Setting a Static IP in Linux with nmcli

If it uses NetworkManager:
cat /etc/netplan/01-network-manager-all.yaml :
# Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
Determine the Default Gateway:
Use the ip route command to find out the default gateway of your network, which is essential for configuring your static IP.
ip route | grep default | awk '{print $3}'
Setting a Static IP Address:
Replace "WifiName" with your actual connection name. Here’s how you can set a static IP address, gateway, DNS, and switch the method to manual:
nmcli con mod "WifiName" ipv4.addresses 192.168.1.10/24
nmcli con mod "WifiName" ipv4.gateway 192.168.1.1
nmcli con mod "WifiName" ipv4.dns "8.8.8.8"
nmcli con mod "WifiName" ipv4.method manual
Applying the Changes:
After setting the static IP, you need to restart the network connection to apply these changes:
nmcli con down "WifiName"
nmcli con up "WifiName"
Reverting to DHCP (Dynamic IP):
If you encounter any issues or decide to return to using DHCP, you can reset the configuration as follows:
nmcli con mod "WifiName" ipv4.method auto
nmcli con down "WifiName"
nmcli con up "WifiName"
