It would help us help you if you give us a little more information. What type of equipment you are using such as Windows, Apple Mac, or an Android phone or iPhone or tablet.
What internet product are you on from which provider? The problem may just be the way they work.
What router do you have. Some cannot provide the information for BQM, but most give at least basic connection data. The method of getting the data or letting it create a BQM graph varies by manufacturer and sometimes also your ISP.
Connections: OnePlus 8 Pro on Three 4+ (LTE)/5G and at home Three Mobile, with (Three)ZTE MF286D router giving about 113/20Mbps.
