I was having huge problems with latency via Virgin and my Nighthawk Router.
I purchased a fixed cable and was still struggling and was on the verge of buying a new router but I did a search on the web and there was advice to turn off ip6 and also turn off Upnp.
Seemingly all my speeds have gone through the roof and in 10 plus fifa games now I've had no issues at all. Not even a slight lag.
Speed results even from a wifi connection have also doubled.
My download speed on 22/10/2019 15:20 was 81.23 Mb/s and upload speed was 14.99 Mb/s through the wi-fi connection. My wi-fi speed was 679.91 Mb/s

What do you mean by fixed cable?
Is the nighthawk connected to superhub in modem mode?
I'm at wits end with mine!
15m ethernet cable but that didn't help.
Modem mode for super hub.
