Any chance connecting 60 stations?

[dicaixa]

Hello,

I have tried recompiling the driver allowing for more stations, but the interface sometimes goes down and the stations try a reconnect.

The warning for no more room is triggered and a kernel event is logged.

Am I doing the right move?

This is with rpi 2 zero w with the lastest kernel.
