Ubuntu Static IP No Internet Fix

If you are unable to access the internet after setting a static IP on Ubuntu, you can try the following methods to resolve the issue:

1. Check the network connection: Ensure that the network connection is working properly, and that there are no issues with the ethernet or Wi-Fi connection.
2. Check the IP address and gateway settings: make sure you haven’t entered incorrect IP address and gateway when setting up a static IP. You can use terminal commands such as ifconfig or ip addr to view the current IP address and gateway settings.
3. Check the DNS settings: If the static IP is set correctly but cannot access external websites, it may be a DNS issue. You can edit the /etc/resolv.conf file and add the correct DNS server address. For example, you can add a public DNS server address:
4. Replace the current nameserver with 8.8.8.8 and 8.8.4.4
5. Restarting the network service: You can try restarting the network service to apply the new IP settings. You can use the following command to restart the network service:
6. Restart the networking service using systemctl.
7. Check the firewall settings: If the firewall is enabled on the system, make sure to set the correct firewall rules to allow network connections. This can be done using the ufw command or other firewall management tools.
8. Check the network devices settings: If you are connected to a router or switch within a local area network, make sure that the configuration of these devices is correct. For example, verify if the router has the correct static IP address and gateway configured, and if the DHCP server is enabled.

If the above methods are not able to solve the problem, further investigation may be needed on the network equipment, router, and system logs to understand specific error messages, and try reconfiguring the network settings.
