Issue: How to fix “WiFi doesn’t have a valid IP configuration” error on Windows?

Hello. I purchased a Windows 10 laptop, which worked fine for quite a long time. However, for the last few weeks after installing a couple of updates, the system started encountering some problems related to Wifi connection. When trying to connect to the Internet, I get the “No Network Access” error with a yellow exclamation mark. I tried running an in-built troubleshooter, which notified: “Wifi doesn't have a valid IP configuration.” Ok, for some this message may seem useful, but I know nothing about IP configuration, so I would highly appreciate your help.

Solved Answer

Internet connection errors like the particular “WiFi doesn’t have a valid IP configuration” are very common and, indeed, extremely annoying as they completely isolate the user from the cyberspace. Not expanding much on behalf of connection types and equipment, we’ll just simply remind you that there is a wired and Wi-Fi (wireless) Internet connection.

Despite being more convenient, the latter connection type encounters considerably more problems than the first one. Currently, many people are dealing with “No Network Access” error, which shows up out of nowhere and does not provide information that could help for troubleshooting the issue.

Consequently, most of the users run Windows Network Diagnostics Troubleshooter, which returns the following message: “WiFi doesn’t have a valid IP configuration.” The message may slightly vary according to the system’s features, but the fact about IP configuration remains.[1]

This “WiFi doesn’t have a valid IP configuration” errors can even appear on the screen as soon as the user logs in to the computer. Unfortunately, the problem mostly affects devices running Windows 10 operating system. This is probably due to various updates that had different issues.[2]
