    [/etc/modprobe.d/iwlwifi.conf]
    options iwlwifi 11n_disable=1
    It appears that an instruction you read is old enough that it was written, and therefor executed by you, before the file iwlwifi.conf was revised by default. Your /etc/modprobe.d/iwlwifi.conf file should read:
    Code:
    # /etc/modprobe.d/iwlwifi.conf
    # iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
    # microcode file installed on the system.  When removing iwlwifi, first
    # remove the iwl?vm module and then iwlwifi.
    remove iwlwifi \
    (/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
    && /sbin/modprobe -r mac80211
    options iwlwifi 11n_disable=1
    Please fix it with:
    Code:
    gksudo gedit /etc/modprobe.d/iwlwifi.conf
    Use nano or kate or leafpad if you don't have the text editor gedit.

    After doing so, reboot and let us see your wireless-info again.

    Thanks for the response. I updated the iwlwifi.conf as suggested. Please see the attached wireless-info.txt after the update.wireless-info.txt

    I wonder why we don't see the module iwldvm or else iwlmvm. I hoped the change you made might help. Let's check:
    Code:
    lsmod | grep -e iwl -e 80211
    Let's try this:
    Code:
    sudo modprobe iwldvm
    Any change? Errors? Warnings??
    Code:
    dmesg | grep iwl
    iwconfig

    I worked on a very similar case here: http://askubuntu.com/questions/67270...reless-ac-3165

    I suggest you try the rename steps. If it doesn't help, then, as the thread suggests, I'd install the 4.2 kernel.

    Please post back if you need assistance.

    Re: No wifi with Intel Dual channel 3165 wifi on HP Pavilion 15z and Ubuntu 15.04

    Thanks for the help. My wifi works on ubuntu 15.04 now.

    What i did to fix it:
    1. Downloaded the ucode for my Intel wifi device (3165) with 3.19+ kernel (https://wireless.wiki.kernel.org/_me...25.17.12.0.tgz) from https://wireless.wiki.kernel.org/en/...rivers/iwlwifi
    2. Renamed and copied the downloaded ucode files into /lib/firmware
    sudo cp Download/iwlwifi-7265D-12.ucode /lib/firmware/iwlwifi-3165-9.ucode
    sudo cp Download/iwlwifi-7265-12.ucode /lib/firmware/iwlwifi-3165-12.ucode
    3. Rebooted

    This works on the NUC 5CPYH with the 3165 as well on Xubuntu 14.04.

    Thanks a lot bud5!
    I had been reading many posts, including other suggesting to copy from 7265. But it was only your post w/ the exact link to version 12 of firmware 7265 that solved my problem. Previously I had tried w/ version 13 but it wouldn't work w/ kernel 3.19
