually performing at about half of peak speed. If you compare 300 Mbps WiFi to wired Fast Ethernet at 100 Mbps, the Ethernet connection most often outperforms in real world usage.
Wi-Fi networks have a range that is limited by the transmission power, antenna type, the location, physical obstacles, such as walls, number of other devices sharing the signal, and the environment. A typical indoor wireless router might have a solid range of about 32 meters (105 ft). Distance from the source also degrades performance. The fastest theoretical WiFi 802.11 ac is maximum speed of 866.7 Mb/s.

Plugged in (Ethernet) offers advantages, such as faster speeds, lower latency, and no wireless interference problems.  A wired Ethernet connection can theoretically offer up to 10 Gb/s.

Bottom line, when it comes to speed necessary for streaming movies and TV WiFi may be more convenient, but is much slower and may cause delays and hesitations. Also, when looking at your speed, consider 10Mbs as the absolute minimum for streaming - and more is better.


Incidentally, no matter how fast your WiFi is within your house, it does not increase the speed of the connection between your house and the Internet.
