i have a speedtouch 585 adsl router, also have a switch upstairs with two pc's connected. the switch ip is 192.168.1.67, the two pc's have a default gateway pointing to the switch and static ip's and they network fine. i want to connect the router to the switch so the pc's upstairs have net access and also network with a wireless laptop. plugged the switch into the Ethernet port on the router and it does not see the switch. i have a feeling i have to disable dhcp on the router and assign static ip's ? any help appreciated.
