Broadband keeps dropping the connection

I've asked the forum before but didn't get a response , my 512mb broadband keeps dropping tue connection not only with WiFi but with my hard wired pc also

im monitoring my connection VM say there are no issues on the app but the BQM shows differently https://www.thinkbroadband.com/broadband/monitoring/quality/share/5603f7170a8b2d323fe1fff007e9e09c4c4d43d3
