Microsoft recently released a fresh Cumulative update for users on the Windows 10 Anniversary Update.
The update serviced as KB3201845 pushed the OS to build 14393.479 and came up with a number of fixes and performance improvements.
However, after installing the update, few people have been reporting issues with their WiFi connection around the web and Microsoft too has confirmed of the issue in their community/forums about the same and promised a fix soon.
The problem is said to be arising from the misconfigured DHCP on Windows, as soon as you install the update. For a novice user, this could be very frustrating but thankfully at-least you can manually try to eliminate it with a few tricks.
Restarting your PC
Of course, the first thing you can try out is to restart Windows. Most of the times, this works. Restart your PC to see if that fixes your connection problem.
Running the Network Troubleshooter
- In the search box on the taskbar, type network troubleshooter, and then select Identify and repair network problems from the list of results.
- Follow the steps in the troubleshooter and see if that fixes the problem.
Running Networking Commands (command line)
At the command prompt, run the following commands in the listed order, and then check to see if that fixes your connection problem:
- Type netsh winsock reset and press Enter.
- Type netsh int ip reset and press Enter.
- Type ipconfig /release and press Enter.
- Type ipconfig /renew and press Enter.
- Type ipconfig /flushdns and press Enter.
Use network reset to reinstall network devices
This can help solve connection problems where you can connect to the Internet, but not to shared network drives. It removes any network adapters you have installed and the settings for them.
After your PC restarts, any network adapters are reinstalled, and the settings for them are set to the defaults.
- Select the Start button, then select Settings > Network & Internet > Status > Network reset.
- On the Network reset screen, select Reset now > Yes to confirm.
Wait for your PC to restart and see if that fixes the problem.
