Ethernet is generally better for gaming than using Wi-Fi through a router, especially for online gaming, where a stable and fast connection is crucial for a good experience.


Using an Ethernet cable to connect your gaming device directly to your modem or router can provide a more stable and reliable connection with lower latency and faster speeds. Ethernet connections are less prone to interference and can provide a dedicated connection between your device and the internet, without competing with other devices for bandwidth.


On the other hand, Wi-Fi connections through a router can be affected by various factors such as distance, interference, and the number of devices connected to the network. Wi-Fi signals can be blocked by walls and other physical obstacles, and the signal strength can degrade over distance. Additionally, Wi-Fi signals are shared between devices, which can lead to slower speeds and higher latency.


That being said, if you have a high-end gaming router and a stable Wi-Fi connection, you may be able to achieve similar performance to Ethernet. Modern routers with advanced features such as Quality of Service (QoS) can prioritize gaming traffic and reduce latency, and some routers also support the latest Wi-Fi standards such as Wi-Fi 6, which can provide faster speeds and better performance.


In general, for the best gaming experience, it's recommended to use Ethernet whenever possible, but if you have to use Wi-Fi, make sure you have a high-quality router and try to reduce any sources of interference.
