Issue: How to Fix Slow Wi-Fi after Windows 10 Creators Update?

I’ve just installed Windows 10 Creators Update and can’t connect to Wi-Fi for some reason. The adapter is working fine, but the connection is not established. Is it a Creators Update bug or a simple misconfiguration that I can fix manually? Please help asap.

Solved Answer

Windows 10 Creators Update is the newest version of Windows operating system, which has been rolled out in 11th of April, 2017. The upgrade reaches its users in phases to prevent the installation errors and overloaded update services. While the vast majority of Windows 10 users have already received the Creators Update installation pop-up and installed the update, the others are still eagerly awaiting for the new features to come. You must have already heard about Microsoft’s attempts to set people’s creativity free with the help of Creators Update’s improvements and new features, so we won’t expand on this topic here. Three weeks after the initial rollout of the upgrade, it turns out that the update has a bunch of drawbacks and bugs. If some of Windows 10 users can’t install the upgrade at all, the others lost the Wi-Fi connection or its speed. In this short post, we would like to address the slow Wi-Fi speed or no Wi-Fi at all bug because it appears one of the most common and most frustrating.

Tips on how to fix slow Wi-Fi connection or no Wi-Fi connection after Creators Update

If you can’t get onto the Internet after the installation of the Creators Update, check wireless network adapter. If it’s turned on, we would highly recommend you to power cycle the modem and the wireless router. If that did not help, try to renew your IP address using Command Prompt:

• Right-click Windows key and select Command Prompt (Admin).
• Type the following commands and press Enter after each of them:
  Type netsh winsock reset
  Type netsh int ip reset
  Type ipconfig /release
  Type ipconfig /renew
  Type ipconfig /flushdns
• Then close everything and try to connect to the Internet.

Update network adapter driver

The Creators Update might have damaged the network adapter driver or the upgrade may be incompatible with the current version of the aforementioned driver. Therefore, the slow Wi-Fi connection speed may be related to the outdated network adapter driver. To update it, you should:

• Right-click on Windows key and select Device Manager.
• Select Network adapters and select your network adapter.
• Click it and select Update driver software.
• If needed, reboot your PC.

Disable Windows Auto-Tuning if it is active

• Right-click on Windows key and select Command Prompt (Admin).
• Type netsh int tcp set global autotuninglevel=disabled command and press Enter.
• If the command was successfully executed, you will receive a confirmation OK.
• Close CMD and reboot your PC.

If none of the above-mentioned steps helped, you should then try to run the Network Troubleshooter. For this purpose, type Network Troubleshooter in Cortana and launch the tool. It may fix the issue automatically or at least narrow it.

Last, but not least, we would strongly recommend you to disable your anti-virus and Windows Firewall, run the PC optimization tool, let say FortectMac Washing Machine X9, fix issues if it finds any, and then re-try to set the Wi-Fi connection again. No Wi-Fi? Still slow Wi-Fi? Then you should either wait for Microsoft to fix this Creators Update bug automatically or roll back to the Anniversary Update.
