The Intel Wi-Fi 6 AX201 is a wireless network adapter commonly found in Windows laptops and compatible desktop computers. It allows users to connect to Wi-Fi networks and access the internet without relying on a wired connection.
However, some users encounter an unexpected problem where the Intel AX201 stops working and displays Error Code 43 in Device Manager. When this happens, the Wi-Fi option may disappear from Windows, wireless connections may fail, or the adapter may show a yellow warning icon. This guide explains how to troubleshoot Intel AX201 Code 43 on Windows 10 and Windows 11.
Solution 1: Restart Windows and Perform a Power Reset

Frequently Asked Questions
Can restarting my router fix Intel AX201 Code 43?
A router restart may help if Wi-Fi connects but internet access fails. Code 43 points to a problem Windows detected with the adapter itself, so check Device Manager before changing router settings.
What should I do if Code 43 appeared right after a driver update?
In Device Manager, open the Intel AX201's Properties → Driver tab and select Roll Back Driver if available. If the option is unavailable, check your PC manufacturer's support page for a previously working driver for your exact model.
Does persistent Code 43 mean the Wi-Fi adapter needs to be replaced?
No. The code alone cannot distinguish a hardware fault from a driver or firmware problem. If it persists after a supported power reset and driver reinstall, run your PC manufacturer's hardware diagnostics or contact support before buying a replacement.
If Code 43 continues after software troubleshooting, hardware diagnostics or professional support may be necessary to restore wireless connectivity.
