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.
Windows 10 includes a troubleshooting tool in the Settings app to find and fix a number of wireless and other network adapters problems automatically.
To use the Network Adapter troubleshooter, use the following steps:
Click on Update & security.
Click on Troubleshoot.
Select Network Adapter, and click Run the troubleshooter.
Select the network adapter you want to fix, in this case Wi-Fi.
Click Next to begin the process.
The troubleshooter will find and try to fix the Wi-Fi problem on your device. After the process completes, open your web browser and try to connect online. If everything is working again, you’re all done. If it’s still not working, try the following method.
Windows 10 also includes a handy tool that removes and then reinstalls all your network adapters, and resets all the networking components to its default settings, which can help to fix slow speeds or problems trying to connect online.
To reset your Wi-Fi adapter, do the following:
Click on Network & Internet.
Click the Network reset link.
Click the Reset now button.
Click Yes to confirm.
Click Close and restart your computer.
Using this method, you may need to reinstall other networking software, such as VPN client or virtual switch software. In addition, you’ll need to manually reconnect to any Wi-Fi network, which may require to enter a password.
You can watch the video tutorial below to see in more details the steps to fix a wireless adapter on Windows 10.
If everything is working again, you’re all done. If it’s still not working, try the following method.
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.
Typically, you want to use their instructions to install the latest version of the driver, but you can also use these steps:
Download the latest available Wi-Fi adapter driver from your manufacturer website.
Extract the drivers to an empty folder.
Use the Windows key + X keyboard shortcut to open the “Power User” menu and select Device Manager.
Expand Network adapters.
Right-click your Wi-Fi adapter, and select Update Driver Software.
Click Browse my computer for driver software.
Click Browse to locate the adapter driver.
Check the Include subfolder option.
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.
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.
It’s also a good idea to check your connection settings on Control Panel > Network and Internet > Network Connections, and opening 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 you’re laptop doesn’t include a port to plug a network cable, you can get an adapter from Amazon.
Installing the new version of Windows 10 should be an easy process, but if you experience any errors, bugs, or any other issue that you can’t figure out, you can submit your questions in the PUREinfoTech forums to get help.
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.
