Hello, I am suppose to have a decent internet connection, but the last two days my upload has dropped and my connection speed is all over the place.. When it's stable it's around 25 mbps down 4 mbps up but lately it's been The download rate jumps to being higher than usual or even lower than my desired rate and the upload is consistently slow.. When I watch streams they are very choppy and freeze all the time.. I called my ISP and they said there are no problems on their end.. What is the deal here???
