I have an AirPort Extreme, and an Aiport Express set up to extend it. But I'm not sure if it's actually working that way, and am having a hard time making that determination. When I stand fairly close to the Express, I often see only two bars of signal strength. When I open up Airport utility on my phone, it says that the only client for the Express is a TIVO that is connected via Ethernet. All other wireless devices are listed as being connected to the base station. My thinking is that when I'm standing near the Express I should get a full 3 bars of wifi, and... well I'm not sure if Airport utility would show me connected to the Extreme or the Express. Is there an easy way to confirm what mode everything is working in?
