Count the packet hops.
PC and router = 1 request and 1 reply.
PC, repeater = 1 PC request to repeater, 1 repeater to router, 1 router to repeater and 1 repeater to PC.
Maybe now you see why I use Routers as a WAP over repeaters.
BRIDGES are a different case. I'd need more detail to count the packets.
I have an old metal-walled mobile home that I plan on converting to a combination shop and man-cave; it's about 200 feet from my home's computer room, where I have a Netgear WNDR3400 wireless-n router. The only place in the trailer where I can "see" my home network is the kitchen window, and I thought about putting a Wi-Fi repeater there to extend the home network into the trailer. But I have read that using a repeater will cut the network's Wi-Fi throughput in half -- which would not please my wife and daughters back at the house. Is there a simple, relatively inexpensive way to extend the network to the trailer without slowing everything down?
Eventually I may have Charter install a separate cable hookup there, which would allow a separate high-speed Internet connection too. For now, I just want to "share" Wi-Fi to the trailer ... and keep peace in the house.
