General network routing question

[ocpaul20]

I hope someone can help with this problem please?

Both router A & B are Chinese and menu is in Chinese so I have to wing it with setting it up as best I can.
I can get onto them to the setup, and I can use the context to understand what I have to put where (sort-of) !
However, if I understood how to, I should be able to change my routing table on each PC to navigate and send files from one PC to another attached across the apartment.

Problem:

ISP router A
------------
I have an ISP router A (192.168.1.1) attached to another wifi router B (192.168.1.7)
I have a PC1 statically attached to router A (192.168.1.25)

Router B
---------
Router B allocates IP addresses in the range 192.168.0.100 onwards
I have a PC2 statically attached (192.168.0.111) to router B
I can reach the internet from PC2 without problems

How do I set up the routing tables to get from PC to PC please?
192.168.0.111 <---> 192.168.1.25

Thanks for any help on this one.

From PC2, run the command: ping 192.168.1.25

Do you get a reply?

What are you trying to do between the PCs?

When I ping 192.168.1.25 it does not return so I have to ^C
When I ping 192.168.1.1 it returns immediately with a normal ping return. (<1ms)

I just want ping to work between them, so that I can copy files(scp), telnet, putty, anything really between the two PCs.

Mainly I want to understand how to do it so that I can route traffic through routers in the future.
