The following article explains two best ways to extend wifi to another building using wireless bridge and outdoor access points. The recommended ways can be used to extend internet to another building.
How to extend wifi to another building using Wireless Bridge
Wireless bridge is one of the recommended solution to extend wifi range to another building. A wireless bridge is a device that connects two separate networks wirelessly by building a point to point wireless link.
Building wireless bridge
To set this up, you need to have a clear line of sight between the buildings. A wireless bridge comes in pairs of two wireless access points.
The UeeVii 5.8G Outdoor CPE Point to Point Long Range Access is a good choice for a wireless point to point bridge.
It is a pair of two access points which is then configured to setup a point to point wireless link. The first access point is setup on the first building and the second access point on the other building to which the wifi signal has to be extended.

How to extend wifi to another building using Outdoor Wi-Fi Access Point
Outdoor wifi access point is another recommended solution to extend wifi range to another building. The outdoor access point is typically connected to the main network in the building 1 , which is then used to transmit the wifi signal to the second building. It is another recommended solution to extend wifi range to another building.
The WAVLINK AC1200 Outdoor Wireless High Power Weatherproof WiFi Long Range Extender/Access Point/Mesh is a good choice for outdoor access point.
Wireless bridge vs access point
A wireless bridge is ideal when you want to connect two networks which are in two different buildings. This acts like a leased line for connecting two offices.
In this case, a wireless link between two access points are established for establishing the leased line.
For this setup, a clear line of sight is required, without which it would be not possible to setup a point to point bridge.
An outdoor access point is ideal when you want to just extend your wifi coverage to another building in the vicinity. For example, this could be a nearby barn or a building with an open space where wifi from the main building has to be relayed.
An outdoor access point is not recommended when you need to connect two buildings.
A wireless bridge is a recommended choice if you need to connect two separate buildings wirelessly while an outdoor access point is recommended if wifi coverage has to be provided to a large area like a barn or parking space.
The type of product need to be selected based on the deployment environment.
