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. -- 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
