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".
