Answer
Check the network on another device, reconnect, restart the modem and router, run the Windows troubleshooter, then reset the adapter or network only if needed.
Check the starting state
Before changing Windows Wi-Fi, compare another device on the same network, record the SSID, signal, adapter state, IP status, VPN or proxy use, and the exact connection error. Keep the current state, exact message, and any recent change available so each result can be compared.
Choose the supported path
Separate a router or ISP outage, saved-network problem, weak signal, disabled adapter, driver issue, and authentication failure before using Network reset.
Isolate the problem
Test the same Wi-Fi on another device and test the PC on another network when possible.
Reconnect and restart
Turn Wi-Fi off and on, forget and rejoin the network, then restart the modem, router, and PC.
Run the troubleshooter
Use the Network and Internet troubleshooter in Get Help and apply only the changes it identifies.
Reset the adapter last
Update or reinstall the network driver from the PC maker. Use Network reset only after recording VPN and custom network settings.
Verify the result
the PC reconnects to the intended network after restart and reaches both the router and internet consistently. Repeat the original task once more after reopening the relevant app, connection, or Windows session so a temporary result is not mistaken for a fix.
Troubleshoot Windows Wi-Fi
If all devices are offline, only one SSID is missing, the adapter vanishes, credentials are organization-managed, or Network reset would remove needed VPN settings, stop broad resets and return to the last known state. Preserve the exact error, versions, device or account scope, and failed step before using the linked official support channel.
