Remote access

Good evening. I installed the LiteManager program to manage remote access of computers .. There is a video with a complete overview, I installed, all the rules, the lan network .. But as soon as I connected the wireless adapter (Wi-Fi Internet) to the main laptop, the connection was lost. I so understand that there was a conflict of networks. (On the second laptop there is another Wi-Fi network for the Internet)
