We have one PC (IP: 192.168.0.1/24) to connecting the switch and WIFI AP, then our Samsung tablet (IP: 192.168.0.2/24) which installed THREE apps (QS, Host, Teamviewer) on it, and do a ping for both successfully. Be reminded there is NO internet access network.
On PC, we changed the option setting “incoming LAN connections” to “Accept” and re-launched the application. But it can’t to connect to tablet device by IP address based.
On tablet device, I can to connect to PC by IP address successfully without any settings changed.
