I am in the market for a new wireless router. My old Airport Extreme just isn't cutting it anymore. We have always had range issues but are starting to experience frequent connectivity issues as well. So, I was hoping to get a recommendation on the best option for my situation. Here we go: I live in the upper unit of a two story duplex. We share the wireless network with our downstairs neighbors and even before the recent connectivity issues have had a lot of dead spots, both in the upper unit and downstairs. My original idea was to replace our current router with a new Airport Extreme upstairs and extend the network with an Airport Express somewhere else in the house to maximize our wifi coverage. My only worry with this plan is that the Airport Extreme has not been updated in quite some time. Would I be better off paying the same amount of money for a newer router from another brand(Netgear, Linksys)? Any advice would be greatly appreciated.
