    Re: Wireless does not work Broadcom BCM57785

    I'm curious about the errors and warning messages on the syslog.
    Please see here: http://askubuntu.com/questions/26230...nager-conflict
    Therefore, if you use network manager (fine in simple set-ups only), then install dnsmasq-base, but not dnsmasq.
    Let's see which you have installed and try to recify it.
    Code:
    sudo dpkg -s dnsmasq
    sudo dpkg -s dnsmasq-base
    In my simple system, using NM, I have dnsmasq-base and not dnsmasq.

    Re: Wireless does not work Broadcom BCM57785

    Hello There, sorry for the delay!

    For sudo dpkg -s dnsmasq:
    Code:
     Package `dnsmasq' is not installed and no info is available.
    Use dpkg --info (= dpkg-deb --info) to examine archive files,
    and dpkg --contents (= dpkg-deb --contents) to list their contents.

    For sudo dpkg -s dnsmasq-base:
    Code:
     Package: dnsmasq-base

    It'S same configuration as you have, right?

    Re: Wireless does not work Broadcom BCM57785

    It is the same configuration and, as far as I know, correct configuration. As for the errors in the syslog, let's do some housekeeping first and see if it helps. We have established that brcmsmac is correct for your Ubuntu version and your 14e4:4727 device. Let's remove the wl driver:
    Code:
    sudo apt-get remove --purge bcmwl-kernel-source
    Since your wireless seems to be working as expected, aside from the syslog message, wait until you would otherwise reboot and then look at the logs again:
    Code:
    cat /var/log/syslog | grep -e wl -e 80211 -e etwork | tail -n20
    Is the message gone? Better? Worse?

    I saw this: https://bugs.launchpad.net/ubuntu/+s...r/+bug/1047221
    This bug was fixed in the package network-manager - 0.9.6.0-0ubuntu6
    Which do you have?
    Code:
    sudo dpkg -s network-manager

    Re: Wireless does not work Broadcom BCM57785

    Hello there!

    I have removed the "bcmwl-kernel-source" and this is the syslog output:

    Code:
    volkan@magnets:~$ cat /var/log/syslog | grep -e wl -e 80211 -e etwork | tail -n20
    Dec  2 16:33:30 magnets kernel: [23383.805002] ieee80211 phy0: wl0: ampdu tx phy error (0x20)

    volkan@magnets:~$
    Also, it seems that I have a previous version of the network-manager:
    Code:
    volkan@magnets:~$ sudo dpkg -s network-manager

    Description: network management framework (daemon and userspace tools)
     NetworkManager is a system network service that manages your network devices
     and connections, attempting to keep active network connectivity when

     devices, and provides VPN integration with a variety of different VPN
     services.
     .
     This package provides the userspace daemons and a command line interface to
     interact with NetworkManager.
     .
     Optional dependencies:
      * policykit-1: Required for reading and writing system connections.
      * ppp: Required for establishing dial-up connections (e.g. via GSM).
      * avahi-autoipd: Used for IPv4LL, a protocol for automatic Link-Local IP
        address configuration.

    And it seems that with my sources I still don't have the new network-manager version:

    Re: Wireless does not work Broadcom BCM57785

    After doing so, does your wireless still work correctly? Are the dnsmasq errors gone?
    Code:
    cat /var/log/syslog | grep dnsmasq
