Power management

[ThaWalrus]

I'm using a Raspberry Pi 3.

The device becomes wirelessly unreachable after an hour or so. I figured a solution to this, which is disabling power management of the network device. This is done by either $this->bbcode_second_pass_code('', 'iwconfig wlan0 power off') or $this->bbcode_second_pass_code('', 'iw wlan0 set power_save off').

How to keep the power management off after rebooting the system?

Thanks,
me.

You can add your command to netctl@.service.

I am not using netctl, any alternative?

what is the kernel module ? chceck the args it supports with "modinfo". There is usually an arg that will control power management. If there is you can use modprobe to disable it on boot: https://wiki.archlinux.org/index.php/ke ... le_options

Or write your own service file with the appropriate command.

$this->bbcode_second_pass_quote('andiling', 'O')r write your own service file with the appropriate command.

It's easy to say something is much easier and write a "given the option is available"... I guess it depends on personal preference how to set up one's own system. However, yours would be definitely the cleaner way.
