The GS305v3 is physically connected by cable to a LAN port on the router, where private RFC 1918 Addresses are issued by the DHCP server?
What typically cant work is an Ethernet connection to a ISP -modem- where one or a handful of public IP addresses are assigned to the clients on the LAN - these are intended to connect a NAT router only. Do the devices connected to the GS305v3 get warnings of no Internet connection? This would be a a clear indication a change in the cabling (in your office) from the network port on the wall to the router LAN port is required.

They connect perfectly if I plug them in directly to the LAN port in my bedroom. But if I connect my switch to the LAN port and a device to the switch, the device is not receiving any internet connection.

And yes, the LAN port is connected through cat6 from the router, that LAN port is connected to a LAN port in my bedroom via cat6 cable.
