Sky Q and Minibox - booster?

[Tyre Smoke]

We have a Sky Q box in the sitting room, and more or less directly above it is a minibox.

Most of the time they connect okay, but the engineer did say when he was installing it that we might need a booster. We live in a barn conversion and the floor/ceiling is quite thick.

My question is, do I need a Sky booster box, or will any plug in wifi booster work? There's a big difference in price!

Will they do that? It's been over a year since the install.

Can't cable between the two, walls are too thick.

Thanks for that, I'll do that when I'm home later.
