Is it just speed fluctuation or do you get total drops too? If so, are the issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables? If you don't know, can you check to help diagnose whether it is just a wifi issue or it could be network connection related?
What are the various Hub lights showing/doing when this happens?
Also do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box.

I do not work for VM. My services: HD TV on VIP (+ Sky Sports & Movies & BT sport), x3 V6 boxes (1 wired 2 WiFi,) SH2 in modem mode with Airport Extreme Router +2 Airport Express's. On VIVID200, Talk Anytime Phone, x2 Mobile SIM only iPhones.
Just speed fluctuations, only evident on wifi connections afaik, Hub light stays white. I have also checked the connections and all are tight, and no evident kinks/faults in the cables.
From the table below it looks like the 2.4ghz is not running on the correct modes? 802.11n should be capable of higher speeds than that even with a number of devices...
Also worthy to note that M-iPhone and Desktop are both in the same room, as are K iPhone and iPad... so I don't think that it's any signal interference or external factors causing the speed difference.

You may find splitting the bands beneficial but you will need to connect to the WiFi on the best band for the device you are connecting. It can be a bit tricky having to try out a few things so a few tips:
Any devices closer to the Hub would be better placed on the 5Ghz band.
Any devices further away from the Hub would be better places on the 2.4Ghz band.
Any devices that can be wired into the Hub, should be.
To split the networks, just follow these steps:
Access your Hub by navigating to 192.168.0.1
Login with the default login info (on base of Hub) unless you've already updated it.
Go to Advanced Settings > Wireless > Security
Under Wireless Frequency 2.4GHz change the Wifi Network Name (SSID) and the Wifi password (network key).
Repeat for the Wireless Frequency 5GHz and click on Apply changes.*
*Make sure that both frequencies are named differently and are still identifiable
Replying as this may be useful for anyone seeing similar problems..
This afternoon the wifi-cards completely gave up, ie hard-wired devices could still connect to the hub but Wifi devices could not despite the SSID still being broadcasted. On call to support the agent said he could see a lot of congestion, so suggested the following fix:
We disabled channel optimisation and set the channels for both bands manually, channel 8 for 2.4ghz and 104 for 5ghz. We also did a push-button hard reset of the router beforehand. The support agent could see immediate improvements in the amount of congestion, and speeds/signal strength appear to be much better.
I wouldn't be surprised if the wifi-cards installed in these hubs are fairly low quality (compared to commercial grade APs such as Cisco/Xirrus)... but I guess that's the wonders of mass-market for you 🙃
