I have a '07 MPB (2.4 w/4gig RAM) running Lion. I use an Airport Extreme base station for internet access and wireless printing or HD. This was fine but failed some time ago and I didn't bother to fix it since it wasn't hard to plug in one or the other when needed. Now that I have Lion installed I'd like to get it going again but have a problem. When I open Airport Utility it says: "AirPort utility unable to find any AirPort wireless devices." This is curious since I'm using the airport to get online. I've tried moving the laptop to within 1' of the station just incase it needed a very strong signal but it made no difference. Any ideas?
