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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bcmwl in Ubuntu. https://bugs.launchpad.net/bugs/1595765 Title: Wifi drivers all fail to build [error: ‘IEEE80211_BAND_2GHZ’ undeclared here] Status in bcmwl package in Ubuntu: Confirmed Status in broadcom-sta package in Ubuntu: Confirmed Status in rtl8812au package in Ubuntu: Confirmed Bug description: error update for kernel 4.7 RC 3 ProblemType: Package DistroRelease: elementary 0.4 Package: bcmwl-kernel-source 6.30.223.248+bdcom-0ubuntu8 [origin: Ubuntu] Uname: Linux 4.6.2-040602-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 DKMSKernelVersion: 4.7.0-040700rc3-generic Date: Thu Jun 23 22:03:59 2016 DuplicateSignature: dkms:bcmwl-kernel-source:6.30.223.248+bdcom-0ubuntu8:/var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/src/wl/sys/wl_cfg80211_hybrid.c:237:12: error: ‘IEEE80211_BAND_2GHZ’ undeclared here (not in a function) InstallationDate: Installed on 2016-06-14 (9 days ago) InstallationMedia: elementary OS 0.4 "Loki" - Daily amd64 (20160613) PackageVersion: 6.30.223.248+bdcom-0ubuntu8 RelatedPackageVersions: dpkg 1.18.4ubuntu1.1 apt 1.2.12~ubuntu16.04.1 SourcePackage: bcmwl Title: bcmwl-kernel-source 6.30.223.248+bdcom-0ubuntu8: bcmwl kernel module failed to build UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1595765/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
