    Wireless-N 1030 disconnecting periodically

    Recently I've moved from 13.10 to 14.04 and I've encountered issue with wifi. It's periodically disconnecting without any reason. Here I enclose output from http://ubuntuforums.org/showthread.p...5#post12350385

    I have to mention that I've already try
    Code:
    sudo modprobe -rv iwlmvm
    sudo modprobe -v iwlwifi bt_coex_active=N swcrypto=1 11n_disable=1
    sudo modprobe -v iwlmvm power_scheme=1
    But it didn't help

    Re: Wireless-N 1030 disconnecting periodically

    Hi przemek4, Welcome to the forums!

    How often does it disconnect? Does it happen in a running session or after a sleep/suspend etc.?

    The correct sequence (sequence is very important, or it won't work!) of commands you tried is -
    Code:
    sudo modprobe -rv iwldvm
    sudo modprobe -v iwlwifi bt_coex_active=N swcrypto=1
    sudo modprobe -v iwldvm
    Note that I have used "iwldvm", not "iwlmvm" which you used in your commands. This is because your system is not using the "iwldvm" driver, not "iwlmvm", and the iwldvm driver offers no parameters for us to try. I also didn't use the "11n_disable=1" parameter with "iwlwifi" driver, because it limits the speed to 54 Mbps and so should be tried only if necessary. We may try it later if initial attempts to fix the issues fail.

    Also note that the above commands enforce the parameters only temporarily, and they will be reset to defaults on next boot or after a driver reload (without parameters).

    If the suggested commands in correct sequence don't seem to help, please follow the instructions in this post to download and run 'wireless_script' (experimental version) and post back the report it generates : http://ubuntuforums.org/showpost.php?p=13024222

    Re: Wireless-N 1030 disconnecting periodically

    It disconnects ~ every hour. It's happen during running session.
    I've applied it
    Code:
    sudo modprobe -rv iwldvm
    sudo modprobe -v iwlwifi bt_coex_active=N swcrypto=1
    sudo modprobe -v iwldvm
    but as a result I completly cannot connet.

    I know that this changes are temporary so I've reboot my laptop and run 'wireless_script'. Here is output

    Did you get any error messages while running above commands? Please retry, and post them if there are any.

    Additionally, try setting "IPv6" to "Ignore" in network manager.

    Also try channels 1 or 11 in the router/access-point. Currently it is using channel 6 which is fine, but 1 or 11 usually offer better signal quality.

    Another thing to check in the router is the frequency band. If it is set to automatic 20/40 MHz mixed mode, try fixing it to 20 MHz mode. Reboot the router after saving any changes.

    With the above changes applied, please run the script again and post back the new report so that I can see the status with those changes.

    Re: Wireless-N 1030 disconnecting periodically

    Here is output of this
    Code:
    sudo modprobe -rv iwldvm
    sudo modprobe -v iwlwifi bt_coex_active=N swcrypto=1
    sudo modprobe -v iwldvm
    Code:
    przemek@fox:~$ sudo modprobe -rv iwldvm
    [sudo] password for przemek: 
    rmmod iwldvm
    rmmod mac80211
    rmmod iwlwifi
    rmmod cfg80211
    //Here NetworkManager shows 'Disconnected'
    przemek@fox:~$ sudo modprobe -v iwlwifi bt_coex_active=N swcrypto=1
    insmod /lib/modules/3.13.0-29-generic/kernel/net/wireless/cfg80211.ko 
    insmod /lib/modules/3.13.0-29-generic/kernel/drivers/net/wireless/iwlwifi/iwlwifi.ko bt_coex_active=N swcrypto=1
    //Here NetworkManager shows 'Disconnected - you are now offline'
    przemek@fox:~$ sudo modprobe -v iwldvm
    //Here NetworkManager is trying to connect. But he can't connect and show message 'Disconnected'.
    I added comments including NetworkManager behave after each instruction.

    In a moment i will post script output with changes applied on router.

    Re: Wireless-N 1030 disconnecting periodically

    Please post it in a new post, editing above one to add the report won't highlight your post in my search results and I won't notice it.

    It seems you left out some of the lines from the output by the way. The report should give us the complete picture.

    Re: Wireless-N 1030 disconnecting periodically

    I wanted to see the report with the parameters applied, so not all the changes were applied while running the script as is evident here -

    Half/incorrect actions are no actions in our field . But moving forward..

    ..I hope the following is from your manual toggling of wifi switch, not happening automatically by itself -

    Let's apply some parameters permanently and see if they help or cause problems. Please run the following code in the terminal -
    Code:
    echo "options iwlwifi bt_coex_active=N swcrypto=1" | sudo tee -a /etc/modprobe.d/iwlwifi.conf
    Then reload the driver -
    Code:
    sudo modprobe -rv iwldvm
    sudo modprobe -v iwldvm
    And check -
    Code:
    grep -R [[:alnum:]] /sys/module/iwl*/parameters
    Does it show "....bt_coex_active=N" and "...swcrypto=1" among other things? If yes, how is the wireless behaving? After a reboot?
    Varun
    Help others by marking threads as [SOLVED], if they are. (See how)
