A:Answer Yes - that's what the switch is for. You plug all your network devices into the switch and the switch allows traffic to flow between the different devices. In order to reach the Internet, you have to have one of the connections go thru your cable router at some point, whether it's thru that switch, thru the wireless router, or another switch, or via a shared computer's network cards (which in essence is acting as a switch). I have cable internet (DSL is same connections after the router) and cable comes into my cable modem and out of it into my wireless router and out of my wireless router I have hard wired connection to my two switches and two hard wired computers. The switches hook up to several other computers/devices (Playstation/Wii/xbox/blurays/etc) and wireless gets all the wireless devices. I've noticed no interference hooking up with the switches. The only issue you might experience would be on your ISP side - ie. if you don't have enough throughput coming into/out of your house. ie. DSL is slower than cable. If you have 20Mbps or higher you shouldn't experience any lags (if you're not overburden with internet devices that is). But under 20Mbps (ie. most DSL) then you might if you have a lot of devices. But the switch won't be the issue unless it's defective.
