Spawn Meterpreter/Shell on Another Wireless Network?

Recently, I decided to test how good our home AV was. I created a msfpayload with a Meterpreter. I then first disabled the AV on one of the computers in the household to see if I could get a meterpreter session spawned. Then I turned on the AV and the .exe file was instantly quarantined and removed.

The computers were on the same wireless network. I am wonder how I would be able to get remote access of a different computer on a different network, as my classmate also wants to see if MalwareBytes is a good AV.
