How to fix
Wi-Fi disconnects after sleep mode
on Windows

Hello, I have been having a rather strange problem recently, my laptop disconnects from Wi-Fi every time it wakes up from sleep. This started happening as soon as automatic Windows updates were applied last week, so I'm not quite sure - maybe it is related to that. I need to restart my laptop every time to make the Wi-Fi work once again, which is really annoying.

Windows might sometimes not work as expected for no apparent reason, and users that come across such issues have the right to be annoyed. In reality, every malfunction in the operating system has a reason, although the causes for this can differ greatly.

Wi-Fi disconnecting after sleep mode in Windows is not a new phenomenon and has been bugging users for many years now - there is no ultimate solution for the problem to this day. However, there are plenty of troubleshooting steps that can help users to find the root cause of the problem and do something about it.

Most commonly, users describe a problem as a persistent one. After they leave their PCs for a while, their devices access the sleep mode to save electricity consumption. Under normal circumstances, all the Windows work should be resumed as normal as soon as they touch any key on the keyboard or click a mouse.

For some people, this results in Wi-Fi disappearing, and unless they restart their computers, no internet is available. Without a doubt, this shouldn't be the case.

One of the most common reasons for Wi-Fi disconnecting after sleep mode is the network adapter drivers.[ref en-1] Sometimes, they might get corrupted or outdated, which may result in the internet connection malfunctioning. Therefore, updating drivers might help users fix the problem.

For some people, issues started after applying the latest Windows update. It is not unusual for updates to cause certain malfunctions on the device, so uninstalling them can help resolve the situation. In addition to these solutions, we provide additional ones below, so please try them one by one to see which one is helpful to you.

Before proceeding, we suggest you attempt to fix underlying Windows issues with the help of a powerful PC repair tool [d1], which can quickly and easily find damaged system files and replace them with brand new ones, resolving errors, crashes, BSODs,[ref en-2] registry issues, and other common Windows problems automatically.

Network adapter drivers may be the main cause of Wi-Fi disconnecting after sleep mode. Thus, we recommend updating your network adapters.

Fix 4. Uninstall the latest update [workaround]

If your problems started after Windows updated (be it automatically or whether you initiated the process yourself), you can reverse it by uninstalling the latest Windows update. Make sure you pause the update process once done so that it wouldn't be applied once again.

To pause the updating process, follow these steps:

• Click Pause updates for 7 days (in Windows 11, this option is under More options).
