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?

To give your computer the priority on bandwidth, it should be connected to the first router.
The second router for WiFi should be connected to the first one by LAN-to-WAN, as this will make your computer an equal partner to the entire [Router 2] sub-network, so the computer will always be able to use at least 50% of the bandwidth for itself.
[Router 2] should also be a DHCP server, since its sub-network will be completely isolated from your computer.
If the first router supports Quality of service(QoS), it can be configured to give your computer the absolute priority when required - so during heavy gaming sessions your computer may use up to whatever bandwidth limit you have set (100% is likely too high so an 80% cap might be better).
