I am using the Asus PCE-AC68 wireless card which uses the Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03) chipset. The bcmwl-kernel-source driver is installed and connecting typically works for a few minutes after logging in before the connection drops and the network-manager keeps asking me for the password over and over. Sometimes it works for a few seconds/minutes and then drops again.

I've tried turning the power management off with "sudo iwconfig power off", but as soon as I try to connect to a network, it turns back on again.

Distro: Ubuntu Studio 16.04.1

I've tried:

  • Setting ipv6 to ignore
  • Adding auto wlp6s0 iface wlp6s0 inet dhcp wireless-power off to /etc/network/interfaces
  • sudo iwconfig wlp6s0 power off

iwconfig gives the following output:

$ iwconfig
lo        no wireless extensions.

wlp6s0    IEEE 802.11abg  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:on


enp3s0    no wireless extensions.

ifconfig entry for wlp6s0:

wlp6s0    Link encap:Ethernet  HWaddr 1c:87:2c:b6:cf:93  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:139 errors:0 dropped:0 overruns:0 frame:612
          TX packets:227 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:19824 (19.8 KB)  TX bytes:34566 (34.5 KB)
          Interrupt:19

Any ideas as to what I could try next?

Cheers!

  • I have installed WICD and there seems to be improvement... Perhaps network-manager couldn't handle the repeater signals with the same SSIDs with this card (works on my laptop though)? – Erik Natanael Gustafsson Aug 11 '16 at 12:54

After a few days of uninterrupted network connectivity it seems like WICD works well as a workaround and that the problem lies with network-manager.
