Good afternoon.
Need to connect 2 buildings via Wi-Fi hotspot. At the same time, in order to be able to see all the computers of one and the second building on the network. MikroTik access points are installed on the roof of the first and second buildings. The access point on the first building is connected to a switch. The second access point on the second building is also connected to the switch. So, how to properly configure both access points so that both buildings are on the same network, can exchange files and have access to the Internet?

Depending on the manufacturer, this may be called differently, but more often it is bridge mode - such as "bridge mode".
The result is almost, almost as if they threw a straight wire.

1. Both points must be on the same subnet.
2. Computers from one range of addresses.
3. Set up a Wi-Fi bridge, because as a matter of fact it is a wireless cable between switches.
4. The points must be directed towards each other.
4.5 Raise the link and ping the equipment.
5. The rest is trite and there are a lot of specialists-psychics according to the Mikrotik model.

1) Check the connection between the points by connecting a laptop from both sides and check how much pings die when transferring files from one computer to another (for example, using FTP). If the connection is ok, we move on.
2) We connect the points to switches (unmanaged?) and get a common network. The main thing here is that there should not be 2 dhcp servers or give them different address ranges. And, of course, the subnets must be the same, or you need to register routes on the gateway.

Use a radio bridge (directional antenna) such as Ubiquiti airFiber 5G34-S45. Works over very long distances, we use to transfer data over 7 km., for example, between points.

Thanks everyone for the response.
The situation is the following. At the moment, 2 access points have already been installed on two roofs of buildings. Both look at each other, trees, visors, walls do not interfere with them - the space is empty.
1. There is a Switch to which all computers are connected, including an access point installed on the roof in building No. 1.
2. There is 1 PC to which a 4G modem is connected. This PC is the source of Internet distribution over the local network to all other computers. Kerio Control is also installed on it.
3. The local network IP is set manually, DHCP is not raised anywhere. As far as I know, this is not a very good option. Therefore, if anyone has any ideas for improvement, I will listen carefully. LAN IP 192.168.0.XXX
4. IP address of the access point of the first building and the second 192.168.88.XXX. As you can see, the IPs are different. If on one of the local computers we change the IP to 192.168.88.XXX, then the access points are pinged, but if we return the IP of the local PC to the previous 192.168.0.XXX, then nothing is pinged.
I will attach a diagram, it is very similar to my situation, only instead of a modem I have a switch and only access points are connected via WI-FI.

rumaru please write what specific access points do you have?
The link between them is raised or the bridge has not yet been made.
If there is a link, then raise the EoIP tunnel on Mikrotiks (you can create it in the Interface tab) and you will have a seamless flat network between points. The main thing is that the ips do not intersect within the network.

Mikrotik sxt2lite in bridge mode, we scatter the network over a distance of about 100 meters. The quality is excellent. The price is great too.
