Every night my upload is slightly over 4 mbps. Sometimes like 3.8, but still... nearish 4. 3 times a week I stream videos at 3 mbps upload speed. 1 day a week it works fabulous, 1 day a week it works meh, and the other day I can barely get passed 1 mb going up by the second despite my speedtest.net reading being 4. How is this possible and who do I talk to to fix it?
