No wireless in 9.10 with Broadcom BCM4312

[gubbi.fisk]

Hi

I just upgraded from 9.04 -> 9.10 and that made me loose my wireless connection. I'm running the 32-bit version. In "Hardware drivers" the "Broadcom STA wireless driver" states that it's activated and currently in use. When I try to connect it does all the things, but fails on getting the IP-address (there is a long time-out, or some thing). My laptop is Acer Extensa 5220. As the title says I'm using a Broadcom BCM4312 wireless card.

I tried:
Reinstalling the driver package

In WICD I tried:
Changing from wext to hostap, madwifi, atmel, ndiswrapper ect.
Changing from external to ioctl

But no luck.

In terminal "lspci -v" outputs:

04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
Subsystem: Foxconn International, Inc. Device e003
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at f8000000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: wl
Kernel modules: wl, ssb

Please help!!

I noticed that the driver loaded is wl, but the driver in use is wl0 does this mean anything?

Wireless now working. (Hopefully for good)

All I did was:

sudo apt-get upgrade
sudo aptitude reinstall bcmwl-kernel-source

I don't know if i'll work for any body else, or me for long. But feel free to try!

Didn't work for me

Lenovo G530 with the same chipset BCM4312.

I've tried the same with 9.10 on a Dell Inspiron 1720, 4312 b/g wireless. Did not work for me. I've tried the hybrid drivers from Broadcom @ http://www.broadcom.com/support/802.11/linux_sta.php
I've tried the b43 driver, and the STA driver from Ubuntu restricted drivers. Just can't get the thing to even show up.

Same here with the Broadcom STA driver. I previously had the 9.10 Koala netbook remix version installed and it worked great in that. Now that I've installed the desktop/laptop version (prefer the classic desktop look) it pops up that the driver is available but when I go to activate it, after giving my password for permission, it shows the keys symbol at the top taskbar for a brief second then it (keys symbol) just disappears and it never activates the driver.
Does the same thing when I find the driver by going to System->Administration->Hardware Drivers

Must be a bug somewhere since it is working fine on the netbook remix version, like I said.

Everything else and the installation itself went fine. It's even running on my wired connection just fine and I've downloaded several apps from the repos already. Wireless connection is the only issue I can see.

Here is a pretty good description of what to do, it can be done from the install CD.

You need just to install kernel-headers of respective kernel version you have and then reinstall bcmwl-kernel-source and everything will work!

Also worked for Lucid (10.04) with a BCM4312:

$ lspci | grep Network
