I'm looking for a new wireless router for my home. Range: In my home (just 1100 sq.ft totally), there are 5 rooms (including living room) all on the same floor, separated by brick walls. The router should be installed in one room that is in one corner of the home. Devices: My brother and I each have iPhone, iPod, iPod touch and MBP. If you count other wireless devices, there will be like 11 devices totally at my home. And all of those devices are on different rooms. There is one desktop computer and printer which can connect to the router via ethernet. Which Apple router should I buy? Airport Express or Airport Extreme? Since both offer simultaneous dual band capability, I really don't know which one to choose. I need a very good range and speed all throughout my home, no matter which device I use to connect to the internet. Pleae advise.
