<p dir="ltr">I had "the exact " same issue years ago. After a half a dozen techs not being able to figure it out, a smarter tech brought enough equipment to measure everything in my house. It turned out that it was poor quality cable used for it.<br>
The signal strength was optimum arriving at the cable box outside the house but dropped big time at the room the modern was at.<br>
The tech put a booster for the cable TV AND ran a single cable from outside straight to my office. The problem was solved then.</p>

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
