I have been looking on Tigerdirect for some of these adapters but still have some questions after looking at them. None of them say anything about using multipule adapters. My router and switch is in the basement but I have 2 additional bedrooms on a second floor (of a newly built house) and I don't want to run wires up the siding. Do any of these items allow for one piece to go into the basement with the router then one adapter to go into each upstairs bedroom? What seems to be the better brand? I have a Linksys router but a D-Link 24 port switch.
