Beginner issues with home lab

Hey all,

I'm looking to set up a home lab to get better with networking. My ISP at home is FiOS and I was able to take home from work an old Cisco 891F ISR. I've reset the cisco router and am using it essentially with default settings. Here is a picture of my current setup: https://imgur.com/a/Vmk0BMu

The issue I am having is some connectivity issues between the networks. I am assuming there is a routing problem but I'm not sure how to fix it. All hosts have internet access as I added ip route 0.0.0.0 0.0.0.0 192.168.1.1 to the Cisco router.

PC1 can ping 192.168.1.3, but not 10.1.1.1 or the server IP. Server1 can ping 192.168.1.1 but not the PC1 IP.

I also tried to add route 10.1.1.0 255.255.255.0 192.168.1.3 to the fios router, but that didn't seem to give me anything either.

Any help would be much appreciated. Thanks guys!
