Your home network has invisible noise, and it might be slowing everything down
Wi-Fi is officially capable of handling upload and download speeds that can theoretically rival Ethernet connections, but why is it so hard to achieve these theoretical speeds in the real world? The answer has to do with bandwidth, congestion, and noise. When using an Ethernet cable to hardwire a device to your home network, that device — whether it be a PC, streaming box, or gaming console — has a private “fast lane” to your router or switch. The common pain points of wireless connections, like physical interference, congestion, or dropped signals, aren’t an issue. The device has a direct connection to your home network, and nothing can get in the way. Basic networking best practices tell you to use Ethernet over Wi-Fi when possible to avoid congestion and interference, among other wireless problems. Naturally, the next question to ask is: what’s actually causing the congestion and interference on my home wireless network? Some of the root causes are simple. Physical obstructions such as walls or floors and competing appliances like microwaves can create interference. …
