A Quora Q & A I thought to share

Is it still worth having wired Ethernet connection to home computers as many wireless routers have faster networks connections?

A modern wired connection is 1,000 Mbit/s (1 Gbit/s). It has no radio interference, no channel saturation. It’s a solid, fast, trouble-free connection. WiFi speeds are total fiction. Typical data speeds with multiple users doing different things at the same time are about half the “maximum” data rate. Advanced features like beam forming and Mu-MIMO tout greatly increased speeds, but if the performance is measured they make virtually no difference. WiFi is subject to radio interference. If you and whichever neighbors happen to be on the same WiFi channel as you are all busy using WiFi, the channel won’t be able to carry all the traffic and will saturate. WiFi will slow, sometimes stopping, then start up again in a minute or so. WiFi works very well in many home environments because its typical performance is greater than most homes need. But if you are interested in performance, you are not interested in WiFi.
