Sky Q keeps dropping wifi

[Rebcca]

My Sky Q keeps dropping from my EE internet on WiFi !  I thought to hard wire this with an ehternet and turn the wifi settings off on the sky Q box bit then my mini boxes wont connect . I have had EE engineer out and the Internet is fine they say ! Does EE and sky have issues ? I used to be with BT and had no problems ! It seems to only be sky that drops out maybe the Sky Q box needs replacing ? Any ideas ?
