How do I change to 2.4mzh on the 3.0 hub and where would I find the password to log in please 

[Tudor]

Password should be on bottom of hub or a pull out card. Just look at the settings once logged on.

Those details have been entered. I will check and try again.

Thanks

The hub uses 2.4GHz (not mhz) and 5 GHz together for WiFi by default.

If you want 2.4GHz only for some reason disable the 5GHz (at least temporarily) in advanced settings as shown Here 

You can also give the bands different SSIDs to set them apart

The reason why I ask.  I have a doorbell and several smart plugs. None of which have connected.

Do this
----------
If you haven't done this already - try it first - it helps sort some Hub3/4/5 wifi issues for some devices.
Go into the Hub’s settings. Type in  http://192.168.0.1  into your web browser’s url box and login with settings password on the Hub's base sticker (or your own if you changed it). Then in Advanced>wireless signal >smart wifi - tick the disable “channel optimisation” box or “Smart Wifi” box and save settings.  May be different pathways and wording on the 3 Hub types
Then, go to advanced>wireless signal>security, rename the 2.4 & 5 GHz network ssid's.  Just type over to change 'em to whatever you like and something that will differentiate them (e.g - Billybob2 & Billybob5) Try to avoid spaces and periods in the SSID names as they can cause issues with certain devices. Use the same password for simplicity,  Then, apply settings and restart the Hub.  Your 2 wifi networks will now be clearly separated - and you can then select the network you want each device to connect to… individually from the "available networks" list on each of your devices. 

Note all your wifi devices will need re-connecting to the new SSID's and passwords.
All things being equal, 5 GHz is always better/faster and subject to less congestion/interference (and is better for iDevice speeds than the 2.4 one - although the 2.4 one has the better "range" and will be needed when the 5 GHz drops out of range and some older/cheaper/dumber devices can only use this one. 

You should also use a wifi analyser App (or Airport Utility on iOS) to check which 2.4 channels are being heavily used around you and move yours to one of numbers 1,6,11 that is least so, but it wont help if there is other interference.
See if these changes help - you will lose any “seamless roaming” benefits but it may not matter and you can always change the settings back by doing a " pinhole factory reset " if you prefer the way it was - or it doesn’t help.
