My local Apple store has the older Airport Extreme (b/g) for $129 which I figure is a pretty good deal so I think I'm going to buy it. Questions: 1] Can I connect an iMac through an ethernet cable to the Airport Extreme (to have a wired connection), and then have my Macbook connect wirelessly to it? 2] Is it simple to set up? 3] Does it get good range? I'd need a strong signal around 100-150ft away, can this deliver? Or am I better off getting a Linksys WRT54G or some other router? I'm not very smart tech-wise so I'd like a router that will give me the least amount of trouble. Any personal experiences with the product would be appreciated.
