Can't turn off WiFi Power Management with iwconfig

I had an issue with my WiFi connection dropping occasionally, and I found that my situation was the same as described in this part of the Wicd wiki article: <https://wiki.archlinux.org/index.php/Wi … connecting>, so I used iwconfig to turn power management off, like it said. But, the disconnecting issue is still there. I think power management is still on, because of this:

[<...>]$ cat "/sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/net/wlan0/power/control" 
auto
[<...>]$ cat "/sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/net/wlan0/device/power/control" 
on

Yet, iwconfig still shows that power management is off:

[<...>]$ iwconfig wlan0
wlan0     IEEE 802.11bgn  ESSID:"<...>"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:21:A0:F9:FD:C3   
          Bit Rate=54 Mb/s   Tx-Power=15 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=48/70  Signal level=-62 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:2  Invalid misc:239   Missed beacon:0

Re: Can't turn off WiFi Power Management with iwconfig

Haven't had this problem since I switched to NetworkManager, even with power management on...
