Wait a minute and then you may check if power management if turned off: iwconfig wlan0 | grep "Power Management"Įven if something triggers the power management to turn on, it will last only a minute. Paste this to the end of the file: */1 * * * * /etc/pm/power.d/wireless_power_management_off If you never edited crontab before, it will ask what editor you wish to use, this is totally up to you. Next, you need to set proper permissions to the file, rwx for owner: sudo chmod 700 wireless_power_management_offįinally we will be executing the script every minute using CRON dirty but worky: sudo crontab -e Owner of the file should be root, if you created the file as normal user somewhere, go to the folder where it is and fix it with: sudo chown root:root wireless_power_management_off Gksudo xed /etc/pm/power.d/wireless_power_management_offĮnter the following contents to the file: #!/bin/bash with gedit (LM17) or xed (LM18): gksudo gedit /etc/pm/power.d/wireless_power_management_off if you want to create the file graphically, eg. So one of possible solutions is as follows step-by-step.Ĭreate a directory, where you wish to store the file, if not already having one for all your scripts, I personally want to have it in /etc/pm/: sudo mkdir -p /etc/pm/power.dĬreate (anywhere you like) a script, name it to be sensible, for me it is: sudo nano /etc/pm/power.d/wireless_power_management_off There are probably hooks like if I plug off power adapter. It is not sufficient to turn off wireless power management at boot. I don't think this question applies only to Linux Mint, it is a general issue of particular wireless adapters. Tx excessive retries:2 Invalid misc:18 Missed beacon:0

I entered these two lines into the file: #!/bin/bashĪnd I finished with setting proper user rights: sudo chmod 700 /etc/pm/power.d/wireless_power_management_offīut after reboot the power management is back on. Sudo nano /etc/pm/power.d/wireless_power_management_off I followed these steps: sudo mkdir -p /etc/pm/power.d All of them contained the first step "Go to directory /etc/pm/power.d", which in my case did not exist. I read some articles about making the fix permanent. Sudo iwconfig wlan0 power off works, until I reboot the laptop.Īlso, if I randomly check iwconfig, sometimes it's on, despite I did run this command. I want to turn it off permanently or some workaround on this issue. In Linux Mint 17.3 / 18 iwconfig says the power management of my wireless card is turned on.
