    Re: Thinkpad L540, Ubuntu 13.10, ThinkPad Wireless 2 x 2 BGN+BT 4.0: No Wi-Fi.

    Error! The dkms.conf for this module includes a BUILD_EXCLUSIVE directive which
    It actually says:
    Code:
    BUILD_EXCLUSIVE_KERNEL="3\.[58]\..*"
    I'm not sure (read: skilled enough to know) what that means; perhaps it means for kernels 3.5 through 3.8. You have 3.11. As I said, I compiled the tarball on my 3.11 system. It produces a few warnings but no errors. Whether the module it builds works sufficiently to drive the hardware I don't know as I haven't the device. If you'd like to try it:
    Code:
    sudo apt-get install build-essential linux-headers-generic
    Download this file to your desktop: http://netbook-remix.archive.canonic...sutton1.tar.gz Right-click it and select 'Extract Here.' Now back to the terminal:
    Code:
    cd ~/Desktop/oem-wireless-rtl-92ce-92se-92de-8723ae-88ee-8723be-92ee-dkms-0017.1016.2013~sutton1/oem-wireless-rtl-92ce-92se-92de-8723ae-88ee-8723be-92ee-0017.1016.2013~sutton1/driver
    You can probably get Tab to autocomplete.
    Code:
    make
    sudo make install
    sudo modprobe rtl8192ee

    It's working, finally!!!
    Probably driver compilation on my architecture was needed...

    I have the impression there are still some issues to be fixed. Now I'll install the distro and check carefully...

    Thanks a lot for your time and patience,

    Awesome! You have compiled the driver for your currently running kernel only. When Update Manager offers a new kernel, also known as linux-image, you must recompile:
    Code:
    cd ~/Desktop/oem-wireless-rtl-92ce-92se-92de-8723ae-88ee-8723be-92ee-dkms-0017.1016.2013~sutton1/oem-wireless-rtl-92ce-92se-92de-8723ae-88ee-8723be-92ee-0017.1016.2013~sutton1/driver
    make clean
    make
    sudo make install
    sudo modprobe rtl8192ee
    I suspect you will have helped quite a few searchers.

    Re: Thinkpad L540, Ubuntu 13.10, ThinkPad Wireless 2 x 2 BGN+BT 4.0: No Wi-Fi.

    Thank you both for working through this.

    short version: I got the wireless working using chili555's first instructions and the first deb file on a computer with 12.04 ubuntu and the 3.5 kernel.

    longer details: I just got a new t440p which has the same wireless controller as in this thread and I am using 12.04 with the 3.5 kernel. I took my HDD from an older computer and initially neither the ethernet nor the wireless worked when the old HDD was in the new computer. I then moved it back to the old computer to upgrade the kernel to 3.5 from 3.2 at which point the ethernet was recognized by the new computer. From there, I used your first batch of instructions (from the first page) with the first deb file you posted and that did the trick for wireless.

    Thanks!

    update: there were some issues upon further use -- the computer would freeze (screen would not change but keyboard and mouse wouldn't do anything, required reset by holding power button). This appears to have been related to power management of the wireless card which also had to be played around with. I added a script called wireless to /etc/pm/power.d which would turn of the power management using iwconfig (all this as per various suggestions elsewhere) -- this seems to be working so far.

    Wow, thanks chili555!
    I couldn't connect with my rtl8192ee; it was like Ubuntu didn't know what to do with the hardware. I have a fresh new install of Ubuntu 14.04 LTS, and by following your to download the oem....tar.gz file and rebuilding it per your directions above, it now works!

    I have been so frustrated because there are so many places that *seem* be be the right answer, but do not work for me!
    Thank you, thank you, thank you!

    Re: Thinkpad L540, Ubuntu 13.10, ThinkPad Wireless 2 x 2 BGN+BT 4.0: No Wi-Fi.

    Sadly, it was a short-lived victory. I had to re-install Ubuntu (14.04 LTS) - for an unrelated reason - and now when I go through the above procedure (downloading the oem... and doing the make & make install), I get a kernel panic when I do the
    Code:
    sudo modprobe rtl8192ee
    I am going to search through the forums some more & if I don't find anything else, I'm going to start a new thread for 14.04 LTS with RTL 8192EE.

    Meanwhile I'm going to get a USB wireless adapter. I'm tired of re-installing Ubuntu. Sigh...

    Re: Thinkpad L540, Ubuntu 13.10, ThinkPad Wireless 2 x 2 BGN+BT 4.0: No Wi-Fi.

    Followed solution by chili555 #11, things were looking good, but on the last instruction got a Kernel panic response (same as PurpleDiane #16). Response looks something like this:
    [ 14.247617] RIP [<ffffffffa0675c45>] rtl92ee_rx_query_desc+0x175/0xaa [rtl8192ee]
    [ 14.247638] RSP <ffff88021e203cd0>
    [ 14.254020] Kernel panic - not syncing: Fatal exception in interrupt
    [ 14.256297] drm_kms_helper: panic occurred, switching back to text console

    I tried to reboot, but Ubuntu gets me back to the screen with the above error. I can't even type anything.
    What to do now?

    Thanks!

    Can you interrupt the boot process and get to the GRUB menu and get to recovery mode? https://help.ubuntu.com/community/Grub2 If so, log in at the terminal with your user name and password. Then do:
    Code:
    cd ~/Desktop/oem-wireless-rtl-92ce-92se-92de-8723ae-88ee-8723be-92ee-dkms-0017.1016.2013~sutton1/oem-wireless-rtl-92ce-92se-92de-8723ae-88ee-8723be-92ee-0017.1016.2013~sutton1/driver
    sudo make uninstall
    If that works, then:
    Code:
    sudo reboot now
    I will look for the more recent method to build rtl8192ee and post it in a few minutes.

    EDIT: This was the thread I was referring to: http://askubuntu.com/questions/52339...rives-is-empty

    However, as you can see:
    Oh . When I use this way . My ubuntu was totally corrupt. Coming with a black screen writing kernel panic-not syncing fatal exception in interruption.
    I will keep looking, but, at this moment, I am unable to find any method to drive this device.

    Re: Thinkpad L540, Ubuntu 13.10, ThinkPad Wireless 2 x 2 BGN+BT 4.0: No Wi-Fi.

    Here is something else you both (all?) might try. With a temporary internet connection, do:
    Code:
    sudo apt-get update
    sudo apt-get install linux-headers-generic build-essential
    Download this file and drag and drop it to your desktop: https://www.kernel.org/pub/linux/ker...8-rc1-1.tar.xz Right-click it and select 'Extract Here.'

    Back to the terminal:
    Code:
    cd ~/Desktop/backports-3.18-rc1-1
    make defconfig-rtlwifi
    make
    sudo make install
    sudo modprobe rtl8192ee
    Report back if it works as expected; we will have one more step.

    chilli555, thank you so much for such a prompt response.
    As suggested, I tried to restart Ubuntu using the recovery mode, but it seems that the rebooting is stuck in "Loading Linux 3.13.0-39-generic ..." (so far 20+ minutes there)... I'll keep you posted of any progress.
    Thanks again!
