Title:
14e4:4365 Weak wifi signal
Status in bcmwl package in Ubuntu:
Expired
Bug description:
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).
The exact device name:
08:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)
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".
