The ideal way to handle this would be to add an EM absorbing material to the ceilings. The reflections off the ceilings are causing self-interference, and because it’s curved and complex, standard noise correction doesn’t work.
To support MU-MIMO / beamforming (multipath signals for multiple devices) they could also just add more flat surfaces inside the ceilings to make radio reflections/echoes less complex so that the signal processing doesn’t get overwhelmed when the source is some distance away.
Plain absorbing material removes interference but doesn’t let you use MIMO tech as effectively, because the newer higher end routers can use those reflections to boost the signal
