EAP225 Outdoor coverage
Hello,
I have some issues with EAP225 Outdoor. Let me introduce the configuration I have. On the below "diagram" I have tried to sketch how the AP is currently positioned. I have main building on the left which is elevated 2-3 meters above the other one on the right. AP is positioned on a 2 meter pole on the roof of the secondary in order to compensate the elevation from the other building. Idea of this "design" was to use only one AP and to cover the main building and the yard where I have some IoT devices for the irrigation. In the yard and outside the main building and iniside the one on the right I have no problems, but inside the main building on the left the signal is very poor. It is old wooden house with no or minimal metal inside... also only few electric sockets and lights... 
Questions are: Am I doing it wrong? Should I consider using directional AP, something like EAP650 D120-Outdoor? Maybe that way the devices in the yard will not be covered as they are on the ground and the directional beam will not be appropriate? Should I consider puting second AP inside the main house? What you will recommend?
Thank you in advance!
