How to fix Wi-Fi problems on the Windows 10 Fall Creators Update

The Windows 10 Fall Creators Update seems to have broken Wi-Fi connectivity for some users — Here are 4 ways to fix this problem.

Fixing Wi-Fi problems on the Windows 10 Creators Update

Although the Windows 10 Fall Creators Update improves many aspects of the OS, it appears that not everyone is having a smooth upgrade, as some users are experiencing a few problems after installing the new version.

During the initial rollout of the Fall Creators Update, a small number of users have been reporting bugs and features not working, including Wi-Fi connectivity problems. After installing version 1709, users have been complaining about very slow Wi-Fi speeds, and others have reported being unable to connect to a wireless network and losing their networking settings like previously configured DNS settings.

While this might just be a problem with the Windows 10 Fall Creators Update itself, sometimes there are other factors that can cause connectivity issues. During the upgrade process, the driver for the Wi-Fi adapter might have got corrupted. You probably don’t have installed the latest driver, which happened to work with the previous version, but it doesn’t work with the new release. There could be some configuration problems and a number of other things.

In this guide, you’ll learn a few ways to fix the Wi-Fi problems after installing the Windows 10 Fall Creators Update (1709).

If everything is working again, you’re all done. If it’s still not working, try the following method.

How to update a Wi-Fi adapter driver

In the case, you’re still experiencing slow Wi-Fi speeds, or problems connecting online, your computer may not be running the latest version of the driver.

You can resolve this issue by downloading and installing the latest driver from the network adapter manufacturer’s support website. 

Quick Tip: If there isn’t an update for the network adapter, check to see if there is a beta version of an upcoming release, as it may just work with the new version of Windows 10.

Typically, you want to use their instructions to install the latest version of the driver, but you can also use these steps:

  1. Download the latest available Wi-Fi adapter driver from your manufacturer’s website.

  2. Extract the drivers to an empty folder.

  3. Use the Windows key + X keyboard shortcut to open the “Power User” menu and select Device Manager.

  4. Expand Network adapters.

  5. Right-click your Wi-Fi adapter, and select Update Driver Software.

  7. Click Browse to locate the adapter driver.

  8. Check the Include subfolder option.

  9. Click Next to complete the task and install the new driver.

Sometimes, when nothing works, you can also try an even older version of the Wi-Fi adapter driver, such as those designed for Windows 8.1 or Windows 7, which may fix the problem temporarily until there is a permanent fix.

How to roll back to the previous version of Windows 10

If you’re still having connectivity issues, then chances are there may be a bug inside the new version of Windows 10 or with the network adapter, and you may need to wait until there is an update for the adapter or the OS.

As a last resort, you can go back to the previous version of Windows 10 until the Wi-Fi problem is resolved.

You can follow the instructions in the video below to rollback (or uninstall) the Windows 10 Fall Creators Update from your computer.

Wrapping things up

It’s also a good idea to check your connection settings on Control Panel > Network and Internet > Network Connections, and open the adapter’s properties. In the past, users had complained about the TCP/IPv4 getting disabled and DNS settings getting reset after the upgrade. In addition, you should always reboot your router, and restart any wireless extender on every method you try, just to see if it helps to resolve the Wi-Fi slow speed or connectivity problems as you follow the steps mentioned above.

Alternatively, you can also connect online using a wired connection using an Ethernet adapter. If your laptop doesn’t include a port to plug a network cable, you can get an adapter from Amazon.

Update November 16, 2017: If you’re losing Wi-Fi connectivity after installing the Fall Creators Update, you can also try this workaround, which seems to be working for some users.
