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.
