Internet slows down to a crawl every few hours.

[Maddys Son]

Every few hours my internet either speeds up, or slows to a crawl. Everytime it slows down i get the 10th of the speed im supposed to get. I normally get 20Mb/ps (Bits) download speed. Any kind of help is appreciated.

Also i already tried turning it on and off. k ? ok bye
