Question: I have my basement fully wired with RJ-45. There are no hardware faults with cables, the switch, router or NICs. The basement all connects to the switch. I then have the switch connected to my router upstairs (in another wall outlet). Computers in the basement can connect to the internet, but computers upstairs (using the wall outlet, which connects to the switch) cannot. The test netbook attempting to connect to the internet (or attempting to ping) has the following settings: IP address: 192.168.1.5 (No conflicts) Subnet: 255.255.255.0 Default Gateway: 192.168.1.1 (This is the router) DNS: (Using OpenDNS) I've used all Cat5e using the RJ61 Method for all the cables (Though, using Wikipedia to look this up it seems as though I shouldn't have!). Regardless, it works. Originally, I was using a static IP. Attempting to use the DHCP server (router) fails (no connectivity). Both wall jacks in use work--I've used them for the cable between the router and switch and have still gotten internet downstairs. Both the router and switch have auto sensing ports. I've tried both the first and last jacks in the switch to connect to the router. The link lights on the NIC and Switch work. There's supposedly even traffic according to the switch. Switch: SMC_1016DT Router: F6D4230-4 (and is up to date) I CANNOT communicate to the router from upstairs. I can from downstairs.
