I am getting the internet connection from my local area ISP. I want to use two routers on this connection: [Router 1] for general mobile device WiFi usage and [Router 2] solely for my PC for online gaming via Ethernet. My reasoning for this is that when I enable WiFi on [Router 2] it gives me high ping spikes while playing online games.
Would LAN-LAN or LAN-WAN be better between the two routers?
Will the internet usage on [Router 1] affect my latency on [Router 2] through which I will be playing online games?
Will the second router get its IP address dynamically just like the first router?
