Jeremy (wa113y3s) said : #2

Actually in terminal do one line at a time

sudo apt-get install git build-essential dkms
git clone https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6

Reboot and make sure Secure Boot is disabled in UEFI. This is an Ubuntu kernel bug

Jeremy (wa113y3s) said : #3

There is an issue with dkms.conf in that github repo so do

sudo apt-get install git build-essential dkms
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6

Can you help with this problem?
