I bought the new airport extreme to extend the wifi range in my household and hoped to share a hdd. Upon my experience and reading the forums, the sharing hdd is not as easy as I thought. But that is not my issue at the moment. My issue is with extending the network. A couple weeks of ago, I did the setup to connect the two airport extremes together (older round AE & new box AE) using aiport utility. It seemed to have work because the signal was stronger in a part of the house that usually had 0 to 1 bar. But shortly after, the signal showed itself as inconsistent. The signal strenght is jumpy from 0 to full bars. And right now, I am sitting in a part of the house that used to have 0 bars and now, I get full bars. And yet my mbp cannot see the newer, closer in distance AE. What's going on here?
