As mentioned by others, Wi-Fi connection files in system-connections directory have the interface MAC address included. This need to match your current setup hence the procedure is:
copy all files from old machine to new machine from/to directory:
/etc/NetworkManager/system-connections
sudo cp -Ri /etc/NetworkManager/system-connections /media/bruno/Elements/bruno-ubuntuPC/system-connections/
Now on the new PC:
change MAC address entry in each file from old MAC to new MAC. As root:
cd /etc/NetworkManager/system-connections
sudo sed -i -e 's///' *
Just in case, restart network manager:systemctl restart NetworkManager
service network-manager restart
In the end:
change permissions:
sudo chmod 0600 *
sudo chown root:root *
cd /etc/NetworkManager/system-connections
sudo sed -i -e 's/
Just in case, restart network manager:systemctl restart NetworkManager
service network-manager restart
In the end:
change permissions:
sudo chmod 0600 *
sudo chown root:root *
