    Inspiron 13 7000 Series disconnects from WIFI

    My wife's Dell has recently started diconnecting from WIFI. Every time she has either simply reconnect (as it asks for password again) or turn off/on wireless. I tried to follow some recommendations from this forum but it did not help. I am attaching the results of the wireless script and our router's setup in case someone could take a look.

    First, check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, I have better luck with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.

    If these changes are ineffective, reboot and let us see:
    Code:
    dmesg | grep iwl

    It is already set to WPA2-AES (as far as I can see from the router settings). I have set the channel width to 20MHz. Just in case I have run dmesg, see below.

    Still looks pretty normal until the last line. May we also see:
    Code:
    dmesg | grep 80211
    This is the first Intel 7265 device I've seen, so I am anxious to learn its peculiarities.

    I do note that the -8 version of the firmware loads, but modinfo suggests -7.

    That was an interesting quirk in the iwlwifi driver that took us a while to discover! The version of iwlwifi in Ubuntu 14.10 uses the -9 firmware; a possible solution may be to install the backported driver suite from kernel version 3.16+, but let's see if we can fix what we have before we throw it out and try something newer.

    Re: Inspiron 13 7000 Series disconnects from WIFI

    Once again, we see nothing remarkable that suggests a fault we can fix. I suggest we try the iwlwifi driver from kernel version 3.18. Please download this to your desktop: http://www.kernel.org/pub/linux/kern....18.1-1.tar.xz

    Right-click and select 'Extract Here.' Now, in the terminal:
    Code:
    sudo apt-get install linux-headers-generic build-essential
    cd ~/Desktop/backports-3.18.1-1
    make defconfig-iwlwifi
    make
    sudo make install
    We also need the firmware. In fact, the driver you just built suggests -9 but the official iwlwifi site suggests that for kernels 3.17 and above, -10 is used. Let's install both. Please get the 7265 files here: http://wireless.kernel.org/en/users/...lwifi#Firmware Downloads usually go to your Downloads folder. Right-click each and select 'Extract Here.' Now, in the terminal:
    Code:
    cd ~/Downloads/iwlwifi-7265-ucode-23.11.10.0
    sudo mv iwlwifi*  /lib/firmware
    cd ~/Downloads/iwlwifi-7265-ucode-25.228.9.0
    sudo mv iwlwifi-7265-9.ucode  /lib/firmware
    sudo chmod 644 /lib/firmware/iwl*
    Reboot and let us hear your report. We will probably have one additional step.

    Thanks a lot. I have followed all the steps. It works fine so far. Will report if there are still issues.

    shall I check if all the changes took effect?

    If it is working as expected, I doubt you need to; if you are curious, see what the version of the driver is:
    Code:
    modinfo iwlwifi
    It should be something like:
    version: backported from Linux (v3.18.1-0-g39ca484) using backports v3.18.1-1-0-g5e9ec4c
    And please tell us what firmware got loaded:
    Code:
    dmesg | grep iwl
    Glad it's working!
