Hello, well , perhaps someone knows about this:
I have scheduled the stops and restarts for the radios in the cron as
59 22 * * * /sbin/ifconfig wlan1 down
0 10 * * * /sbin/ifconfig wlan1 up
0 0 * * * /sbin/ifconfig wlan0 down
0 6 * * * /sbin/ifconfig wlan0 up
That causes the following system messages to keep displaying.
message daemon.err hostapd: Failed to set beacon parameters.
So, in order to stop the messaging the radio beams must be completely disabled. Not enough just to be stopped by the executing ifconfig commands.
I have no idea about this, probably a need to disable and enable the radios in the crone instead.
