If you are using Ethernet to connect your gaming device directly to your modem or router, then a gaming router may not be necessary. Ethernet provides a stable and reliable connection with lower latency and faster speeds compared to Wi-Fi, and a high-quality Ethernet cable should be sufficient for most gaming needs.

However, a gaming router can still provide some benefits, even when using Ethernet. For example, gaming routers often have advanced Quality of Service (QoS) features that prioritize gaming traffic and reduce latency, even when other devices on the network are using bandwidth-intensive applications such as streaming or downloading. They may also have additional features such as advanced security settings and customizable settings that can be beneficial for gaming.

Furthermore, a gaming router may be useful if you have multiple gaming devices or other devices that require high-speed and low-latency connections, such as virtual reality headsets or streaming devices. Gaming routers typically have more powerful processors and better network hardware than standard routers, which can handle multiple connections and bandwidth-intensive applications more efficiently.

In summary, while a gaming router may not be essential when using Ethernet, it can still provide benefits such as advanced QoS features and additional network hardware that can improve your gaming experience. If you have multiple gaming devices or other devices that require a fast and stable connection, a gaming router may be worth considering.
