I have a connected a router (D-Link DIR-655) to a Sitecom 8-port Switch.
If I put all computer/printer cables into the switch and only one cable to connect the router with the switch, everything works well.
But if I put one of the computers/printers into the router, it seemed to be that a second network is created because there's no communication possible between computers that are connected to the router and computers that are connected to the switch.
How can I solve this?
PS. I have 3 PC's, 3 Mac's and 1 Network Laserprinter.
