The editor of Downcodes brings you the solution to the network adapter error code 39. When your Windows system prompts network adapter error code 39, it usually means that the system cannot load the hardware device driver, which may be caused by the driver being damaged, missing, or out of date. This article will provide several solutions to help you quickly fix this problem and restore network connectivity.
Network adapter error code 39 usually refers to Windows being unable to load the driver for the hardware device, possibly because the driver is corrupted or missing. To resolve this issue, you can try the following: update the driver, uninstall and reinstall the network adapter driver, or use system restore. Among them, updating the driver is the most direct and common solution, because many times error code 39 is caused by the driver version being out of date or incompatible with the current system.
Updating drivers can be done directly through Device Manager. First, use the control panel or right-click "This PC" and select "Manage", enter the device manager, find the network adapter in question, right-click and select "Update Driver". You can then choose to automatically search for updated drivers and let the system find and install them on its own, or if you have already downloaded the latest drivers, you can choose to install them manually from your computer. This step can resolve incompatibility issues caused by older drivers.
Updating drivers is the first step in solving many hardware problems, especially when you encounter a situation like error code 39. First, automatic driver updates allow Windows to try to find and install the latest drivers that are best for your device. If the automatic update cannot solve the problem, you can visit the network adapter manufacturer's official website and manually download and install the latest driver. Different manufacturers will provide detailed installation guides to ensure that users can complete the installation process correctly.
When updating the driver, it is recommended to back up the current driver version. This is because new drivers can sometimes introduce new problems. If a newly installed driver causes your device to not work properly, you can easily roll back to the previous version.
If a simple update doesn't work, the next step is to try uninstalling the network adapter driver and then reinstalling it. Find the network adapter in the device manager, right-click and select "Uninstall Device", and confirm the operation in the pop-up dialog box. After the uninstallation is complete, restart your computer. Windows will try to reinstall the driver on startup.
Sometimes, after uninstalling a driver, it is more efficient to manually install the latest version than to install it automatically. This is because Windows may choose to install a driver that is more stable but not the latest version, whereas manual installation ensures you get the latest features and fixes.
If none of the above methods solve the problem, you may consider using system restore. System Restore can return the computer to an earlier recovery point, that is, a state where Network Adapter Error Code 39 was not encountered. Search for "Create Restore Point" in the Start menu, enter the System Protection tab of System Properties, and click "System Restore". In System Restore, select an appropriate restore point and follow the prompts to complete the restore process.
System Restore is a more thorough solution because it undoes installed programs and system changes, not just drivers. Therefore, please make sure you have backed up all important files before using it.
Error code 39 may sometimes be caused by improper modification or damage to related configuration items in the registry. Fixing this problem may require editing the registry, which is a higher-risk operation and it is recommended to make a complete system backup before proceeding.
First, open the Registry Editor (enter the "regedit" command in the run window), and then navigate to the key HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass. In this location, you need to find the key related to the network adapter. Under the relevant key, if there are items named "UpperFilters" and "LowerFilters", delete these two items and then restart the computer.
You must be very careful when editing the registry, as incorrect changes may cause the system to not start properly.
Through the above methods, most situations encountered with network adapter error code 39 can be solved. It is always recommended to try the least invasive solutions first, such as updating or reinstalling drivers, and then work your way up to more complex solutions.
