Wireless Power Management?

Hello, I am running OpenSuse 12.1 in with KDE. My wireless was working with knetworkmanager on 11.4 before I made the jump. In 12.1 however, I was unable to get knetworkmanager to work, so I tried to use ifup. I was able to set up my network and connect to my AP as shown by the /usr/sbin/iwconfig command.

wlan0     IEEE 802.11bg  ESSID:"Network"  
          Mode:Managed  Frequency:2.412 GHz  Access Point: ##:##:##:##:##:##   
          Bit Rate=1 Mb/s   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=70/70  Signal level=-5 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

However when I tried to run it with the ifup wlan0 command, I get this message

wlan0     name: BCM4312 802.11b/g
command 'iwconfig wlan0 power period 2' returned
 Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan0 ; Invalid argument.
    wlan0     warning: wpa_supplicant already running on interface
DHCP4 client is already running on wlan0
IP address: ###.###.#.###/##
DHCP6 client is already running on wlan0

My wireless is refusing to work, and I have no idea whats going on, but I’m guessing it has something to do with the power management.

Any help is appreciated

Switch back to network manager

Post the result of

/sbin/lspci -nnk

That “error” message is not your problem. It causes no difficulty, and appears
because iwconfig is obsolete, and not all of its commands are implemented.

What driver are you using for your BCM4312?

Had a similar issue - http://forums.opensuse.org/english/get-technical-help-here/wireless/469447-flaky-wireless-power-management.html

Work around is changing the power management setting in /etc/sysconfig/network/ifconfig-wlan* to “none”.

I have the same problem after update - wireless does not work!

I wonder why it is marked as “solved”? I have this issue after upgrading to openSUSE 12.2!

Considering that you’re responding to a thread that’s almost a year old,
chances that for the user who asked the question, they got it working.

If you’re having a new issue with this with a new version of openSUSE, you
might start a new thread and provide some details.
