Using the GUI

1. Open settings and navigate to Wi-Fi.

2. Locate your connection and click the gear icon.

3. Select the IPv4 tab and set IPv4 Method to Manual.

4. Populate the Address, Netmask, Gateway, and DNS fields with the following values:

   • Address: 192.168.x.x - It's often easiest to find the current dynamic IP address and simply make that one static. Run $ hostname -I. Otherwise, you can select one from the IP range: Find Router IP Range
   • Netmask: 255.255.255.0
   • Gateway: 192.168.x.x - Find this IP by running $ route -n
   • DNS: 208.67.222.222, 208.67.220.220 - OpenDNS Nameservers

5. You're Done!

Using the Command Line

1. sudo apt install network-manager

2. nmcli -d to identify network interface -> wlp1s0

3. Open netplan config file, sudo vim /etc/netplan/50-cloud-init.yaml, and make sure it says the following:

   network:
       wifis:
           wlp1s0:
               optional: true
               access-points:
                   "<SSID>":
                       password: "<password>"
               dhcp4: false
               addresses:
                   - <static-ip-of-your-choice>/24
               routes:
                   - to: default
                   via: <router-private-ip>
               nameservers:
                   addresses: [208.67.222.222, 208.67.220.220]

4. sudo netplan apply. This command may log you out. To log back in, ssh username@static-ip-you-chose.

5. Done!
