What are WiFiNpc.dat Error Messages?


Dynamic Link Library WiFiNpc.dat Errors

WiFiNpc.dat is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like WiFiNpc.dat, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Baidu WiFi Hotspot) could share the same WiFiNpc.dat file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DAT file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when WiFiNpc.dat is attempted to be loaded either when Baidu WiFi Hotspot is starting up, or in some cases already running. Some of the most common WiFiNpc.dat errors include:

Your WiFiNpc.dat file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Baidu WiFi Hotspot), or deleted by a malware infection. Furthermore, WiFiNpc.dat file corruption could be caused from a power outage when loading Baidu WiFi Hotspot, system crash while loading WiFiNpc.dat, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix WiFiNpc.dat Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your WiFiNpc.dat issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the WiFiNpc.dat error, please proceed to the Step 2 below.

Step 2: If recently installed Baidu WiFi Hotspot (or related software), uninstall then try reinstalling Baidu WiFi Hotspot software.

You can uninstall Baidu WiFi Hotspot software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".
  3. In the search results, find and click "Add or Remove Programs"
  4. Find the entry for Baidu WiFi Hotspot 5.1.4.124910 and click "Uninstall"

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many WiFiNpc.dat error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the WiFiNpc.dat error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your WiFiNpc.dat File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate WiFiNpc.dat file version. We maintain a comprehensive database of 100% malware-free WiFiNpc.dat files for every applicable version of Baidu WiFi Hotspot.

    Windows 10: C:\Program Files (x86)\Baidu WiFiHotspot\
  4. Restart your computer.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve WiFiNpc.dat problems.

If you are not currently backing up your data, you need to do so immediately.



Download WiFiNpc.dat Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying WiFiNpc.dat to your appropriate Windows system directory. Baidu typically does not release Baidu WiFi Hotspot DAT files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing WiFiNpc.dat and all other DAT files for Baidu WiFi Hotspot. An incorrectly installed DAT file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
