Broadcom wireless BCM4312 immediately disconnects on Slackware 13.37


I have a problem with the built-in wireless-card of my laptop. I can connect to the wireless DSL-router using wicd (wicd-1.7.0-486-2 from /extra), wicd reports that it connects and obtains an IP-address. It then changes the status to connected. Immediately after that (may be a second later) the status changes back to disconnected and I can't reach the network.

Here some specs:
Kernel: self-compiled 2.6.37-6-generic, the only option I changed from the standard generic config was to enable PAE, but I also tried it with the standard generic kernel and the huge kernel.

Wireless card: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

Firmware installed with the packages from Slackbuilds.org: network/b43-fwcutter network/b43-firmware

The wireless card is working correctly under Debian, so I think this is not a hardware issue.

I hope anyone can give me a hint or a link to a solution.

Thanks in advance.

I have the same broadcom card. I use the broadcom-sta driver with great success. I blacklist the b43 and use wicd and all is fine.

Thanks for your answer.
OK, I tried that (installed the driver from Slackbuilds.org), but that doesn't even show up any wireless network, and iwconfig doesn't show the wlan0 interface.
The b43 module is blacklisted (and not loaded), and lsmod shows that the wl-module is correctly loaded, but sadly this seems not to work.

Any other suggestions?

Your wireless interface should have changed to eth0 (or ethX) since 'wl' is being loaded. You may also need to blacklist 'ssb' to have 'wl' working correctly.

OK, after blacklisting ssb the machine came up with an eth1-interface (eth0 is the wired connection). But I still can't connect to the router using wicd, it reports that it can not find a wireless network even when I position the laptop direct next to the router.

So currently it comes down to this: Using the b43-driver I can see the network and connect to it, but it immediately disconnects after connecting. Using the sta-driver I can't see the network at all.

I would be very thankful for further help, I am totally clueless.

Have you changed your wireless interface in wicd's 'General Settings' page? Otherwise it leaves 'wlan0' in the field.
You could run 'wicd-curses', then press 'Shift+P' to check your settings.

I have this card. For the b43 driver you need to pass the options pio=1 and qos=0.
Code:
modprobe -r b43
modprobe b43 pio=1 qos=0
Add to modprobe.conf
Code:
echo "options b43 pio=1 qos=0" >> /etc/modprobe.d/modprobe.conf
For the wl driver, you have to go into the wicd preferences and change the interface name to eth1 for whatever it is there.

I don't know what happened. After answering a few posts here (using the wired connection) I clicked on the wicd-icon once more and suddenly I could see the network. It connected, and it stays connected (posting this using the wireless connection).

jkirchner and yuuko, thanks for your fast help with this issue.

reed9, also thanks for your help, have seen your post to late. Since it now works with the sta-driver I won't change back.
