difference between bridge and repeater?

I am attempting to bridge from LAN A to wireless and then bridging from
wireless to LAN B. Would this overall situation still be called bridging or
repeating? Ultimately, I want to go from machines on LAN B back to a router
on LAN A to get DHCP.
At our disposal, we have Orinoco AP-500's and D_Link 614+ routers. Both
have a transparent bridge mode. Is any of this hardware capable of such?
I did spend a bit of time trying to make it work with the Orinoco units.
Initially, everything was open: all protocols were to be bridged and no
MAC's were denied. Still no luck. Another assumption I made was that both
of the bridges should be on the same radio channel. Wireless NIC
connectivity was fine on whichever unit was connected to the Internet LAN
though jumping on a crossover cable out of the other bridge gave me nothing.
As far as the Orinoco's go, the documentation is pretty awful. The D-Link
is much better.
Any help or direction would be great.

Thanks,
Todd
