Broadband issues

[Kayleigb]

Hoping someone can help! 
I've had the new SkyHub broadband for the last month and the whole time the connectivity has been intermittent. The service checker on the app states there is a problem but when I run the checks it all comes back good. 
Ive now used all my mobile data and had to roll over my saved data to keep me going this month. I've spoken to customer service about it who were no help, basically told me it's a WiFi issue and potientally my phones security settings? 
they had me reset the network settings on my phone which also didn't help. But I tried to explain that's it not just my phone that won't connect, there's also another mobile, 2 iPads and an Amazon fire stick that don't connect. 
I'm really frustrated that I'm paying for something that doesn't work and I now have to wait until 6th May for an engineer! 
Does anyone have any ideas that I could try in the meantime?

Try this line test:

You can also run the test via the MySky app on a mobile data connection.

After this has finished and if it reports back all is good click on broadband to run an updated test. If you get amber or red please follow the on screen instructions.
