My WiFI disconnected once again just a minute ago and here's what I found in dmesg right after it disconnected $ dmesg [13868.961515] cfg80211: Calling CRDA to update world regulatory domain [13868.967287] cfg80211: World regulatory domain updated: [13868.967297] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [13868.967303] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [13868.967308] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [13868.967311] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [13868.967314] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [13868.967317] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [13868.967796] cfg80211: Calling CRDA for country: RU [13868.970836] cfg80211: Regulatory domain changed to country: RU [13868.970840] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [13868.970842] cfg80211: (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm) [13868.970844] cfg80211: (5735000 KHz - 5835000 KHz @ 20000 KHz), (N/A, 3000 mBm) [13871.118092] cfg80211: Calling CRDA for country: RU [13871.123036] cfg80211: Regulatory domain changed to country: RU [13871.123041] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [13871.123045] cfg80211: (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm) [13871.123047] cfg80211: (5735000 KHz - 5835000 KHz @ 20000 KHz), (N/A, 3000 mBm) [13876.690454] cfg80211: Calling CRDA to update world regulatory domain [13876.692717] cfg80211: World regulatory domain updated: [13876.692720] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [13876.692722] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [13876.692723] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [13876.692724] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [13876.692725] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [13876.692726] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [13876.692841] cfg80211: Calling CRDA for country: RU [13876.694730] cfg80211: Regulatory domain changed to country: RU [13876.694732] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [13876.694734] cfg80211: (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm) [13876.694735] cfg80211: (5735000 KHz - 5835000 KHz @ 20000 KHz), (N/A, 3000 mBm) [13878.828279] cfg80211: Calling CRDA for country: RU [13878.833279] cfg80211: Regulatory domain changed to country: RU [13878.833288] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [13878.833292] cfg80211: (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm) [13878.833296] cfg80211: (5735000 KHz - 5835000 KHz @ 20000 KHz), (N/A, 3000 mBm) ____________________________________________________
I'm not sure what is happening and how to fix this. Any helpful advice would be really appreciated. -- 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/1379524 Title: Weak wifi signal and bluetooth missing firmware Status in “bcmwl” package in Ubuntu: Confirmed 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). 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".
