[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash
Hi again, this took some time. I had to dig up a Windows 7 Rescue CD from somewhere, change my BIOS settings to activate legacy support (otherwise it would not boot), then start the BIOS update utility. Those were some tense 30 seconds. Afterwards, it rebooted into Windows, which I exited, rebooting again only to find out that either the Windows or the BIOS update had somehow mangled my grub partitions. With a vivid USB stick, I was able to make it boot again. Long story short, the error reappeared promptly. So, now I'm on 8DCN40WW (and we can probably remove the BIOS-outdated tag). I'm going to do some more testing, perhaps upgrading to vivid. -- 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/1415880 Title: 14e4:4365 bcmwl-kernel source: fix for null pointer crash Status in bcmwl package in Ubuntu: Incomplete Bug description: The bcmwl package as of now misses one patch for a bug that occurs with BCM43142 and possibly other broadcom chipsets that will look like random disconnects, poor wifi signal and kernel warnings, See also #1379524.

This is a MacBook Pro Retina 1st Generation 3) What is expected to happen is when one uses the bcmwl-kernel-source package in 14.10, it works on both 2.5Ghz and 5Ghz. 4) What happens instead is after upgrading to saucy or any newer release and installing bcmwl-kernel-source =6.30.223.30+bdcom- 0ubuntu1 it fails to find any 5GHz networks and connections on 2.5GHz are unstable. Unfortunately, while b43 does detect the chip, it only uses 2.4GHz and it has very slow data rates and connection drops. WORKAROUND: This chip is working perfectly fine on 2.5GHz and 5GHz using version 6.20.155.1+bdcom-0ubuntu6 of the driver. Downgrading the machine to kernel 3.8.x and bcmwl-kernel-source 6.20.155.1+bdcom-0ubuntu6 (both from raring) makes the chip work again.

[Kernel-packages] [Bug 1379524] Re: 14e4:4365 Weak wifi signal
There is a patch for the driver on http://pastebin.com/pATazP6K – found it through https://aur.archlinux.org/packages/broadcom-wl/ I've applied the patch on my Lenovo Z510 (which also has a BCM43142 chip) using dkms (copied the patch into /usr/src/bcmwl-…/patches, edited the dkms.conf, adding the patch name, called dkms common-postinstall) and since then the wifi has been rock solid. @Christopher M.

[Kernel-packages] [Bug 1405915] Re: Broadcom sta driver not working correctly on BCM43142 - low signal recieved
Also affects Lubuntu Utopic Unicorn (and incidentially all other distros with a =3.16 kernel I've tried). There is a patch on the arch linux wiki that seems to solve the problem (At least all long downloads I started last night have finished successfully). Here is the link to the arch linux bug tracker: https://aur.archlinux.org/packages/broadcom-wl/ And here is the link to the patch: http://pastebin.com/pATazP6K The solution involves the following steps: * copying the patch to /usr/src/bcmwl-$(version)/patches/0020-null-pointer-crash.patch * adding the patch into the /usr/src/bcmwl-$(version)/dkms.conf file (there are other patches referenced, just add it after the last one * running dkms build bcmwl-$(version) $(uname -r) (this should re-install the module) * rebooting the system -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bcmwl in Ubuntu. https://bugs.launchpad.net/bugs/1405915 Title: Broadcom sta driver not working correctly on BCM43142 - low signal recieved Status in bcmwl package in Ubuntu: Confirmed Bug description: 1) The release of Ubuntu you are using, via 'lsb_release -rd' or System - About Ubuntu mcarmen@matri:~$ lsb_release -rd Description: Ubuntu 14.04.1 LTS Release: 14.04 2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center mcarmen@matri:~$ apt-cache policy bcmwl-kernel-source bcmwl-kernel-source: Installed: 6.30.223.141+bdcom-0ubuntu2 Candidate: 6.30.223.141+bdcom-0ubuntu2 Version table: *** 6.30.223.141+bdcom-0ubuntu2 0 500 http://archive.ubuntu.com/ubuntu/ trusty/restricted amd64 Packages 100 /var/lib/dpkg/status 3) What you expected to happen 4) What happened instead I have just installed Ubuntu on my laptop with a BCM43142 card.

With my other devices, phone, tablet and in windows 8.1 I don't have this issue, and I can easily connect to them.
