OK, I've been at this for about 4 hours now. The end goal should look like this:

Router 1 can't be changed. Router 2 can be. The problem I keep having is that devices hooked up to Router 2 can't connect to the internet. Assume Router 1 doesn't have NAT. Is this possible or am I gonna have to do something else to accomplish this? I apologize for my lack of knowledge. The whole purpose of this is security by LAN isolation.
 
Solution
Those configuration screens are from router2. Right?
The config obviously is wrong.

WAN interface should be connected to router1. Address 192.168.0.2,gw 192.168.0.1 (or you can put in automatic address assignment).
LAN interface should be connected to 192.168.1 subnet. Address 192.168.1.1, gw - empty, dhcp enabled.
If router1 was a actual "ROUTER" is would just work. That is the function of a router to transfer data between subnets.

Your problem is the device you are calling a router is likely a consumer internet gateway. Its only purpose is to convert 1 lan subnet to a shared single wan internet IP.

The only way you are are going to get this to even partially work is to run NAT on "router2". The NAT will of course cause some issue with device on the main network access devices behind the second router.
 
Ok - 1st - disable IPv6 on "Wireless LAN adapter Wi-Fi".
2nd - you should use only one connection - either ethernet or wifi (not both at the same time).

3rd - what are both ip addresses of router2 ?
One is 192.168.1.99 (your picture has wrong address btw). What's the other one from 192.168.0 subnet?
Can you ping router1 from router2 web interface (ping 192.168.0.1) ?

4th - how exactly are rourer1 and router2 connected?

When I need access to the internet, I turn WiFi on. When I'm trying to work on Router 2, I turn WiFi off.


it's 192.168.1.99 right now because I just reset it. I haven't had the chance to set it to 192.168.1.1. As for the second IP, I want to set it to 192.168.0.2. I tried setting that on LAN and the 192.168.1.1 on WAN, and when it didn't work I switched it. Tried creating a bridge between the two as well. No matter what I couldn't seem to get devices connected to it. When I get home, I'll try pinging it.


Router 1's single port goes into a 10 port switch, then into a 5 port switch, then into the single port on Router 2.
