Sky mini and Q womt stay connected to wifi

[Gamer01000]

This is really **bleep**ng annoying my sky mini and Q won't stay connected to Internet I only have 9 devices connected less when some are switched off but even then the **bleep**ng things won't do as they are told sky has already sent a bt engineer out once the Internet connection improved but now the issue is with mini and Q. I think the issue is with those 2 abd sky are to lazy/dumb to know how to fix it so does anyone here know?.
