If you use decent WiFi gear and you're not after milliseconds of difference you should have no issue.
However, if you're in a high density area go wired every time.
If you have a large home and brick walls, install multiple WIRED access points. I use Ubiquiti Unifi gear and have 4xAPs.
If you don't understand overlapping frequencies get an IT/Comms/Network guy who knows his shit to do it.
