Proper disabling of WiFi power management

edit

I know it's a little late, but hope it helps others that have the same question.

Create a NetworkManager script i.e. /etc/NetworkManager/dispatcher.d/02-wlan-powersave-off

#!/bin/sh
IF=$1
STATUS=$2
if [ "${IF}" = "wlan0" ] && [ "${STATUS}" = "up" ]; then
   iwconfig ${IF} power off
   logger "${IF}: turning off powersave mode to prevent constant reconnections"
fi

Don't forget to chmod 755 /etc/NetworkManager/dispatcher.d/02-wlan-powersave-off

Restart NetworkManager (using Fedora with systemd):

systemctl restart NetworkManager.service

One option would be to add this to /etc/rc.d/rc.local, and enabling +x on this file.

$ vim /etc/rc.d/rc.local $ chmod +x /etc/rc.d/rc.local

Personally, this needs to be fixed in kernel, or NetworkManager code.

Great answer in https://ask.fedoraproject.org/en/ques... ! Here are my two cent that make it work regardless of the interface number or names:

IF=$1
STATUS=$2
ifaces=$(iwconfig 2> /dev/null | grep "802.11" | awk '{print $1})
for iface in $ifaces; do
    if [ "${IF}" = "$iface" ] && [ "${STATUS}" = "up" ]; then
        iwconfig ${iface} power off
        logger "${iface}: turning off powersave mode to prevent constant reconnections"
    fi
done

Disabling Power Management just worked yet again. Surface Pro 3/ Fedora 26. Thanks for the info.

Based on this Ubuntu based solution I did the following.

sudo vi /etc/pm/power.d/wireless

Then paste the following and save the file

#!/bin/sh
/usr/sbin/iwconfig wlan0 power off

Finally, make it executable

sudo chmod +x /etc/pm/power.d/wireless

This should make power management be off on reboot.

Follow the below steps -

# su -
# vi /var/lib/NetworkManager/NetworkManager.state

In the file you will see the below contents -

[main]
NetworkingEnabled=true
WirelessEnabled=true
WWANEnabled=true

Change the value of WirelessEnabled=false

Restart the NetworkManager

# service NetworkManager restart

This should work !!
