How to fix
Network Adapter crashing
on Windows

Hello. My Internet connection keeps disconnecting because the network adapter stops working. What can I do to fix this?

When a network adapter crashes in Windows, users can have a frustrating experience. Driver[ref en-1]] issues are a common source of this problem. Drivers that are outdated or incompatible with the adapter can cause it to malfunction, resulting in slow internet speeds, disconnections, or the inability to connect to the internet at all. Hardware issues, such as a faulty adapter or network card, can also cause the problem in some cases.

Conflicts with other installed applications can also cause a network adapter to crash. Third-party network applications, such as firewalls, VPNs, or antivirus software, can occasionally interfere with network adapter functionality. Furthermore, outdated software can cause compatibility issues and crashes.

The consequences for users can be severe. Slow internet speeds can have an impact on work productivity and impede online activities like streaming and gaming. Frequent disconnections can also be annoying and disrupt ongoing tasks like downloading or uploading files. In extreme cases, being unable to connect to the internet at all can have serious consequences, such as missed deadlines or revenue loss.

Fortunately, there are several options for dealing with a network adapter crash. Updating drivers and software, as well as disabling conflicting applications and resetting network settings, can frequently resolve the issue. This guide will walk you through 5 steps that should help you fix Network Adapter crashing in Windows.
