Wireless networks not detected [solved]

Hello,

I have installed mandriva 2009 yesterday. Everything works great - but the wireless networks.

Windows XP detects two wireless networks as shown in the screenshot attached. But, Mandriva detects none. I don't think there is any problem with the installation or drivers but.. not very sure. Here are some of the outputs you might be interested to look at.

 

[root@localhost rama]# ndiswrapper -l
bcmwl5 : driver installed
       device (14E4:4311) present (alternate driver: ssb)
[root@localhost rama]# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

wmaster0  no wireless extensions.

wlan0     IEEE 802.11bg  ESSID:""
         Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated
         Tx-Power=0 dBm
         Retry min limit:7   RTS thr:off   Fragment thr=2352 B
         Encryption key:off
         Power Management:off
         Link Quality:0  Signal level:0  Noise level:0
         Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
         Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Try doing this in a console window, and see if you get any results:

 

su (enter root password when prompted)
iwlist wlan0 scan

 

if you see any results, you are seeing access points but is strange if you see them here and not in the gui tools.

Hi Ian,

Thank you for the reply. I am not able to see any wireless networks in iwlist as well. It says network is down. Here is the output.

 

[root@localhost rama]# iwlist wlan0 scan
wlan0     Interface doesn't support scanning : Network is down

[root@localhost rama]#

 

Did I miss anything in the installation?

You could try:

 

ifup wlan0

 

first and then retry the scan command and see if it's any better. Otherwise, I'd say there's some sort of problem with the ndiswrapper stuff - maybe wrong driver.

When I try ipup wlan0, it gives this message-

Error for wireless request "set Mode" (8B06) :
   SET failed on devise wlan0 ; Invalid argument.
Another wpa_supplicant instance is already running for device wlan0

 

Please help!

Hi,

I have read in one of the forums

"http://www.linuxquestions.org/questions/linux-wireless-networking-41/error-error-for-wireless-request-set-mode-8b06-invalid-argument-roaming-506735/"

that they got rid of this error by change from Mode=Auto to Mode=Managed

I did the same thing in configure network option.

It now doesn't say invalid argument now. It just displays this error message-

Another wpa_supplicant instance is already running for device wlan0

After changing this, I suggest you reboot and see if it's any better. Otherwise, you need to kill the wpa_supplicant process before reconfiguring your card.

 

If that still doesn't work, follow the ndiswrapper wiki and make sure you have the right Windows driver for your card. The lspci output generally will tell you which version you should be installing, but the ndiswrapper wiki tells you exactly how to go about all this. Try the above first though, killing wpa_supplicant, and then reconfiguring to mode managed and see if it's any better after that. If not, you'll need to check your driver versions with ndiswrapper wiki and make sure you have the right version.

Hi!! Thanks everyone for all your help!! I was trying for solution and have found this thread in our forum

 

https://mandrivausers.org/index.php?/topic/29019-nvidia-controller-ethernet-solved

 

It advised me to add adding forcedeth to /etc/modprobe.preload. I just did that and its working great now!!

Thank you for your help and time..
