A lot of time when downloading movies/games/apps I noticed that the speed at which the files download gets lower , usually by a couple Kb/s , until it halves or worse. For example , when I started a download recently everything was nice and good , about 800Kb/s , even let the thing download overnight to make sure it finishes before I finish my business. The next morning I see it still downloading, with ~300 Kb/s. I noticed this mostly on browser downloads. Does it vary from one browser to another? I am using Microsoft Edge at the moment. I also noticed that if I reboot the router / unplug the cable it goes back to the original speed.
