There are so many different types of wireless routers. My understanding is that wireless n is faster and stronger than wireless g, but I have read comments in the experts exchange database where members using wireless n have had bad results, especially if there is no direct line of sight between the computer and the router. I will be using the router for computers on 2 different floors. I understand the theoretical benefit to a dual band router, but is it really any better in practice. What is wireless n+ & would it require modification to a computer to use it if the computer already can use wireless n? Finally, there are a lot of different models of router from the same manufacturer. What should I be looking for in deciding what to buy (including issues with firewalls)? I know that in most cases, just because something is higher priced doesn't mean it is any better and that manufacturers often overstate things like speed. I also don't want to pay for more features than I need. If anyone has recommendations on particular hardware that they use, I would appreciate it. Thanks for your input.
