For Shoot Pro you will need to have a router in line with your computers. We suggest a TL-WR940N by TP-Link. You will need to also ensure that your firewall will allow port 12010. As well as all of the network profiles set to private. This will allow for shoot pro to communicate.
If you do not meet these requirements, please purchase the components needed and have someone who is familiar with IT set up the system for you. We are not general IT support, so please only call in if the issue is with 3S, not your network
