Just chiming in, I also started experiencing many of these symptoms about a year ago. Spent too much time trying to figure out why or how. There's no way to get rid of it best to just learn how to live with it. I like watching p*rn so the entity (person/persons) can tag along with me. Don't waste your money trying to buy new devices, etc. Best I got after new router, was a Mac book good for an hour before a partition was downloaded and installed- not able to remove, apple wasn't either they just gave me another laptop. I don't use it anymore collects dust. Good luck to you all, I'll be surprised if this posts.
