Hello guys I have problem with changing wifi channel on my wireless card. I am in Norway at the moment and I live in Bosnia, when I came here I can't find home network. My theory is that I have problem with wireless card channel (I see many wireless networks but not one I want to connect to) so I am trying to change it but when I use command:

sudo iwconfig wlan0 channel 1

I get this error:

Error for wireless request "Set Frequency" (8B04) :
SET failed on device wlan0 ; Device or resource busy.

I tried using command: sudo ifconfig wlan0 down

and then change channel but I got same results.

This is info about my wifi card:

 wlan0     IEEE 802.11bgn  ESSID:"dlink"  
           Mode:Managed  Frequency:2.437 GHz  Access Point: 1C:BD:B9:B9:F7:44   
           Bit Rate=65 Mb/s   Tx-Power=27 dBm   
           Retry short limit:7   RTS thr:off   Fragment thr:off
           Encryption key:off
           Power Management:off
           Link Quality=62/70  Signal level=-48 dBm  
           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:55  Invalid misc:126   Missed beacon:0

I use toshiba satelite c660 laptop. After: lspci -knn | grep Net -A2 I got:

06:00.0 Network controller [0280]: Broadcom Corporation BCM4313
802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)     Subsystem: Askey Computer Corp. Device [144f:7175]

You need to connect to internet by wire and run in terminal

sudo apt-get install bcmwl-kernel-source

This will install the proper driver.

If you can't connect with cable, you can use an offline guide
