Hello everyone. The church I go to wants to implement wifi and I'm not sure whether use g or n routers. A little info for you:

The church has a pretty large square footage (I don't know how much) so more than one router will be needed to cover the entire building.
They already have a wired infrastructure so no problems there.

Picture a long rectangular building. On one end of the building are the administrative offices. Right next to those is the chapel, and then on the other side of the chapel is a large gym. Initially we just want to have wifi on the end of the building with the administrative offices, but they'd also like the signal to reach into the chapel and into a specific room next to the chapel as well.

What I'm wondering is if the n technology is supposed to push the signal further out than the g technology, possibly making it more accessible to devices from a greater distance. I'm honestly thinking that we may need to use some sort of external antenna or repeater or something. This is where I get lost and need your help. Any thoughts?
