WiFi does not work

[Maximil]

sorry for my English
I have a problem with wifi. I do not get any option to connect to a network, only usb wire or the network wire allows me to access. Use Linux Mint 18.1 Serena 64-bit Try several things but without success. I know that the problem is because of the driver that I can not install correctly. data,
they are url to images:

placing the command "inxi -Fxzc0" in the network part I get this

I do not know if it is enough information with the things that it offers, in any case if it is needed more they ask me. Greetings, I hope that someone can help me.

Have you tried what is posted in viewtopic.php?f=53&t=263651&p=1428802&h ... 3#p1429224

Thanks, I was testing the things in that post, I currently have the kernel

Linux 4.4.0-116-generic

I still do not walk, Now Ethernet doesn't work either.
Could you explain me a little more how to put the kernel, I'm a little new. Thank you

I managed to place the kernel with the Linux version 4.13.0-36-generic.
but when I run these commands

Code: Select all

git clone -b 4.10-down https://github.com/jeremyb31/rtl8723de.git
sudo dkms add ./rtl8723de
sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414

get these errors

Code: Select all

maxi@maxi-HP ~ $ git clone -b 4.10-down https://github.com/jeremyb31/rtl8723de.git
fatal: destination path 'rtl8723de' already exists and is not an empty directory.
maxi@maxi-HP ~ $ sudo dkms add ./rtl8723de

Error! DKMS tree already contains: rtl8723de-5.1.1.8_21285.20171026_COEX20170111-1414
You cannot add the same module/version combo more than once.
maxi@maxi-HP ~ $ sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414

Kernel preparation unnecessary for this kernel.  Skipping...

Building module:
cleaning build area....
'make' all KVER=4.13.0-36-generic....(bad exit status: 2)
Error! Bad return status for module build on kernel: 4.13.0-36-generic (x86_64)
Consult /var/lib/dkms/rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414/build/make.log for more information.

the first two errors is normal because I had already lowered them, but at the last as I fix it?

See if it worked in the 4.4 kernel as there are 2 versions of the source code, one for kernels 4.10 and older, and one for 4.11 and newer, the version you have should work in 4.4 but not the 4.13

You should also check UEFI/BIOS settings to see that Secure Boot is disabled

Well that part I was missing, I could already achieve Thank you very much, you are a teacher!
Thanks again, regards
