Airport Extreme for local net, not Internet

[tlongacre]

I just got an Airport Extreme which I want to use to setup a local network in my house, to share a HDD and allow communication between iPhone and MacBook Air. Set up the wireless network, connected HDD, all seems okay.

Except for this --

I connect to the Internet via a USB-key which must be plugged into the MacBook Air. Whenever the wireless is turned ON, it blocks the USB key Internet connection.

There must be some way to do this -- so that Internet apps know to use the USB Key rather than the wireless network to connect. (On a PC I would know how to do this), but I cannot see how to do this on the Mac. Can someone tell me or point me where to find the answer?

Thanks.

What kind of USB key is it? A WiFi key? Why do you need to use it?

Something is wrong here, I have a similar setup but I can connect to my Dreambox connected with airport to a TP-Link and have my internet connection over a USB 3G Dongle, no problem at all.

Ahh 3G USB key. Turn internet sharing on in OSX, ignore AEBS.

Or get a WiFi router that supports your USB 3G.

Or turn your iPhone into a 3G to WiFi hotspot.

Or open network settings, and move the USB key to the top of the list.

I don't have my sharing on most of the time and it still works.

Yup, that's probably it, I have mine on top.

Thanks mates! Moving the USB key to the top of the list did the trick. I *knew* it had to be something stupid easy.
