I installed broadcom_wl with zypper in broadcom_wl AND firmware with zypper in b43-firmware. And manually installed hybrid_wl which is drivers for old broadcom cards.
I even changed kde to gnome and shifted from ifup to NetworkManager to test if it was the problem, however after all this I only got the followings.

linux-jxf2:/home/haha # iwlist eth1 scanning essid Dlink-ag
eth1      Interface doesn't support scanning : Invalid argument

The networkmanager just cannot find any exisiting wifi signals.

And manually add wireless network cannot connect successfully.

What is the problem ? Was it because all the drivers didn’t suit to the xen kernel ? Then where can I find the proper driver for it?

12.2 is at kernel 3.4.47 now. And the Packman packages are built for that kernel, so I’m not sure if they’ll work with 3.4.6.
So either update your system or try to download 3.4.47 from the update repo manually and install it.
http://download.opensuse.org/update/12.2/x86_64/kernel-xen-3.4.47-2.38.1.x86_64.rpm

Was it because all the drivers didn’t suit to the xen kernel ? Then where can I find the proper driver for it?

Well, what driver package did you install in the first place?
On Packman there is a xen kmp package as well:
PackMan :: Informationen zum Paket broadcom-wl

You would need broadcom-wl and broadcom-wl-kmp-xen from there.
And better remove that manually installed hybrid_wl driver, it could interfere.

If you do have internet access (wired?) then just add the Packman repo and install those two packages with zypper:

sudo zypper ar http://packman.inode.at/ Packman
sudo zypper in -f  broadcom-wl broadcom-wl-kmp-xen

But better uninstall the already installed broadcom-wl package first.

After re-reading your post again, I think you already added the Packman repo, but just didn’t install the package “broadcom-wl-kmp-xen”. So “zypper in broadcom-wl-kmp-xen” may be all you need (after maybe updating the kernel).

3

Yeah, I forgot to mention that I intalled the brroadcom-wl-kmp-xen. Nevertheless, I do update the kernel to 3.4.47 as you said, unistalled and reinstalled the broadcom-wl and broadcom-wl-kmp-xen. However, the problem stays the same. The wireless card just cannot scan for wifi. BTW, the update didn’t change the bootloader which cause a break of booting. I fixed the boot problem by manually change the 3.4.6-10 to 3.4.47-38 everytime it reboots. If you guys got a solution to fix it permanently please tell me.

4

And have you removed that hybrid_wl driver? As I said it could interfere.<br>
<br>Are you still using NetworkManager now?<br>
<br>In your first post the wlan interface shows up as eth1.<br>
Is this still the case? That would be strange, it should be wlan0.<br>
<br>Maybe you are missing the blacklist file /etc/modprobe.d//50-broadcom-wl-blacklist.conf?<br>
<br>
And please post the output of “lspci -nnk”, that should show which driver is actually in use.

5

Yes, I removed the hybrid_wl, and still using NetworkManager. The wlan interface still shows up as eth1.

I’m now trying to update the whole system and see if it works.

6

After updating the whole system, the problem still exists. I am now considering abort the wireless card since there’s no solution…Or should I use a usb wireless card ? Things just don’t go right.

7

Hm. So the wl driver is in use, why does it show up as eth1 then? :
I think because of that NetworkManager might confuse it with an ethernet adapter and control it incorrectly, causing your WLAN not to work.

An idea struck my mind:
Maybe you have an udev rule that renames the wlan interface to eth1?
Could you please post the file /etc/udev/rules.d/70-persistent-net.rules ?

Can’t see eth1.

sorry for everyone, its my stupidness that I forgot to turn on the physical switch. It takes me almost three days to find the problem which concludes to a lesson： the nearer you see, the easier to be cheat.
Thanks, everybody！

Glad you found the switch. The stickies should probably be rewritten to
emphasize checking the switch. They are now quite old, but I have no time for that.

By the way, NetworkManager does not care what the interface is named. A wireless
device can be called wlan0, eth1, or even xyzuvw9, as long as its driver
registers the wireless capability with the kernel. Only if you use ifup is the
name really important as that decides what configuration file to use in
/etc/sysconfig/network/. Of course, using ifup to control wireless should only
be used if really needed, and you know what you are doing.
