    Re: Unable to activate wireless on ThinkPAD E570 with Loki 0.4.1

    Hi Evassilyev! I have the same problem. I bought a Lenovo Thinkpad E470 the other day and the wifi was not available. I have followed your guide above and downloaded the driver directory from https://minhaskamal.github.io and unpacked the zip-file. However, I do not understand what you mean in 3) "Change the Makefile. Line "export TopDIR ?= ..." to export "TopDIR ?= PATH TO EXTRACTED DIRECTORY".". Can you please describe this in another way? I cannot find the words export TopDIR?= anywhere. Thanks!

    It seems to me that a new upstream driver still doesn't support it. Isn't it that, am I missing something?
    Hi,
    I bought a Lenovo Thinkpad E470 for a couple of months and my wifi did not work either. I have followed the guide in the thread:

    export TopDir ...
    make
    sudo make install

    but when i type the command

    modprobe -a 8821ce

    I get the following error message:

    "modprobe: ERROR: could not insert '8821ce': Required key not available

    did modprobe work for you or how did you solve this key-problem?

    Thanks in advance!
    Best,
    Gustaf

    You need to go into BIOS/UEFI settings and disable Secure Boot for third party modules to load

    Doesn't work, make says linux/sched/signa.h doesn't exist

    This solution works with kernel 4.15!
    I've tried with 4.13 and failed to compile, throwing time_setup error!
    thanks,
