Wifi speed keeps dropping

[Stewalt]

I have issues with my wifi constantly dropping out or running extremely slow. This is from connection of my main box or when connecting through sky q minis. I'm getting readings of 5mbps. To 20mbps. However I test it on my skyq app and it's saying 102mbps which is not what I am getting from 3rd party readings. And I am experiencing lots of buffering so I'm guess the 3rd party apps are correct

Having 100Mbs at the Hub and struggling wireless devices is entirely plausible, because broadband is not the same thing as WiFi

Doesn't really help.  Cheers
