How best to monitor ISP speed & quality

Aug 17, 2018
I would like to automatically monitor my ISP internet speed & dropping frquency - ideally for a week or so - just leave my PC on, with software monitoring & collating the info in background. Is there an idiot proof bit of freeware. My ISP promises 76 Mbps (using ookla, I rarely get 50 Mbps) & dropping is frequent (but intermittent) at night when watching netflix!! Thanks
