How to extend WiFi coverage with Huawei B525 on the plot (building diagram)?

I enclose the diagram of the plot and I'm explaining what's going on.
The gray rectangle is where the Huaweia B525 LTE router is located. Individual colors depict descending range and so dark green is 3/3 dashes, lime 2/3, yellow 1/3, orange 0 or sometimes one, red lack of total. At the maximum range I reach about 25mb, with a weaker range, there is a terrible deterioration in speed, so I would like to strengthen it.
I care about the very good range in room number 5 and in the blue area (wooden gazebo). If possible also in the area of red lines in the yard (maybe some second AP in room number 6?) . In the area of the whole building, I can connect the routers with twisted-pair cables, they do not have to connect to WiFi (this will eliminate any further possible speed losses).

The building has about 60m2, the whole plot of 1500m2 - I know that the scale does not match.
What to buy and in which room to assemble? It is supposed to be the internet only on the plot, so I do not care about configurability, options, firewalls, only stability, speed, range is involved. PLC is gone, so please do not offer.
As for the price, it would be nice if it was in the range of about 200-3 PLN 00 for one AC.

Possible solutions are:

- moving the router to room 5 or room 4 and checking the functioning,

- replace the router with a model with external antennas, and not like with an internal WLAN antenna now,

- third option:

It is difficult to accurately refer to the subject because you have not provided significant data, which is the size of individual rooms, the type of building structure (reinforced concrete, aerated concrete, brick, composite foam plate + sheet, have an impact on the spread of the electromagnetic field.
Instead of asking yourself to make a sketch, it was enough to give the above data and the distances you are interested in outside, including the distance of the wooden gazebo.

If you want to reach the area of 1500m2 plot (for example, 25mx 60m), I suspect that it is necessary to place antennas outside the building.

In most cases, with an external antenna installation, a very good result can be achieved up to 50-80 m, depending on the technical conditions in a given location.

One solution might be to place the router in the window opening.

The point is that the LTE router must stand where it stands today. I have rigidly attached two 1.8-meter directional antennas to the LTE (ATK-20), which must be directed gently towards the south-west, which is impossible on the eastern wall, i.e. near room 5. ...
There is also no option to replace the current LTE router with another one, that it will probably not help much about the same range outside, and two that the B525 itself cost almost 600 zlotys and I feel a pity for it, especially that it works really well and is a real plug and play device .

The visual image was waved because I do not know the dimensions of the rooms. It is an old building in the countryside, probably a brick, and a roof with eternit. If it would be helpful, during the weekend when I will be there, I will measure the exact dimensions of each room, as well as the distance of the gazebo (its dimensions are 6x4 m), and then I will write here.

Such antennas outside that you mention - what is the cost and how technically should you take it? I do not conceal that it would be great to have the maximum coverage on the whole plot and not to play in adding individual ACs .

External antennas can be used buy at different prices, depending on purpose and performance.

You can also have such an antenna do it yourself .

The only question is why the author has to do such "antennas"? The subject is evolving in a funny direction, so it's time for professional advice. First of all, under B525, you will not hook up such antennas. Secondly, you need to distinguish WiFi coverage at home and its improvement from outside coverage. I suggest starting with extending it in the house using PLC adapters on the mains. For this purpose, you will buy a set of two D-Link DHP-W311AV PLC transmitters for around PLN 100 for around PLN 100. You connect the first to the socket at B525 and connect the LAN to the B525, the second in the last room, the latter has a built-in AP WiFi and extend your coverage to this part of the house and possibly the range will also be in the gazebo and some part of the garden. You will take measurements and find out. For measurements use an Android phone and WiFi Analyzer, it shows the signal parameters in dBi, the signal at the level of -70dBi provides a stable connection. If you want to cover the entire plot with WiFi, it is best to use an external access point, for example: Ubiquiti PicoStation M2 HP Used / new buy on allegro for 250 PLN. If you do not care about the omnidirectional characteristics, you can use CPE, for example Nanostation LOCO M2 . It has directional characteristics. Each of them will connect via LAN to the B525 or this transmitter with WiFi in room 5. Start with the extension of WiFi transmitters, do the tests.

But buddy, you join the conversation for the first time reading the last two posts superficially. As if reading a colleague, he will understand that we are talking not about your device, but about devices that are to be additionally bought.

And yet the author wrote clearly in post # 1:

If a colleague does not want a PLC, then it remains to buy a router, configure it as an AP, connect it via LAN to B525 and set it in the last room. Further procedure as with PLC. Cost for WR-841 and cable about PLN 70-80.
