No Network Connection with Live CD

Is it normal to not have a wireless connection when running OpenSuse KDE 64bit from the live CD? It appears that the system does not see any wireless connections. The wireless tab in the control manager is not active.

2 issues
Your device requires firmware

In 12.3 the network was broken and requires a reboot.

Your device does work. I have the same machine and device.

Are you wanting to try and get it up and running in a live session? It might be possible, but it’s fiddly.

But if you install, then post install

The firmware you need is here
LINK REMOVED

The 2 folders go to /lib/firmware, but you actually only need the one b43

Post install, inspect the dir. /lib/firmware
If you have a folder already ‘b43’
We need to rename it
Open a terminal in /lib/firmware and do

su
mv b43 old-b43

Then open a terminal where you have the folder I gave you and do

su
mv b43 /lib/firmware

Then reboot

This archive is illegal. Broadcom expressly forbids the redistribution of their
firmware. By publicly posting this, you could be in severe trouble with them! Do
you really want to have their lawyers after you?

The prohibition of redistribution of Broadcom’s firmware is the reason that we
jump through all the hoops associated with install_bcm43xx_firmware. That method
is unhandy, but legal.

If what caf4926 says is illegal, what should I do to make it work? I would like to use it from the live CD for a little while before deciding to install.

Would using 64 bit vs 32 bit versions make any difference?

Is the problem the same if I install OS?

64 / 32 makes no difference

Use a wired network connection instead, or plug in a wireless dongle
that uses better-supported chips.

Once you have the firmware. Do as I do and keep a copy on a pen drive and copy over to the live session of /lib/firmware
then modropbe like this

su -
modprobe -rv b43
su -
modprobe -v b43

The firmware runs on the CPU on the board. It does not care if you have x86_64,
x86_32, ARM, PPC, or MIPS architecture. As caf4926 says, you can keep a copy of
/lib/firmware/b43/ and /lib/firmware/b43legacy/ on any external medium, and copy
the files in those directories onto whatever system you are trying to run. Newer
firmware versions are usually to support a new device type. If you have the
firmware, it will likely work with your newer system.

With the Live medium, if your existing system has those files on an older system
on the hard drive, you can also mount that drive and copy the files. Of course,
you will need to do that every time you reboot the Live medium.

We tried very hard to get Broadcom to allow redistribution of their firmware;
however, their lawyers claimed that doing so would subject the company to
liability issues as they had no control over the drivers that would be used, and
someone might use the wifi device in an inappropriate manner. The claim is
bogus, but you know lawyers.

I have the firmware update files. I think, while “playing” with the livecd, the hardwire solution might work best for me. I’ll try both ways and see.
One last question, please: Do I correctly assume that b43legacy is for the purpose of returning to original firmware if needed?
Thanks for all the help.

Did we not point you here: b43 - Linux Wireless

It should tell you what you need to know
But you assume incorrectly. b43 and b43legacy just support different devices
Your device uses b43

I think it’s probably the same as mine

Thanks for the info and the link. I’ll read it and see how much I understand.
