While watching videos on YouTube and on other sites, my video randomly starts loading for a couple of minutes and then starts playing again. Now I've been trying to fix this for a few days and I even did a fresh install of Win10 1903. Nothing helped. The one thing I forgot to try is to restart my ISP provided Modem and my router. After restarting my router the problem was fixed for the rest of the night but this morning it came back. The modem that my ISP gave me is Technicolor CGA2121 and the router I bought is TP-LINK Archer C6. What could be the issues here?
