Segment ip

I got a router. Its ip address is 192.168.0.254 with subnet mask 255.255.255.0.

All other workstation ip addresses must be 192.168.0.xxx.sm 255.255.255.0

I try to put their ip addresses to 192.168.1.xxx.sm 255.255.255.0 I cannot access to the internet.

Is there any solution for the workstation using ip address 192.168.1.xxx to share the internet access using the same router(ip 192.168.0.254)?
