No connection despite all tests and checks clear

[Lasty1]

For the second day running the WiFi has dropped. All lights on the router are fine. We have reset it. Turned it off and on again. 
tested broadband and WiFi in My Sky and all is clear. 
I'm trying to work from home and cannot get any internet at all. So frustrating. 
Tried to call sky yesterday and it said all lines were closed and call back between 9&9 but it was as midday.

If your broadband isn’t working and you haven’t done it yet 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. The easiest way is to dial 150 free from your Sky Talk landline if it’s still working.

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