Hi there. My family is moving house in a few weeks and I'm thinking about the proposed network set-up for our new house. We have 3 imacs, a MBP, and 2 dell's. (not that any of that info is worth anything...). At the moment I just have thhe older AE (g, version), connected to our modem, which provides wireless to all the computers. Our new house is two stories high, instead of our current one. I'm wondering how the single AE is going to cope, having to broadcast to 2 levels. I would assume that placing the AE on the ground floor would provide better coverage? Since 2 out of the 3 imacs will be in this level? Also, I was considering purchasing another AE. Since you can't run the AE in both PreN and g, modes simultaneously, I should just get the AEg at a cheaper price? Main main concern is, will the AE work on both levels and if not, if another AE will suffice. People who live in 2 story houses and have AE's, please let me know!
