Basic Network Troubleshooting

Basic Network Troubleshooting

When a network connection isn’t working, a few simple commands can help determine where the problem is.

Check your network interface

Start by checking whether BcalcOS sees your network hardware:

ip addr

Look for your network interface and an assigned IP address.

Test Internet connectivity

To check whether you can reach the Internet without relying on DNS, try:

ping -c 4 1.1.1.1

If you receive replies, your computer can reach the Internet.

Test DNS

Next, try reaching a website by name:

ping -c 4 bcalcos.org

If the first test works but this one fails, you may have a DNS problem rather than a general Internet connection problem.

If you still cannot connect

If these basic tests don’t identify the problem, restarting the network connection or rebooting the computer may resolve a temporary issue.

If the problem persists, consider posting the details in the Help & Support category. Include the commands you tried and their results.
