Although the October 2018 Update (version 1809) improves many areas of Windows 10, no matter the version, users always seem to have problems during the upgrade process that affects Wi-Fi connectivity — for example, slow Wi-Fi speeds, unable to connect to a wireless network, missing configurations, or network adapter not working.
Usually, these problems can be traced to driver compatibility, bug, or configuration changes, which could be as a result of the new version, but sometimes there are other factors that can cause connectivity issues. During the upgrade process the driver for the Wi-Fi adapter may get 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.

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

Search for Device Manager, click the top result to open the experience.

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

Click the Browse option to locate the adapter driver.
Check the Include subfolder option.

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 tutorial below to uninstall the Windows 10 October 2018 Update from your device.
Wrapping things up
Also, it’s a good idea to check your adapter settings on Control Panel > Network and Internet > Network Connections, and opening the adapter’s properties. In the past, there have been reports about TCP settings getting disabled and DNS settings getting reset after an upgrade. Furthermore, you should always reboot your router 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.
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.
