Here is my question. I think this will work, but can i put an ethernet 'switch', like the TRENDnet TE100-S5 Unmanaged 10/100Mbps Fast Ethernet Switch, at the end of a LAN line that comes out of my wireless router ? I have a LAN line from the router going to the tv room, and I would like to plug all 3 devices in the tv room ( receiver, tv and dvd player) into a wired system instead of wireless. This switch would just split the one LAN line, correct? Would it mess with the router in the computer room? Thank you!
