Just got the Deeper Connect Mini and got it working with my Windows PC.
The setup like the following
Internet RJ45 socket >> Router Wan Port Router
Router LAN port to Deeper Connect Mini port 1
Deeper connect port 2 connect to a network hub.
One PC and One Macbook connect to the same network hub on LAN port.
The PC windows can go to Internet while the Macbook can't.
Macbook can't even ping the Router LAN port 192.168.1.1, but the PC can ping just fine and they are on the same network hub.
So, it seems like there is some compatibility issue with MacOS and DeeperConnect. Please help if any firmware available for a fix.
