New to Fibre now have WiFi dropping out

[Petrina6]

Hi

I would appreciate some advice.
We moved to Full Fibre 150 last week (just new to our village) and for the first 6 days it was perfect, however the WiFi has now started to dip in and out (this can be seen on a WiFi checker) throughout the house. The Sky hub keeps having different red lights on it. The Sky Q box and 2 mini boxes keep going off. Mobiles keep switching to 4G.
I have run all the Sky tests and fixes and followed the Captive WiFi' instructions but it is still the same. Not sure if we need a replacement Sky hub as ours is a few years old and they didn't send a new one when we moved to Fibre.

Really frustrated as thought Fibre would give us a much better service.

Do I need to call Sky?

@Petrina6 is the ONT unit on the wall showing a red light when you lose connection? If it is there is a fault with the fibre connection which while rare can happen where the weld joining the cable from the unit to the cable from the street is not perfect. Look at the lights on the hub as they can help understand what is going on see https://www.sky.com/help/articles/hub-lights-explained-start

Hi Chrisee

The lights on the ONT are green (apart from the alarm one which is not illuminated). The line to the property seems fine on the tests. It is the Sky Hub 4.2 which seems to have gone weird. First it was the Voice light which went amber - then came back in after an hour. Then in the early hours the internet and voice ones were amber. 
When the engineer connected us last week he tested the WiFi in each room and it was perfect. It just seems to have gone downhill since....dipping in and out, sometimes good, sometimes very poor.

@Petrina6 there is likely not a fault either with the hub or the line. The amber voice light is indicative of a fault at Sky's end completly not unconnected with the switch to full,fibre it is just coincidental. What happens is your connection is managed by a node on one of Sky's servers occasionally these dont work propely and stop routing data  correctly which is why the voice line goes down.

The fix is to power down the hub for an hour which should connect you to a new node which should connect properly.🤞

Thank you Chrisee for your time in replying. 
I am not techy so are you suggesting that  I should switch off the hub only or the open reach ONT as well?

[Petrina6]

I have switched off for an hour and the problem is still there.. 

what is the best way to contact Sky? We run our business from home and this is seriously affecting our work.

any further help would be appreciated
