I live in a remote town on a small island in the Philippines. A guy in town has a satellite internet connection, which he broadcasts via wireless to the whole town. I have an external outdoor antenna pointed at his antenna. The cable from the antenna plugs into a PCI wifi card in my PC. My internet comes through my connection to the wireless network.
What I need is to plug the outdoor antenna into a hub/router/repeater/bridge that can connect to the wireless network as a client, then share that connection to my house, either via wireless or wired connection. The device needs to be smart enough to act as a client and connect to the wifi network and then like a cable modem, share that as the internet connection on my home network.
Is there a device that can do this? Please be specific! What device can do what I need?
