I had a lot of troubles for making my 5Ghz channel visible to my Broadcom BCM4360 (including reinstallation of the drivers). Now, I can see all 5Ghz wifi networks that works ONLY on low channels (I guess <100). However, I cannot connect to 5Ghz wifi network - even though it started authentication, completed it and then - no connection. Moreover, connecting to 2,4 GHz network is painful as I got very low speed internet connection here - maximum is about 3-5 mbps on speedtests, sometimes it is not even 1 mbps. I tried following steps:

  • Reinstalling drivers
  • Installing wicd (it is slower than network-manager though after installation)

  • Blocking IPv6 (kind of, I used this):

    sudo vim /etc/gai.conf

and uncommented:

precedence ::ffff:0:0/96  100

iwlist output:

wlp3s0    32 channels in total; available frequencies :
      Channel 01 : 2.412 GHz

      Channel 102 : 5.51 GHz
      Channel 104 : 5.52 GHz
      Channel 106 : 5.53 GHz
      Channel 108 : 5.54 GHz
      Current Frequency:2.422 GHz (Channel 3)

My ifconfig:

wlp3s0    IEEE 802.11  ESSID:"my_wifi_24"  
      Mode:Managed  Frequency:2.422 GHz  Access Point: 04:92:26:3A:93:F8

      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
      Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Is there something I can do about it? I have also looked for dmesg, but the output shows my wlp3s0 card in IPv6:

[  797.133189] IPv6: ADDRCONF(NETDEV_UP): wlp3s0: link is not ready
[  797.290173] IPv6: ADDRCONF(NETDEV_UP): wlp3s0: link is not ready

[  837.013071] IPv6: ADDRCONF(NETDEV_CHANGE): wlp3s0: link becomes ready

Please note that I also have built-in network card wlp2s0 that appears in dmesg like that:

[  980.012074] wlp2s0: deauthenticating from 04:92:26:3a:93:f8 by local choice (Reason: 3=DEAUTH_LEAVING)

My arch is x64,kernel 4.15.0-47-generic and I am using Xubuntu

Update: I have installed the correct driver from the driver table provided in the other topic about broadcom

Update 2: Adding output of commands:

 lspci -knn | grep -A4 -i "Network controller"

out:

and: 

sudo lshw -class network
