WiFi won't be the best way to play but try these suggestions, they may help make it more stable.
Disable Mirror Mode, give 2.4/5GHz different names and apply - you'll want to connect to 5GHz specifically for speeds
Use a WiFi analyzer to find the least congested channel and change to that
Experiment with the widths to see what gives better results
Ensure it's in an elevated position - not on a metal surface
Ensure there aren't any electrical / wireless devices e.g headphones etc within close proximity ~3 feet if possible
Set the antennae to this position _ | | _
