Not sure if I am reading it correctly. But what ip adress is your given to your pc?
It reads to me like you have router 1 and 2 on router 1’s network but your pc is on router 2’s “internal” network… which must not be in the same 192.168.1.x range as is router 1’s network.
Put router 1 under 192.168.2.x range Then Then Router 2 with 192.168.1.x adressing should work still, and the pc should be able to talk to the router-1 network.
