This guide shows you how you can disable the Smart Setup feature on the BT Home Hub which apparently has effects on Kodi that stop it from working as it should.
Open the web browser on a computer or device connected to your Hub and go to http://bthomehub.home to open the Hub Manager.
Click on Advanced Settings:
Enter the admin password. Unless you’ve previously changed it, you’ll find the default password on your Hub settings card on the back of your Hub. If you have changed it and now forgotten it, you can use the password override feature to set up a new password
Click on Continue to Advanced Settings
Click on Home Network and then Smart Setup
Click the appropriate radio button (‘NO’) to disable the Smart Setup and then click Apply
All should now be working on your Kodi XBMC.
