Why does the sky broadband 'test' tell me its working when it clearly isnt?

[Huntsman64]

Unfortunately due to the age of the house I've moved into I can't have fibre, so I have 'superfast' plug into the phone line broadband.  It is incredibly unstable, and is currently off.  Why does the test tell me it's working when it isn't?  The box has 4 lights, power and wifi are green, Internet is off completely and voice is orange.  Noting is working!!!

If you haven’t done it already use the below link to check to see if there are any problems or outages nearby
https://www.sky.com/servicechecker
(This should determine if there's an identified fault affecting multiple households)

If there aren't any then try running the line test here

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

Once completed, if it reports back that all is good click on 'broadband' to run an updated test. If you get amber or red you need to follow the on-screen instructions.

If you’re still having problems you may need to call Sky to report it. Dial 150 free from your Sky Talk landline (if it’s still working).
