I use Linux for my firewall etc. Normally when it works fine it gets to the login and then after a few seconds just continues. Then it allows me to get my broadband etc to work on my computer. Currently it just sits on the login screen and thats it. I can therefor not connect to the internet.

It seems your Linux firewall system is not proceeding beyond the login screen as it normally does, preventing you from accessing the internet. This could be due to several reasons, such as a recent update that didn't complete correctly, a configuration issue, or a service failing to start. To troubleshoot:

Check System Logs: After logging in, check the system logs for errors or warnings. To view system logs, you can use commands like journalctl -xe or dmesg.

Review Startup Services: Ensure that all necessary services, especially those related to networking and firewall, are set to start on boot. Use commands like systemctl status service name to check the status of specific services.

Network Configuration: Verify your network configuration. Ensure that your network interfaces are correctly configured and your firewall is not blocking your connection.

Safe Mode/Recovery: If the issue persists, try booting into safe or recovery mode. This might bypass the problematic component, allowing you to investigate further or revert recent changes.

Seek Specific Logs for Firewall/Networking: Since the issue affects internet connectivity, focus on logs and configurations related to networking and firewall services.
