Sysadmin student with Networking problem.

Hello! I just want some enlightenment and knowledge with networking. We are given 1 switch (netgear) 1 router (realtek) both with 4 ports. We need to have 4 different sites under 4 different subnets. And so we have configure our switch with 4 diff subnets E.g: 192.168.0.10 192.168.32.11 192.168.65.12

Our problem is we cannot ping computers. Because we do not know how to setup/point out our addresses.

I hope I made sense....
