    I currently am connecting my iMac to my wireless network through an external USB wifi adapter and it is working great. I tried just using the iMac's internal wifi, but I wasn't able to reliably make a connection. My router would register between 14% and 18% signal strength from the internal antenna, which apparently wasn't enough. With this big external antenna I bought on newegg, I am able to average around 35% signal strength to the router and my connection is fast and 100% reliable.

    The thing is, I have other wireless devices in this room that could use a signal boost. My PS3 can't make a reliable connection to the router either, and my iPhone is only a little better.

    So now that I'm using an external wifi adapter to communicate with my primary wireless router, is there a way that I can use the internal wifi function of my iMac AND/OR my iMac's ethernet port to share the good connection with other devices in the room?

    I suppose that USB WiFi adapter doesn't show up in System Preferences > Sharing >> Internet Sharing >>> Share your connection from?

    That works perfectly on the iPhone, but the PS3 can't even pick up an IP address. Any idea on how I might be able to manually configure the PS3 as far as the DHCP host, DNS settings, default router, etc, for better results? Does the network created out of Internet Sharing work as an "ad-hoc" network?
