A friend asked me the other day whether it’s best to connect his computer to his router via WiFi or over a wired Ethernet connection.
My answer: It depends.
First of all, is the computer in question sitting near the router or is it located in another room in the house?
If it’s possible (and practical) to run a cable between the two locations, a wired connection between your computer and router offers a number of benefits.
In most cases a wired Ethernet connection will likely to be faster than the connection to your ISP so speed shouldn’t really be a factor in your decision (assuming you don’t have a Gigabit or faster fiber connection of course).
In almost all cases I would go with a wired connection between the computer and router, if running the cable is practical.
Why? Because WiFi signals fluctuate and even go out entirely at times. A wired connection should be rock solid virtually all the time.
If the computer is far way from the router or if running an Ethernet cable will be problematic, then opt for WiFi.
For the sake of convenience, it’s probably best just to use Wi-Fi to connect a laptop even when using it near the router. But if the only place you ever use the laptop is near the router go ahead and use an Ethernet cable.
Bottom line: Whenever possible and practical to do so, use a wired Ethernet connection. Otherwise, go with WiFi.
