The notebook in the title runs a dual boot with said Ubuntu version 14.04 and Windows 7.
After trivially installing drivers on windows, the wireless device works splendidly.
On Ubuntu however, installing drivers and rebooting does not help that much. I followed this awesome guide: Installing Broadcom Wireless Drivers. This helped a little in understanding, but didn't help regarding my issue.
One of the problems might be that I did not start with a fresh system.
First thing I then did was:
sudo apt-get purge firmware-b43-installer sudo apt-get purge bcmwl-kernel-source
Starting from this point I know the device and the PCI ID of the wireless device. I can see the device in lspci only:
$ lspci -nn -d 14e4: 24:00.0 Network controller : Broadcom Corporation BCM43228 802.11a/b/g/n [14e4:4359]
If the lsusb output helps:
$ lsusb Bus 002 Device 003: ID 0a5c:21e1 Broadcom Corp. HP Portable SoftSailing
As mentioned in the guide above (I consulted the table with packages for certain PCI IDs) I then tried to install bcmwl-kernel-source again:
$ sudo apt-get install bcmwl-kernel-source
The important error:
Building initial module for 4.4.0-31-generic ERROR: Cannot create report: [Errno 17] File exists: '/var/crash/bcmwl-kernel-source.0.crash' Error! Bad return status for module build on kernel: 4.4.0-31-generic (i686) Consult /var/lib/dkms/bcmwl/126.96.36.199+bdcom/build/make.log for more information. modprobe: ERROR: ../libkmod/libkmod-module.c:809 kmod_module_insert_module() could not find module by name='wl' modprobe: ERROR: could not insert 'wl': Function not implemented modprobe: ERROR: ../libkmod/libkmod-module.c:959 command_do() Error running install command for wl modprobe: ERROR: could not insert 'wl': Operation not permitted update-initramfs: deferring update (trigger activated) Trigger für initramfs-tools (0.103ubuntu4.10) werden verarbeitet ... update-initramfs: Generating /boot/initrd.img-4.4.0-31-generic
By now it's clear 'wl' is missing, but I don't really know how to get it into the system.
Another information: The notebook comes with a WiFi-Button above the keyboard which I pressed thoroughly - I can enable/disable Bluetooth connection with this, but it has no effect (yet) on WiFi.
modprobe wl obviously does not work. The exact same errors will be shown when installing bcmwl-kernel-source.
rfkill list does only show
0: hci0: Bluetooth Soft blocked: no Hard blocked: no
What besides my lack of insight can be wrong? After removing firmware-b43-installer and bcmwl-kernel-source can there be some other package be interfering in the process? Any further ideas on making the wireless device working would be much appreciated!
