About 4 months ago I got a new MacBook PRO and connect via an airport network in our house. Recently our internet connection went down and I've been struggling to mooch off a neighbor's weak signal until we can get things fixed. About 3 weeks ago my wife got a new Macbook. While I was struggling to send a single email the other day, I realized she was still online and zooming around the web. I discovered the range of her airport card must be twice as mine. I can see about 8 networks, and she can see nearly 30! What's the discrepancy? Aren't all airport extreme cards alike? Have they been putting something fancy into the new macbooks?
