Why do some Windows 11 PCs connect to Wi‑Fi only after sign-in?

There are group policy and power-management settings that can affect whether networking initializes before sign-in. Review wireless adapter power-saving options, make sure the NIC is allowed to stay active, and check policies related to waiting for the network at computer startup. Updating or reinstalling the Wi‑Fi driver may also help.

Check your wireless authentication method first. With WPA2/WPA3-Enterprise and 802.1X configured for user authentication, the device may associate with the access point but not receive usable network access until someone signs in. Check whether the system gets a DHCP lease before logon. Also verify that the Wi‑Fi password or machine credentials are saved for pre-logon use.

Also clarify whether only the Internet indicator is delayed or whether the computer has no LAN connectivity. Windows may show no Internet when its connectivity check is blocked by a proxy or firewall, even though the network is already available. On Ethernet, give the switch link a little time to negotiate before assuming the connection is being delayed until login.

This isn’t universal to Windows 11, so compare the affected models and configurations with machines that work normally. On some laptops, especially certain models, BIOS security settings or a faulty driver can prevent the Wi‑Fi device from loading before login. If the adapter doesn’t appear in the pre-login environment at all, check BIOS updates and security or driver-signing settings.
