Error in driver for RTL8821CE

Error in driver for RTL8821CE

[Cristian Llanos]

Hi, my name is Cristian, I'm writing from Chile

I'm trying to install the driver for my RTL8821CE card. I'm following
the instructions from the repo https://github.com/lwfinger/rtw88 (I
took the email from there) but when I try to run the "make" command, I
get the following error:

/home/cristian/Downloads/realtek_drivers/rtw88/main.c: In function
‘rtw_core_init’:
/home/cristian/Downloads/realtek_drivers/rtw88/main.c:1623:2: error:
implicit declaration of function ‘tasklet_setup’
[-Werror=implicit-function-declaration]
 1623 |  tasklet_setup(&rtwdev->tx_tasklet, rtw_tx_tasklet);


this is the output from "sudo lshw -C network" and the full log of the error.

You need to do a git pull. The missing tasklet_setup was fixed on Sep. 26.

Re: Error in driver for RTL8821CE

[Cristian Llanos]

Larry thanks a lot for your response, and you were right about the git
pull, the code worked just fine.

But i'm still unable to connect my laptop to the internet. I made:

$ git pull
$ make
$ sudo make install (everything ok!)
And then, reboot.

But now i go to  the Settings panel (Ubuntu 20.04.1 LTS) and i'm still
unable to connect.

Let me show you some logs:

May I still need to do something else?

Thanks Larry for your time.

The drivers look OK.

Try the following commands:

iw dev | grep Interface
sudo iw dev XXXXX scan | egrep "signal|SSID"

Replace the XXXXX with the device name listed on the "Interface" line following 
the first command. Post the output of the second command and indicate which SSID 
is from your AP.

That means that it has not created a wireless interface.

Does the output of the dmesg command show any information?

Yes it does. The last lines are strange, missing a country code?
