I'm in a situation where I have only a wireless connection to the internet that can only be used by one device at a time. What I would like to do is connect my Macbook, then share this connection by ethernet to an Airport Express. Then I need to have the AE send a wireless signal that I can connect to with other devices, i.e. iPad and iPhone. The goal is to be able to use this connection on multiple devices at the same time. So far I've accomplished sharing the connection on the Mac (internet sharing through Thunderbolt ethernet), but I'm not sure how to configure the AE (old style) to send out a wireless signal. To clarify, I can see the AE from all devices and connect, but I'm not getting internet access and not getting a green light on the AE.
