Lenovo Thinkpad no WiFi under 18.3

[almilne]

Hi everyone,

I'm new to Linux and just finished setting up my new Thinkpad with Linux Mint 18.3 and now have the following problem. My wireless adapter seems to not be working. I assume it has something to do with a missing driver, but that's just a guess.
In the Driver Manager, there is just one slot about intel-microcode which I have ticked. The output of inxi -Fxz is

Try some of the ideas in this article from the Easy Linux Tips Project.

try this with a Ethernet connection.

Code: Select all

sudo apt-get install dkms git
git clone https://github.com/gnab/rtl8812au.git
sudo dkms add ./rtl8812au
sudo dkms install 8812au/4.2.2

It might be the case that this

Code: Select all

driver: r8169

is not quite right for your card. See: https://unixblogger.com/2016/08/11/how ... ted-guide/

Thank you for the tips, I think it pointed me in the right direction. I found this

Download driver directory from this repo:https://github.com/endlessm/linux/tr...less/rtl8821ce. You can do it by this link: https://minhaskamal.github.io/DownGi...less/rtl8821ce
Unpack zip archive.
Change the Makefile. Line "export TopDIR ?= ..." to export "TopDIR ?= PATH TO EXTRACTED DIRECTORY".
make
sudo make install
sudo modprobe -a 8821ce

I followed the described procedure, but I'm getting error messages in the 3rd step 'make'...

Do you have any suggestions?

[almilne]

Can anyone help me with my problem in the makefile?
This problem pops up several times for different thinkpads across several forums, but they all refer to the same solution, the one I quoted earlier.
It seems to have worked for those in the original threads though. Any idea on why it doesn't work for me?
Could this be a kernel version problem? Any help is much appreciated!

Thanks in advance.

PS: the driver for 8812au did not work, sadly..

EDIT: Also, the files this solution is referring to (under https://github.com/endlessm/linux/tree/ ... /rtl8821ce ) says "rtl8821ce: fix build for Linux-4.15". Does this mean it is for a later kernel version? My version is 4.13.

Kernel 4.15 will not be available in Mint until Mint 19. You can install it with a program called UUKU but it will be a vanilla kernel and not have any of the Ubuntu/Mint upgrades. And if you run into other problems with it it may be difficult to get help.
UUKU is found here:
https://www.omgubuntu.co.uk/2017/02/uku ... nel-ubuntu
Other than that kernel 4.15 is in Ubuntu 18.04 beta or daily releases now. it may be worth downloading and trying it out in live mode to see if the new kernel will fix your problem.

Thanks!
I will try this with the new kernel version.
