Given the potential for Wi-Fi connections to have hiccups, we would always suggest, where possible, to have your gaming PC wired into your router directly. Failing that, buy a Powerline connection. Wireless connections are getting more effective, and Wi-Fi 6 is good enough that wireless VR streaming is now possible. But if latency creeps in there, you might throw up.
The best gaming routers have multiple LAN ports for wired connections—which are preferred—but most differ from ISP-provided gear through the latest Wi-Fi standards, such as 802.11ax, aka Wi-Fi 6. This means faster and more efficient wireless data throughput for a more significant number of devices. That last bit is key to rock-solid wireless performance in an age of smart devices and appliances.
