I have a router and a switch together in a room, the switch connects to a patch cable witch connects the wall ports in others rooms. In another room I have only one port, but I want to get several connections in this room. Can I connect a cheap 4 port switch to this one port wall jach and then connect 4 computers in this room? Basically it would be kind of "daisy chaining" switches. Can this be done, and what are the problems with this if it can be done?
