I have an Airport Extreme as my main router. I then have an older generation (wall wart) Express I use as a range extender. Problem is, certain areas of my house still don't get a signal. Questions: 1. Any reason to believe that the newest Express would extend the range further than the previous one if I replace it? 2. What's the best way to extend the range further to the parts of my house that aren't getting signal? As I understand it, if I add another Express (a second one) to my network it will degrade the speed/performance of the network, right? Are there other solutions? (I've been reading about "homeplug". Does anyone use that along with an Extreme?) Thanks, and sorry for my ignorance. The more I read about networking the more confused I get.
