Connect one computer to an existing network.
I could do this by adding an internal card but I had rather not get in to
those configuration issues.
Whit I would like to do is use the bridge/router to connect to the existing
wireless network and then pipe the ethernet DSL into the computer by the RJ??
normal eathernet port. By doing it that way I will not have to reconfigure if
I hardwire the computer in the future.
Also I do not want the bridge/router to act as a router in the correct usage
of the word meaning straight in by antenna straight out by one wire. Nor do I
desire for this device to act as a fire wall. All I need is a simple
transceiver to receive and sent which is connected to the computer by means
of eathernet.
