Intermittent slow broadband access

I have M500 broadband package with a HUB3.0 modem/router. Been having very variable response times from internet access with web pages sometimes timing out. Using OOKLA Speedtest upload speed is fine at 500Mbps but download is a bit variable between 20Mbps and the normal 50Mbps. Looking at the hub stats for uplink I am getting the following having done a reboot about 30 minutes ago:

16QAM looks wrong to me. Should it be 64QAM? Might this be the problem. Virgin customer support wanted me to do a reset to factory defaults, but I am reluctant to do this because it will change the WiFi passwords which would mean resetting lots of remote devices like light bulbs and Solar PV inverter.

Any suggestions?

    64 is "normal" for upstream qam - not 16

    A VM person should comment on here
