BT Smart Hub 2 – Disabling 5Ghz Band
Many devices require a 2.4Ghz signal, and the bands cannot be split on the Smart Hub 2, therefore the only solution is to temporarily disable and re-enable it.
1) Open a new web browser on a device connected to your Hub and type 192.168.1.254 in the address bar. This will open the Hub Manager.
2) Click Wireless
3) This will open the Wireless Settings page. Select ‘Change settings’
4) Enter the Admin password. This is found on the back of the router and on the removable card. Click ‘OK’
5) Toggle 5Ghz OFF
6) Click 'Save'
7) Click 'Yes' at the warning prompt.
😎 Wait for devices to re-connect.
Repeat the steps above, but toggle it to 'ON' to enable it again.
Good post and explanation which should help others who have problems connecting to 2.4ghz network. The real problem is very few customers who come to the forum use the search facility before they post their problem which has been highlighted in the past but continues to happen

Thank you 😊
Yes, unfortunately so. But at least now, (while most people sort it) I have something to link to assist them.
Thanks for the detailed instructions,
after connecting about 14 devices immediately after receiving our Smart hub 2 with no trouble, we were dreading connecting our smart plugs, these took about 3 days of trying to connect just after Xmas to Smart hub 1, eventually did connect, so not looking forward this time.
We left then until last and sure enough would not connect.
We were even contemplating changing back to our old hub, but then just thought wed have to forgo the plugs.
Then came on here, was rather worried that I'd do something wrong so left it until the next day.
Took about 2 mins to disable 5Ghz, plugs connected immediately, then reversed the action.
I also disabled the Hub Manager, as someone mentioned, before I attempted the above, then again enabled it, not sure if it would have made any difference but did it anyway.
I'm sure your post has helped a lot of people, and ironically I know of others who had bought smart plugs of all description and returned them saying they did not work.
Thanks again
Thank you so much for this answer. I had tried so many different ways to attach my printer to the new smart hub 2 but to no avail. Was almost about to go and buy a new printer which I really did not want to do. Eventually found out it was to do with the signal that the printer needed to attach to but could not find an answer to how to attach until I found this discussion. This should definitely be more widely advertised to people as I'm sure there will be others with this problem now that more people will be upgrading their broadband.
of course all this grief could be avoided if single band devices worked properly.
From another forum, which seems a reasonable explanation why some devices have a problem and others don't.
From what I understand when a wireless client speaks to an access point, the access point asks the client what it supports.
The 2.4 only client states 802.11b, 802.11g and 802.11n.
The 5ghz only client states 802.11a, 802.11n and 802.11ac.
Some of these 2.4ghz devices seem to not know that 802.11n supports 5ghz.
So the client states I support 802.11n, and the access point tries to connect the client to 5ghz.
So I put it down to lazy programming in the client.
Thank you Chromecast working perfectly since changing to 2.4Ghz on Smart Hub 2 as you recommended via 192.168.1.254
A great suggestion in theory... unless you have noise in the 2.4GHz band. Everytime I play a YouTube video or do anything else with a high-bandwidth requirement, my connection drops on all devices.
