WiFi constantly dropping

[TM341]

I've tried all the usual resets, disconnecting all equipment, re-booting and then switching sky glass and the extension sky gradually after re-boot.  Seems ok for 5 mins then WiFi drops again. 
Been like this for 24 hours now where all box lights show green and then WiFi light flashes and turns orange, and then repeats the process. 
All phone points re-booted so can't think of anything else we can do.  Home workers so WiFi imperative

Try running the line test here:

https://www.sky.com/help/articles/broadband-diagnostic-start

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.

If it doesn't find anything then give Sky a call.
