I just bought a SF1005D desktop switch. I have home ethernet/DSL connecting to my desktop PC ,and I wanted to share the internet connection between my PC and my Samsung Galaxy S9. My DSL is connected from my router to Port 5, and I've connected both my Galaxy S9 and desktop through two of the remaining ports.I have green flashing lights and everything's plugged in. The problem is, I can only access the internet on one device at a time. To use the other, I need to physically unplug the other device, and replug in the router cable to Port 5. Do I have the wrong device for sharing DSL internet between devices?
