thanks shmokes, that helps. Like I said, I wasn't sure i was using the correct term for what it was i was trying to achieve. some of the info i found was, and others was not. wasn't sure.
seems like the actual bridging of a network is like you say, extending the wireless network. the ethernet bridge... the "bridge" part is kind of a misnomer that is really throwing things off.
alright, now that i know what i'm looking for, i can try and get things squared away.
First things first, i'm thinking i'm going to need to find a router I can install a custom firmware on to get the ethernet bridge i'm looking for.
