The internet is part of our lives and, therefore, indispensable. A stable connection is necessary. However, some users report that Bitdefender crashes Starlink Internet. Users using both Starlink for internet access and Bitdefender for security could not help but feel frustrated with sudden connection drop-offs, slow speeds, or internet failure.

Why Does Bitdefender Crash Starlink Internet?
The few reasons Bitdefender is interrupting the Starlink internet are as follows:

The strong firewall on Bitdefender occasionally mistakes the Starlink network for some potential threat, therefore blocking all the connections, hence interrupting internet services.

Web Protection in Bitdefender scans and filters traffic across the internet, and if its function causes a conflict with the Starlink network in a way, the speeds of this internet sometimes lose their connections.
3. DNS Filtering Issues
It changes your DNS settings, which is good for security purposes. But in the case of Starlink, it requires fixed DNS configurations and might conflict, causing disconnections in your internet.
4. VPN and Network Settings
There is a built-in VPN in Bitdefender, and these network security elements may interfere with the dynamic system of Starlink’s IP.
