I have recently purchased four TP-Link CPE210 routers to connect to my home and two other houses about a mile straight from my mother's home with FTTH internet service.

Unusually, there was a hill between my mother's house and my house approximately 150 feet or 45 meters high (that mountain has a 220 Volt power line), and there was a tree between that hill and my mother's house.

I want to know what to do. Need to buy something other than CPE210?

What else do I need to control the speed in my house and two other houses and control the Wifi sharing in other phones?

My WiFi man and his parents have a Covid-19 infection. But I hope you will give me some advice as soon as possible, because if I do not put it into practice I will lose a lot of my reputation.

I believe I can do it if I have specific guidelines.

But I will succeed only if you give me advices and guidances.

Please seriously give me the idea to
