Wifi drivers all fail to build [error: ‘IEEE80211_BAND_2GHZ’ undeclared here]

Status changed to 'Confirmed' because the bug affects multiple users.

it seems the package is incompatible with the 4.7 kernel, which it's shows when booted in it and trying to reinstall.

there is in issue open here:
https://github.com/longsleep/bcmwl-ubuntu/issues/17

I tried to build that version and after installing I got:

there is many errors in the log, probably needs quite some modification.
Feel happy to try and fix it, I really do not have the time at the moment

error updating kernel 4.7 RC 3

I fixed the issue and submitted a pull request:
https://github.com/longsleep/bcmwl-ubuntu/pull/18
you can find my fork here:
https://github.com/vgerris/bcmwl-ubuntu/
Just follow the instructions and it should work.

Does anyone know where to fix this upstream?
Happy to patch.

Please find the 64 build deb attached for convenience.

Greetings

What is the current status? Linux 4.7 has been released, and the bug remains, while there hasn't been any activity here for ~25 days.

I fixed the bug but I have issues getting it in place because there is no
official git I can make a pull request for. Will update soon

ok thanks, I hope it will be fixed before 16.10 is releases because it will use linux 4.8 by default.

Has someone reported this issue upstream to
1) Broadcom?
2) the Linux kernel bug tracker, preferably in a section dedicated to Broadcom wireless drivers?

A quick search doesn't show any trace of either. I'm not sure what the kernel/driver people could do, but it wouldn't hurt if they were aware.

Also, does the patched code still build with earlier kernel versions?

I have this issue with the 4.8. RC6 upstream kernel (http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8-rc6/).
I attached /var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/make.log

I installed kernel 4.8.6 and it's working normally for me

It worked for me on 4.8.10. Try this deb built by canonical :
https://launchpad.net/ubuntu/zesty/amd64/bcmwl-kernel-source/6.30.223.248+bdcom-0ubuntu11

I encountered this bug after installing linux-generic-hwe-16.04-edge on Ubuntu 16.04 LTS.

Installing the deb suggested by vgerris in comment #14 fixed the problem. The bcmwl kernel module built successfully for both the 16.04.1 kernel (kernel-4.4.0-53-generic-x86_64) and the HWE kernel (linux-generic-hwe-16.04-edge - kernel-4.8.0-30-generic-x86_64). Wireless connectivity with the new module works as before for both kernels. No issues noted after around 6 hours of use.

I recommend the fixed version of the bcmwl-kernel-source be backported to xenial since it seems to work well with both the stock kernel and the LTS enablement kernel. Alternatively, to avoid destabilizing existing LTS systems, release the updated version as part of the 16.04 HWE enablement stack. The 16.04.2 point release comes out not long from now and wireless should work with the updated kernel that will ship with it.

I have backported the august 42016 release (6.30.223.248+bdcom-0ubuntu9) to Trusty, and that source builds and works fine with the 4.7.2 stock kernel.

It also builds fine with 4.8.15 stock kernel. However, I get an oops when wl.ko is loaded, not in the bcmwl driver itself but in the cfg80211 driver, a null ptr dereference as far as I can see.

Does the fix discussed here address that issue too, or is that related to something else?

I see that wl.ko is being loaded on another laptop with an Intel wireless board, and there I'm not seeing any kernel oopses. Neither in cfg80211 which is also used by the iwl drivers.

I installed 4.8 hwe edge from the repositories on my 16.04 system (Macbook Pro with Broadcom 4331 card). I lost wireless.

I rebooted, made sure I was up to date, etc etc. Nothing in 4.8 would work. Anything 4.4.x would work fine though.

I received an error when installing via terminal much like the error in the original post. This gave me a lead which ultimately lead me here. Installing via GUI (system settings >> software and updates >> additional drivers) did not yield any sort of error.

In the end, nothing worked with getting wifi working again on 16.04.1 + BCM4331 + HWE Edge Kernel 4.8 -- until I downloaded the .deb Vincent linked in post 14 above. I was skeptical to try it as the version numbers of the .deb seemed to match what was in the repos when I searched Synaptic, but alas, I tried it. Immediately I reconnected to wifi on my 5ghz network. I installed it via dpkg -i in terminal, and the output looked cleaner.

Given I tried installing the 4.8 hwe edge kernel here on February 2nd and ran into this problem... yet 16.04.2 is due out within days... I raise the difficult question and can't help but to wonder if things are "ready". Otherwise I would anticipate an additional flurry of reported issues coming in relating to this topic.

@JaSauders: Their is a fix regarding the kernel 4.8 compatibility in the xenial-proposed repo. It just have not hit stable yet. The version that is compatible with 4.8 (hwe) kernel would be 6.30.223.271+bdcom-0ubuntu1~1.1

Can the maintainers please have a look at the following for rtl8812au 4.3.20,

https://github.com/diederikdehaas/rtl8812AU/tree/driver-4.3.20

It is working on my Ubuntu 16.10 and resolves the build issues with the current 4.3.14 dkms source.

Thanks iMac (imac-netstatz). I just installed the drivers from the github repo on 17.04 and it works.

Best I can tell there are no dedicated "maintainers" of wifi drivers. Just some people occasionally step in and provide fixes (and those people also work on many other things).

So... if anyone has the time, please step up and take ownership. Instructions for getting fixes into Ubuntu are here: https://wiki.ubuntu.com/StableReleaseUpdates

Same problem with rtl8812au-dkms_4.3.8.12175.20140902+dfsg-0ubuntu4_all.deb and 4.8.0-49 kernel.

The code referenced in comment #19 worked for me. Device is a Netis WF2190.
