Hello,
I am wanting to get two wireless routers
One for my building and one for the other
I also want to get a wireless access point but I am confused about how it works

I want to ask if i buy two wireless routers, two antennas and an WAP will that connect the two to the internet located in my building ?

4 to 5 km is to big of a distance to connect two wireless routers even with directional antennas. The range of wireless is about 60 m.

If you have direct line of sight you could microwave dish setup. $$$$

Otherwise two internet connections and connect the two locations via VPN.
