I am having difficulty maintaining a consistent internet connection with too many black spots around the property.
The current setup is as follows:
1st floor: WIFI Router (DSL) with wired connected to WIFI extender (plugged into power outlet) which sends signal to second floor. One other WIFI extender on 1st floor to improve wifi coverage. All are bare bones TP-Link products
2nd floor: Wifi Extender to receive signal from first floor and two other wifi extenders.
Each floor is roughly 100sq.m or 1000 sq ft. Each floor is a separate unit. The walls within each unit and the exterior walls are very, very thick concrete.
On the second floor especially I only get a clear signal from the WIFI extender near the main entrance whose purpose is to get the internet connection from the first floor. This signal serves only one room, the main entrance. The rest of the unit has so many black spots and connection stoppages even within a few feet of the extenders.
Outside I don't even have a signal within one foot of the entrances. This occurs on the first floor as well.
Question: I am looking for products/solutions that cost under 400$ total that will give me a clear signal in each room on both floors and give me an outside signal within say 10 meters of the entrances on each floor., despite the buildings heavy concrete walls and remote location. My internet connection is roughly 15 mpbs down and 1 up.
For an additional cost I wanted something that I could use outside to give me an internet connection with 200m of the exterior of the building. currently my outside wifi signal is roughly 100m, but I have no internet connection past 20m.
Any suggestions as to what i need to get what I want done would be great.
