I'm looking to expand my wireless network through the use of access points. Currently my setup is a modem that is connected to a SonicWall. Our apple express acts as our wireless router which is plugged into the SonicWall as well. We have many switches that go up through walls and floors. I was wondering if I can use an access point to expand the wireless say, on a completely different floor through the use of an ethernet. My only concern is since the ethernet isn't running directly to the Apple airport then it can't relay the wireless. Is there any solution to this?
