The ERROR_ADAP_HDW_ERR system error, with code 57 (0x39), appears when Windows can’t communicate with the network adapter. The error message reads, A network adapter hardware error occurred.
Common causes for the error include driver issues, misconfigured network settings, conflicts triggered by third-party apps, loose connections, and hardware malfunction.
Before you start troubleshooting, install all pending Windows updates, inspect the adapter for damage, reconnect the network adapter (if using an external one), and make sure the connections are in order. For 2 out of 5 users, these basic checks should fix ERROR_ADAP_HDW_ERR.
How do I fix ERROR_ADAP_HDW_ERR?
1. Update the network adapter’s driver
- Press Windows + X to open the Power User menu, and select Device Manager.
- Expand the Network adapters entry, right-click on the active adapter, and select Update driver.
- Click on Search automatically for drivers and wait for Windows to install the best locally available version.
- Reboot the PC to apply the changes.
If Windows can’t find a better version while updating the network driver, I recommend you search the manufacturer’s website, locate the latest release, and then manually install the driver.
2. Uninstall conflicting applications
- Press Windows + R to open Run, type appwiz.cpl in the text field, and hit Enter.
- Select any app downloaded or updated around the same time the issue first appeared, and click on Uninstall.
- Follow the on-screen instructions to complete the process.
- Restart the computer and check for improvements.
Often, a quick app removal doesn’t fix ERROR_ADAP_HDW_ERR due to the files and cache left behind post-installation. In this case, it’s best to use a top-rated software uninstaller which will clear all leftover files and Registry entries.
