Public bug reported:
On a fresh install of Ubuntu 14.04 on my new HP Pavilion 15-020ng with
Broadcom BCM43142 hybrid wifi/bluetooth chipset the official driver from
Broadcom does not work correctly. On 2.4 GHz the wifi signal is so low
that the connection is interrupted on a regular basis (network manager
shows 26 Mb/s), other devices (notebook, tablet) do have a normal signal
at the same position and even this laptop has a good signal with Windows
7 (Dual-Boot).
In addition, Bluetooth does not work because the driver reports missing
firmware but there does not seem to be official firmware available
anywhere.
The exact device name:
08:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n
[14e4:4365] (rev 01)
The 5 Ghz frequency seems to be not supported by the driver according to
the README file and does not work at all. My router is set to use
WPA2-PSK with AES, which is the only possible option besides WPA or
WPA/WPA2-mixed.
I am using the official wl driver that was installed by default, also
tried reinstalling via "sudo apt-get install bcmwl-kernel-source
--reinstall" without improvement and "sudo iwconfig wlan0 power off".
Also blacklisted b43, brcmsmac and bcma as suggested by "Linux
Wireless".
