worse than that, it causes grief on other stations further away that can hear 
one station and not the other.

Splitting things so that user access is on 2.4G and relaying between APs is on 
5G will help quite a bit. If you can add some directional antennas on 5G, it 
will help as well

Even without being able to wire everything, if you have any that you can wire 
together it will help
