Unable to activate wireless on ThinkPAD E570 with Loki 0.4.1

[gusmagna]

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!

Solution of installing driver rtl8821ce from Endlessm repo worked for me too on my Thinkpad E470 and now WiFi just works.

However I'm still having problems with Bluetooth, it simply doesn't start so I can't see other BT devices.

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,
