I have been on 200Mbps presentation for over a year. I now do a daily speedtest and have an average speed of 80Mbps. Tested just now and am getting 34Mbps. Oh, I get occasional drop off as well. Over the last year I have made numerous calls to tec support who have me turning things off and on and generally running around the house. I have had numerous visits from engineers who start by doing a speed test and get a result of over 200Mbps and look at me as if I am a fool. I tell then that the fault is intermittent but I generally get the lower reading. I do a test on my phone and get a read of 70Mbps to 80Mbps typically. They then tell me that my phone is old or the software is not up to date, so I ask them to test with their own phone and guess what, they get a reading of between 70Mbps and 80Mbps. They then test again with the Virgin phone and get the lower reading. Then we go through the process of testing equipment, blaming my "old" equipment checking the "box" at the top of the street testing until they get a read of over 200Mbps and then tell me it is fixed. Whilst we are completing the paperwork I run a speed test and guess what, I get the lower reading. The next step is that they report to a supervisor. Then I get another visit. There is no way that I will do as you have done and get details from the hub myself, first I am not technical enough and second I pay £1500 a year for a service. Now I am fed up. If I could find an alternative supplier I would move.
Sorry to hear you're still having these issues.The BQM graph you posted looks great and everything looks healthy on the hub side of things. Can you try connecting your PC directly to the hub in modem mode and let us know what speed test result you get?
