I have an hp and BCM43142, Ubuntu 16.04, everything updated. I have bcmwl-kernel-source. The one available in additional drivers.

The internet works for few hours then it stops working, I'll have to log out and log in when that happens and sometimes, I must restart.

my blacklist.conf. I tried to reinstall the driver, which presumably rebuilds it and it didn't work. I tried b43-framework and it didn't work. Isn't there a more reliable driver offered by broadcom or hp?

The output of lspci -knn | grep Net -A2 is

 lspci -knn | grep Net -A2

  • @Pilot6 please check the question – Lynob Sep 09 '16 at 13:03
  • The driver is correctly installed. This must be some hardware problem, or a problem with this driver. I have no suggestions except replacing the wireless adapter. – Pilot6 Sep 09 '16 at 13:04
  • Well havent happened to me yet... – hellozee Sep 09 '16 at 13:07
  • @Pilot6 if the issue cant be solved im gonna have to reinstall windows 10 on the pc, as much as I hate it, it worked with bcm – Lynob Sep 09 '16 at 13:11
  • Try broadcom-sta-dkms instead of bcmwl-kernel-source. It looks like it is a new driver. – Pilot6 Sep 09 '16 at 13:15
  • @Pilot6 seems to have worked, will have to test drive it for 2 days and ill report back – Lynob Sep 09 '16 at 13:57
  • @still the same problem, disconnecting every now and then – Lynob Sep 10 '16 at 18:17
  • I exactly have the same problem with my Pavilion15, it seems this BCM43142 chip is problematic, as it is described in the driver of bcmwl-kernel-source: Description: Broadcom 802.11 Linux STA wireless driver source This package contains Broadcom 802.11 Linux STA wireless driver for use with Broadcom's BCM4311-, BCM4312-, BCM4313-, BCM4321-, BCM4322-, BCM43224-, and BCM43225-, BCM43227- and BCM43228-based hardware. you see there is no bcm43142 listed – Amir-Mousavi Jun 07 '17 at 12:50
