How to Fix WiFi Not Connecting on Windows 11 Due to WPA3 Incompatibility: Driver Updates, Transition Mode Settings, and Adapter Upgrade Guide

WPA3 is the current WiFi security standard, and virtually every router sold since 2021 ships with it enabled by default or as the recommended setting. The problem: Windows 11’s WPA3-SAE (Simultaneous Authentication of Equals) implementation has broken with at least two major update cycles, and older Intel and Qualcomm adapters have their own firmware bugs that prevent a clean WPA3 handshake even on fully patched systems. The result is a PC that shows the network SSID but fails to connect, loops through authentication with no error, or displays the cryptic message “Some information has changed since the last time you connected.” Run a speed test once you restore connectivity to confirm your connection is performing at its expected speed.

Step 1 — Confirm WPA3 Is the Actual Problem

Before touching drivers or router settings, verify that WPA3 is specifically at fault rather than a generic WiFi issue:

1. Open your router’s admin interface and temporarily set the security mode to WPA2-Personal only (not mixed).
2. Try connecting from the affected Windows 11 device.
3. If the connection succeeds immediately on WPA2 but fails on WPA3, WPA3 compatibility is confirmed as the root cause. Proceed with the steps below.
4. If it still fails on WPA2, the issue is unrelated to WPA3 — check our home network speed audit guide for broader WiFi troubleshooting.

Step 2 — Install the February 2026 Cumulative Update (KB5077181)

Microsoft confirmed that the January 2026 optional update (KB5074105) introduced a regression that prevented some Windows 11 devices from connecting to WPA3-Personal networks. The fix shipped in Build 26200.7840 (KB5077181), released in February 2026. If your system has not installed this update — or if Windows Update has been paused — this is the first and most important step:

1. Open Settings → Windows Update and click Check for updates.
2. Look for the 2026-02 Cumulative Update for Windows 11 (KB5077181) and install it.
3. Restart when prompted, then attempt to reconnect to your WPA3 network.

If Windows Update is unavailable or the update does not appear, download KB5077181 directly from the Microsoft Update Catalog at catalog.update.microsoft.com. Select the version matching your architecture (x64 for most PCs, ARM64 for Snapdragon-based devices), run the .msu installer, and restart.

Step 3 — Update Your WiFi Adapter Driver From the Manufacturer

Windows Update delivers adapter drivers months behind the manufacturer’s release cycle. For WPA3-SAE, driver currency matters: early firmware revisions for common chipsets shipped with documented WPA3 handshake instability. Do not rely on Windows Update or your laptop manufacturer’s support page for driver updates — go directly to the chip manufacturer:

• Intel AX210 / AX211 / BE200: Download from Intel’s support site. Version 23.30.0 or later resolves the WPA3-SAE regression on these chipsets. Earlier versions have a confirmed race condition in the 4-way handshake that causes authentication failures under certain AP configurations.
• Qualcomm FastConnect 6900 / 7800: Download from the Qualcomm support portal or your OEM’s driver page labeled specifically as a “WLAN” driver, not a firmware bundle.
• MediaTek MT7922 / MT7925: Download from MediaTek’s support page or the OEM (common on ASUS and Acer laptops).

To identify your exact adapter: open Device Manager (Win + X → Device Manager), expand Network adapters, and note the exact model name. Right-click the adapter and choose Properties → Driver tab to see the current driver version before updating.

Step 4 — Enable WPA3 Transition Mode on Your Router

WPA3 Transition Mode (also called WPA2/WPA3-Personal mixed mode) allows the router to serve WPA3 to capable clients while accepting WPA2 connections from devices that cannot complete the SAE handshake. This is the most practical short-term workaround if you cannot immediately update Windows or adapter drivers:

• ASUS routers: Wireless → Security → Authentication Method → WPA2/WPA3-Personal.
• TP-Link routers: Wireless → Security → WPA2/WPA3-Personal (Mixed).
• Netgear routers: Advanced → Wireless Settings → Security Options → WPA2-PSK [AES] + WPA3-SAE.
• eero: eero uses WPA3 Transition Mode by default and cannot be configured to WPA3-only; most eero users are not affected by this issue.

Transition Mode does not reduce security for WPA3-capable devices — they still negotiate WPA3. Only the affected Windows 11 device falls back to WPA2 until its driver or OS is updated.

Step 5 — Check Protected Management Frames (PMF) Settings

WPA3 mandates Protected Management Frames (PMF / 802.11w) as a required feature, whereas WPA2 makes PMF optional. Some older adapters and drivers negotiate PMF incorrectly, causing authentication to fail even when the security mode appears compatible. If Transition Mode still does not resolve the connection:

1. In your router’s wireless security settings, set PMF to Optional rather than Required.
2. Attempt reconnection from the Windows 11 device.
3. Once drivers are updated, set PMF back to Required for full WPA3 compliance.

The error “Some information has changed since the last time you connected” in Windows 11 almost always indicates a PMF mismatch or a failure during Group Key Rotation after the initial handshake — driver updates fix both root causes definitively.

Step 6 — Forget and Re-Add the Network After Fixing Drivers

Windows caches WiFi network profiles including the negotiated security parameters. After updating drivers or changing router settings, the cached profile may conflict with the new configuration and prevent connection even after the underlying issue is resolved:

1. Open Settings → Network & internet → WiFi → Manage known networks.
2. Find your network name and click Forget.
3. Reconnect by selecting the network from the taskbar WiFi menu and entering your password.

When to Replace Your WiFi Adapter

If your adapter predates 2019, it may lack hardware support for WPA3-SAE entirely — driver updates cannot add capabilities the silicon does not support. Check your adapter’s specifications on the manufacturer’s site for WPA3 certification. For desktop PCs, a PCIe WiFi card with an Intel BE200 or AX210 chipset costs $25–$50 and adds full WPA3 support along with WiFi 6E or WiFi 7 capability. See our best WiFi PCIe cards guide for tested picks. For laptops, an M.2 module swap is possible on most models — our WiFi 7 laptop upgrade guide covers the process and compatible modules.

Quick Fix Summary

• Connects on WPA2 but not WPA3: Install KB5077181, update adapter driver from manufacturer.
• “Some information has changed” error: PMF mismatch — set PMF to Optional on the router; update driver.
• Network visible but authentication loops: Forget the network profile and reconnect after driver update.
• All fixes tried, still failing: Check if adapter hardware supports WPA3; consider PCIe or M.2 upgrade.
• Whole household affected: Enable WPA3 Transition Mode on router as a temporary workaround.
