Internet D/Cs

Have had problems since starting my service 3 months ago. It's always the same thing over and over. Missing Required Option 82 and Option 24. Causes spontaneous disconnects for 15 seconds or 5 minutes, it always changes. I have had a tech out twice to find a problem. The wiring is fine. It passes all tests the tech could do. It's all new. All splitters are removed. The connector in the internet box is completely new as well. I am at my wits end with this issue. Wifi or ethernet doesn't matter. It's annoying when gaming, or trying to watch movies, but im not paying all this money for constant disconnects.
