In what way? Your question is too vague.
What device(s)?
How far from hub?
Which Hub?
What WiFi band?
Do all devices suffer? Are wired connections OK?
depending on all that, and other factors, do a WiFi scan with a suitable app, find best channels and switch to them and so on.

I know a bit about Wi-Fi, Telecoms, and TV as I used to do it for a living but I'm not perfect so don't beat me up... If you make things you make mistakes!
