Tell me what to do.

[AZgl1800]

the first thing you need to do, is go back to your first post and please, purty please use the EDIT button.....
then

suck out the code for each of those commands,

then click on the code block above the editor, it looks like this </>, and paste all of that stuff into the Code Block section.

that way, we can read the individual sections in smaller, scrollable code blocks.

and leave at least 3 blank lines between those code block sections with your description of what you did.

here is an example of how it will look when you get it right, use the Preview button to see how you are doing.

Code: Select all

john@john-TP500LA ~ $ inxi -S
System:    Host: john-TP500LA Kernel: 4.15.0-30-generic x86_64 (64 bit) Desktop: Cinnamon 3.6.7
           Distro: Linux Mint 18.3 Sylvia
john@john-TP500LA ~ $ 

you can "highlight" certain words or phrases by using this code "[ c ]" in front of the phrase
and this code "[ /c ]" after the phrase....

that is how I showed the code symbols here...
do NOT add the " symbols, or the extra spaces, I had to do that to prevent the forum from acting on the codes.

[JeremyB]

In terminal do

Code: Select all

sudo apt install git build-essential
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install

Reboot and if wifi isn't working post results for

Code: Select all

dmesg | grep iwl

[AK25]

It didn't execute

Code: Select all

make defconfig-iwlwifi-public

the output is
make: *** No rule to make target 'defconfig-iwlwifi-public'. Stop.

[JeremyB]

Missed a command

Code: Select all

cd backport-iwlwifi
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install

[AK25]

Thank you. It worked. Now I dont have to use usb wifi dongle. Thanks a lot.

[JeremyB]

After a kernel update you will need to

Code: Select all

cd backport-iwlwifi
make clean
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install

[AK25]

What this will do?

[JeremyB]

The driver might not be fixed in the new kernel, if you install a new kernel and have no wifi, run those commands to install the driver in the new kernel

[AK25]

Code: Select all

sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config

Didn't work this time.
Shows
sed : can't read .config: No such file directory

[JeremyB]

That .config file should be there after make defconfig-iwlwifi-public is run
