Hello
I'm having similar issues with the Super Wi-Fi Booster tile not appearing within the Vodafone Broadband app. Though I may have found a solution that I hope will help you, or at least others who land on this page and are reading this, desperate for a fix to the issue. If you haven't updated the Vodafone Broadband App though, please do this first before following my advice below.
On a laptop/desktop or any other PC (not a mobile device/tablet/smartphone) open your usual internet browser and enter into the address bar 192.168.1.1 and it'll allow you to login to your router, giving you access to it's settings. You will need your routers' password which can be found on the information sticker on the bottom of it. You'll see your network and password information on the left with the QR code to quick connect from your phone etc (you may have already used this to get your devices connected) but to the right you'll see the IP address I mentioned above then your unique router password below it. The IP address will be in bold.
Enter the password shown into the prompt/box that comes up on screen within your browser and it'll log you into the router (please bear in mind this is case sensitive). Once logged in you'll see several tabs with a red background (Overview, Internet, Wi-Fi, Sharing, Settings then Status & Support) but above that will be a grey bar with a drop down menu top right. Click that and switch to 'Expert Mode'. This will give you additional options - one of which will be 'Firmware Update' which can be found under the red settings tab. It's the second option below password.
Click the Firmware Update option. It'll allow you to check for an update and let you know if one is available. This will take several minutes and it may temporarily disconnect any connected devices until it finishes the update - they'll automatically reconnect though. Please note that unless you're sure on what all the other settings and options mean - avoid messing with anything else as you may get disconnected or change the set up of your router and any further settings changes should be done with guidance from an expert (whether that's Vodafone or another third party). Though checking for a Firmware Update is pretty straight forward using this option and you won't cause any harm.
Let me know if this worked for you.
