Wifi issues - droppy connection, packet loss etc

[CrystalPalace63]

I have a Wifi problem. Connected directly to ethernet, my laptop is fine. On Wifi it's dreaful. Tried on multiple Macbook Pros, all the same thing. Feel the same on mobile devices. Even when very close to the router over wifi, I get issues. Stats are below. How can I go about diagnosing this futher?

Thanks

Do you have Sky Q? If so how many nodes?

How many devices are connected to the WiFi at a time?

[CrystalPalace63]

Hey. Yep, I have Sky Q in living room (which is nearer my office than the router) and one extender box. Connected to the wifi at any given time will be: two phones; two macbooks; Hive hub; Philips Hue hub; Google Home Max speaker. I'm pretty sure that's all.

Is it any better if you disconnect the extender? These kinds of problems where you see disconnecting/stalling WiFi are often down to too many mesh nodes and/or a node which isnt meshing properly. 

[CrystalPalace63]

Yeah, you're right, the extender actually makes the wifi barely usable, which is annoying.
