Still, we recommend using a third-party antivirus instead of relying on Windows Defender because it doesn’t have the same level of protection as other antivirus programs. ESET NOD32 is a good place to start.

Its main advantage is its strong detection rate and real-time protection against all types of malware threats.

⇒ Get ESET NOD32

5. Re-register the Wlanapi.dll file

Re-registering a DLL file is usually done when something has changed in the system that prevents it from loading properly or accessing certain resources. The most common reason for this is due to a corrupted registry entry.

For example, if you have recently installed new hardware or updated drivers, there may be issues with your system configuration that prevent the DLL from loading correctly.

Although a handful of users reported this to be the best solution for the Wlanapi.dll missing error, it’s worth noting that re-registering DLL files does not always work.

So, if it doesn’t help your problem, you might need to look for other solutions. That’s all we had for this article but do check out our guide on how to deal with a similar error when the akisp11.dll error occurs.
