Wireless no list of broadcasting networks

English Network/Internet
#1

[FONT=“System”][FONT=“Courier New”]My wireless network doesn’t work. I get no list of broadcasting networks. I have runned ‘collectHWData.sh’. This is the output. Does anyone know what I should do to make my wireless work? The problem occurs on my clean installation of SuSe 11.3 on my laptop PC C500 Compaq.

The script shows that you have not yet installed the firmware. Confirm that with

dmesg | grep b43

With a wired connection, run the command

sudo /usr/sbin/install_bcm43xx_firmware

#4

Hi.

Just a little question for you entropy2 : where did you find this script ?

#5

Sorry, I spelled it incorrectly: collectNWData.sh is what it should read.

#6

I did what you said, and now it works all beautifully. Thanks!

(Did I mention I am a newbie? ;))

#7

No problem, I glad to read that it works If you want help you go to Hellas subforum and write your problem.
Please read my advice who I have written Τεκμηρίωση(Documentation)](http://forums.opensuse.org/greek/i-i-i-i/i-i-i-iui-i-i-i-i-i-i-i-i-i-i-i-i-isi-i-i-ioei-i-i-i-i/i-iui-i-i-i-i-i-i-i-documentation/). This guide has been written by my friend Stathis, the other advice have been written by me.

But where did you find it ?

Thnaks. :slight_smile:

Hi i have the same problem. I don’t know how to get list of wifi networks. Last time (i dont know how), i got the list, but after reinstalling open suse, there is no list. I am using laptop.

#12

I try to write this sudo /usr/sbin/install_bcm43xx_firmware but it said that commadn no found.

Please do not blindly follow things that you see in the list. Usually if the
installer finds Broadcom hardware, it will install the firmware cutter, and this
command will be found.

Please try the following command:


/sbin/lspci -nnk | grep 14e4

If that command produces some output, then the installer messed up and you may
need the firmware. In that case, connect to the Internet with a wired interface
and do the following:


sudo zypper install b43-fwcutter
sudo /usr/sbin/install_bcm43xx_firmware
sudo /sbin/modprobe -rv b43
sudo /sbin/modprobe -v b43
sudo /usr/sbin/iwlist scan

If you really have Broadcom hardware, the scan should now show neighboring
networks as long as your radio enable switch is on.

If the first command above does not produce any output, then post the output of


/sbin/lspci -nnk
