14e4:4315 No wifi (BCM4312) with proprietary driver

Bug Description

Interface is not created.

Wifi worked perfectly in precise and also in quantal until some recent upgrades.

It was discovered that the proprietary driver was in use. This seems to have nothing to do with kernels. Once the proprietary driver was removed - the Wifi was fine.

Blessings,
Shahar

Shahar Or, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.

Dear Christopher,

I used:
linux-image-3.5.0-030500-generic 3.5.0-030500.201207211835 i386

Running this kernel, I had several problems besides the WiFi not working:
1. There was no boot animation - only the nice background color until the greeter.
2. The X resolution was lower than usual.
3. USB connected mouse doesn't work.

Can I further help?

Blessings,
Shahar

Oh, and the wired Ethernet adapter didn't have an interface created for it, either, in this kernel I tested.

Shahar Or, thank you for testing the mainline. Did this problem not occur in a prior Ubuntu release? As a potential WORKAROUND, does the proprietary driver work for you https://help.ubuntu.com/community/BroadcomSTA%28Wireless%29 ?

Christopher,

It used to work in precise and also in quantal up until some recent upgrades.

Thanks for the workaround. I've yet to try it.

Thanks,

Hi Shahar,

I see from your bug description that you are testing one of the upstream kernel builds. May I ask if you installed both the linux-image and linux-image-extra packages? You will need to have installed both for a complete kernel offering in Quantal. Thanks.

Shahar Or (mightyiam) wrote :

Thanks, Leann.

Now I'm testing the 3.5 upstream kernel build with the linux-image-extra included and I don't experience all those other issues.

The bug persists.

Shahar Or (mightyiam) wrote :

I've hit a breakthrough on this.

Once I removed the proprietary 'Broadcom STA ...' driver this issue was resolved.

So this isn't about kernels. And I did confirm this by testing some kernels.

This is about the presence of the proprietary driver that breaks support for the card.

Once I uninstalled it using the 'Software Sources' I had my interface back.

So there are two issues here. One is that the proprietary driver doesn't work. At least not in quantal for this card.

The other issue is that this proprietary driver was installed automatically in one of the quantal updates at one point. I didn't call for it, IIRC. And it would make sense that if I would have installed it by myself I would have remembered that I had and would have reverted back once I had no WiFi.

Thanks,
Shahar

BTW, I can't reinstall the proprietary driver using Software Sources because of Bug #1028388.

My laptop also uses the broadcom-sta driver as I have the bcm4312. I just tried the daily iso image for 12.10 and could load the broadcom-sta driver, however the nm-applet did not have any options for enabling wireless. I opened up terminal and checked iwconfig and it reported that there were no wireless drivers installed at all and this was after installing the driver. I tried searching for bugs about this, but have not seen anything similar as this does not seem to be related to the broadcom driver per se, but not sure if this should be a new bug yet. Please advise.

Justin Lane, could you please file a new report by executing the following in a terminal:

Hi,

I've just encoutered quite the same issue whith my laptop (Compaq CQ10) on Lubuntu 12.10. All was correct except I could'nt connect to network whith the wifi.

Kernel : 3.5.0-17-generic i686
Chipset : 01:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

To correct the problem i've installed the "firmware-b43-lpphy-installer" package and rebooted the computer.

The wifi work fine now.

Shahar Or, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc4

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

Christopher,

I don't care that the proprietary driver doesn't work because the free one seems to be working perfectly.

This bug does not affect me.
