Broadband wifi going on and off for the past 4 days

[Oli5]

Hi, our home broadband is going on and off for the past 4 days, run the test and it says everything is ok? The broadband router when this happens flashes orange and red then goes to green when comes back on. Why is this happening please when it says the tests run are fine

If you haven’t done it already use this link to check to see if there are any broadband problems or outages nearby.

This should determine if there's an identified fault perhaps 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).

This link providers information about the coloured lights on the various hubs

Its worth adding that for customers working from home remember that Sky Broadband is a domestic service so you won’t receive any extra or quicker support.
