The Hub is Hub 3. Devices are connected in 2.4 and 5. I've tried to manage the devices which are on 5 to allow my laptop to have the faster speed but that has not been necessary as many of the devices are defaulting to 2.4.
It is WIFI predominantly for my laptop Mac air and iPhone XS. Other devices are connected directly with the exception of my sonos and 2 alexa's.
It's really odd I am getting 20-30 MB some days and then 70 on others so not consistently 30 days but not the best all the same.
Thank you for your post RLTon and welcome to our community.
Have you been able to run a speed test on one of your wired connections? If so could you please let us know the results of these compared to the WiFi speed test?
Can I also please confirm that you're using the 5Ghz connection for devices closer the the Hub and the 2.4Ghz connection for devices which are further away from the Hub? As these are the best ways to use these two connections.
It may also help to ensure your Hub is out in the open and at least 1 meter away from any other electronics as this can interfere with your wireless signal coming from the Hub.
