Single device connection issue

[morris12345]

I've had sky since December, prior to that I had BT for the 2 years at the same speed, changed due to price difference.

It's a new build so fibre to the property, the connection on most devices seems fine but my work laptop (over WiFi not wired as router is downstairs and office upstairs) connection drops and is really poor when it is connected, eg for a Teams call.

The Router is situated in a cupboard downstairs but this doesn't seem to affect the connection to our phones tablets when in the same room as the laptop (recently had a new laptop so isn't that either). There is a mini digi sky box approx 3 metres from the usual place I work which should boost signal? 

I'm lost for what to try?

Would be useful to know the make and model of the laptop and which Sky router you are using. Generally speaking, Sky's routers are worse than BT's for performance, range and features. And so are the Sky boxes for wireless performance...
