wifi stopped working on my windows PC. can’t see any available networks, the wifi icon shows as disconnected, and when i ran the troubleshooter it mentioned the WLAN AutoConfig service.
tried restarting. didn’t fix it. the wifi adapter shows in device manager without any warning icons.
what is WLAN AutoConfig and why would it cause wifi to stop working? and what’s the fix when it’s the cause?
also: should i just turn it back on if it’s stopped, or is it stopping because something else is wrong that i need to fix first?
Starting WLAN AutoConfig from services.msc being the immediate fix for sudden WiFi loss is something more people should know. The service can get stopped by third-party software, Windows updates, or system events. Opening services, finding it, and clicking Start takes thirty seconds and brings WiFi back immediately if that’s the cause.
the startup type being set to automatic is the part that prevents recurrence. if the service is stopped and you just start it without changing the startup type to automatic, it won’t start automatically next reboot and you’ll have the same problem again. fix both the current state and the startup setting.
The dependency chain being worth checking is valid for persistent cases. WLAN AutoConfig failing to start can be caused by a dependency service not running correctly. The Dependencies tab in the service properties shows exactly what WLAN AutoConfig needs. Working down the chain to find the root stopped service is the diagnostic path.
WLAN AutoConfig is the windows service that manages wifi connections. it handles scanning for networks, connecting, and maintaining the connection. when it’s stopped or broken, wifi stops working entirely.
step 1: start or restart the service. press Windows+R > services.msc > find “WLAN AutoConfig” > right-click > start (if stopped) or restart (if running). set startup type to “Automatic” so it starts with windows.
if the service starts but wifi still doesn’t work: the service may be conflicting with something.
check dependencies: in the WLAN AutoConfig service properties > Dependencies tab. the services it depends on (remote procedure call, etc.) need to be running. verify they are.
reset network settings via command prompt (run as administrator):
netsh winsock reset
netsh int ip reset
ipconfig /flushdns
then restart.
reinstall the wifi adapter driver: device manager > network adapters > right-click wifi adapter > uninstall device > check “delete the driver software” > restart. windows will reinstall the driver on next boot.
if WLAN AutoConfig stops again after you start it: something is stopping it. check event viewer (search > event viewer) > windows logs > system > look for errors related to WLAN AutoConfig around the time it stopped. this usually points to a driver conflict or a corrupted service dependency.
The network troubleshooter catching service-level issues automatically is more capable than its reputation suggests. It checks service states, resets network components, and can fix WLAN AutoConfig issues without needing to know which service is the problem. Worth running before manually digging through services.msc.
