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?
