your set up should be sonic drop > modem / router > switch > devices
Judging from your set up picture I see sonic drop > into switch > into devices ( I assume one of the devices is the actual router ) , therefore there is nothing assigning dhcp / IP addresses to the devices so they will not work .
Put a router in front of the switch and right after the drop so that the router can assign IP's to all devices plugged into the switch ( since the switch appears to be managed set it as a dumb switch to just forward traffic unless you need some specific settings on some ports / devices )
