Ok, update time! I factory reset the router and initially the speed was restored! However, it pretty much straight away vanished! So I split the channels and connected via each one. 5g was poor whereas 2.4g was close to normal speed, around 45meg compared to 53meg, so I am happy for now but hoping that a future update will reverse the change and allow me to only have one SSID. Thanks for your help on this. It was driving me mad!
So happy I found this. I had been away on holiday and when I came home my iPhone 6s was dreadful on Wi-fi. I have reset network settings three times over the last week and also done a factory restore twice. Works for a while and then reverts to everything being slow. Perfect on other Wi-fi networks.
It was only today that I noticed the firmware had been updated while I was on holiday. As a BT Plus customer I called them and the suggestion was to factory restart the Smart Hub and monitor for a day. I did mention that problems appeared to have started after the firmware update but they couldn’t help me on that.
I will call them again tomorrow armed saying I am not the only one having problems.
before phoning if you have reset the hub did you then turn off smart setup?
then did you split the networks to see if that helped your connection
Yes, first thing I did was turn off smart hub. Not a feature I have ever liked. I haven’t split the network yet but will try tomorrow as I had just done another full factory reset on phone and I’m done for today having spent so much time on it. Luckily, iPad working fine, but it’s not cellular so for somethings I have to use the phone. My data allowance was was being used up rapidly! Very annoying when I have super fast internet and have to revert to 4g.
Thank you for your assistance.
Thanks for highlighting this issue and welcome to the community. I am very sorry to read of your experience with the 5GHz wireless range and the speed you can achieve when connecting an iPhone.
We have highlighted your comments to our dedicated hub team for advice. They have confirmed that they have seen a few instances which match your description. It appears that this issue effects some older iPhone models (iPhone 6S and iPhone 7). The good news is that the hub team have also confirmed that switching your wireless mode to option 2 will alleviate the problem.
To change your wireless mode follow these instructions,
The team are investigating and will be working to get an update to the hubs. When I learn more I will be back here to share the information.
Once again I am very sorry for any inconvenience this is causing.

The split of the network has worked for me and has been stable for the last 5 days. Hopefully I will not have to do anything else before BT release another firmware with the fix included.
Should I have any more problems I will follow the solution as provided by @SeanD
Thank you all for your assistance.
Have you split the 2.4/5ghz networks as posted already
Thank you for everyone's suggestions and feedback.
Whilst this is being patched I have switched to Mode 2 and all seems to work well now.
Are there any drawbacks to being on Mode 2?
Smart Hub Modes:
Mode 1 = g/n and a/n/ac
Mode 2 = b/n/g and a/n
Mode 3= b/g and a
