having problems with wifi on compaq presario

Hi everyone,

hoping someone can help this newbie. Installed opensuse on above laptop - previously had an old version of mint on it and was using an external usb drive with fedora 18. Have tried others incl. puppy which have found my wireless & set-up wiithout any issues. From what I remember in the past I have had to replace the driver the os was trying to use and due to wireless key on keyboard have had to enable it. However I’m no geek and could not do this again without help. Read the help with wireless advice on forum and tried the following (though it means nothing to me!)

08:08.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

Also used YAST to check boot message for firmware as instructed, found the message and followed instructions to download the firmware. It started to do this then went full screen scrolling down to something like:

panic…locked kernal? Had to shut down laptop, restarted it, no wiireless still

Can anyone help further?

Thanks Lez :frowning:

The Realtek device is your wired interface. The 14e4:4311 one is a Broadcom
BCM4311. BTW, ‘lspci -nn’ is a little more instructive, but still yields only
one line per device.

The panics started when the firmware installation script was changed to reload
the driver to pick up the new firmware without rebooting. Unfortunately, the
panic only happens on some systems, and unfortunately not mine. To prevent the
panic, the easiest thing would be to edit the installation script using


kdesu kwrite /usr/sbin/install_bcm43xx_firmware

Find the lines that say


/sbin/modprobe -r b43
/sbin/modprobe b43

and remove them. That will stop the panics. Rerun the script, reboot and your
wireless should work.

As you failed to say what desktop you are using, or even what version of
openSUSE, I gave you instructions for KDE. You should, however, always supply
that info.
