Network controller Broadcom BCM4312 802.11b/g fails in karmic

[Alex Muntada]

Binary package hint: linux-image-2.6.30-8-generic

This wifi network controller doesn't work with latest karmic kernel (2.6.30-8-generic), however it does when booting older jaunty kernel (2.6.28-11-generic) on my HP mini.

The wl module is loaded in 2.6.28-11-generic:

wl: module license '' taints kernel.
wl 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
wl 0000:01:00.0: setting latency timer to 64

However, it does not in 2.6.30-8-generic.

I see exactly the same on my IdeaPad S10e

Just noticed Bug #381678
So installed bcmwl-kernel-source from Synaptic Package Manager, rebooted and now have wireless working

[Chris Wayne (cwayne)]

I'm seeing the same issue, though bcmwl-kernel-source is already installed

[Alex Muntada (alex.muntada)]

Installing bcmwl-kernel-source solved the problem for me too.

[Tom Haddon (mthaddon)]

Chris, try reinstalling bcmwl-kernel-source - it was installed already for me too, "sudo apt-get install --reinstall bcmwl-kernel-source" and a reboot seemed to do the trick for me.

The driver seems to work in Karmic with the latest kernel. I'm closing this bug report.

[Yotam Benshalom (benshalom)]

I experience the same issue with dell xps 1340.
In "Hardware Drivers" it says: Broadcom STA wireless driver, this driver is activated but not currently in use.
lspci gives:
06:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01).
Installing re-installing bcmwl-kernel-source and rebooting does not help.
Installing bcmwl-modaliases does not help.
Making sure in BIOS that the special wireless key is allocated only to wlan and using it does not help.
Wireless work in Win7.
Any advice? Where can I look and what more info can I give?

[Yotam Benshalom (benshalom)]

After a night's sleep it began to work. A miracle, and a bug set again to invalid. Hooray!

Hi Yotam thanks for your work on this. It's not yet clear to me how I can take advantage of this fix. I am new to Linux, and I have never had the Jaunty version on this (new HP mini 110) machine. Maybe the fix will be included in the next update of Ubuntu Netbook?

[marty pain (hutchinsteve)]

Just to clarify, is this a fix to get the propriety drivers to work correctly, or is this a work around so the propriety drivers are not needed?

Quite new to this, so just wanted to make sure.

Thanks

[boris8 (plf)]

I think it's the former. I say this because the drivers seem to work for folks who had Jaunty.

Installing bcmwl-kernel-source solved the problem for me too.

I'm marking this as wont-fix as karmic is lo nolger supported.
