Ok, so consider this: Basically, I've got a 4 port modem/router and I'll eventually run out of ports, so I'm assuming I can simply connect something like this to my router in order to add ports. Will the router still assign addresses to devices connected to the switch? How does that work? Does the switch itself get an IP address? Do switches normally have web interfaces, assign addresses, etc, etc, like a router? I is noob. And what about the wireless clients? Would they be on the same subnet as the wired ones? I did some googling but am still confused.
