WiFi keeps dropping on Windows 11 22H2 — the real fix

When this hits

You're sitting at your desk, connected to your home or office WiFi. Everything's fine for 10-20 minutes. Then — boom. The WiFi icon in the taskbar shows a globe with a red X, or it switches to the little antenna with no bars. Your browser says "No internet". Wait a few seconds, it reconnects. Then it happens again. This is not your router dying. It's Windows being too clever for its own good.

Root cause

Windows 11 22H2 introduced a default power saving profile for Wi-Fi adapters. When the system thinks the adapter is idle (even for a few seconds), it puts it into a low-power state. The driver then takes too long to wake up, and the connection drops. Microsoft's logic: save battery on laptops. The problem is this setting is enabled on desktops too — or on laptops plugged into power. You don't need it, and it causes exactly this behavior.

I've fixed this on Dell XPS 13, Lenovo ThinkPad X1 Carbon, and HP EliteBooks running Windows 11 22H2. Same fix every time. Not a driver issue, not a router issue — it's the power management setting.

Fix it in 2 minutes

1. Right-click the Start button and select Device Manager.
2. Expand Network adapters. You'll see something like "Intel(R) Wi-Fi 6 AX201 160MHz" or "Realtek RTL8822BE Wireless LAN".
3. Right-click your Wi-Fi adapter and choose Properties.
4. Go to the Power Management tab.
5. Uncheck the box that says "Allow the computer to turn off this device to save power".
6. Click OK and close Device Manager.
7. Reboot your machine.

That's it. No registry edits, no command-line magic. Just one checkbox.

If it still drops after this

Sometimes the power saving setting is locked by the manufacturer's own software. Here's what else to check:

1. Check your power plan

Open Control Panel > Power Options. Make sure you're on High performance or Balanced. Click Change plan settings > Change advanced power settings. Scroll to Wireless Adapter Settings > Power Saving Mode. Set it to Maximum Performance.

2. Update your Wi-Fi driver

Go back to Device Manager, right-click the adapter, choose Update driver > Search automatically for drivers. If Windows finds nothing, go to your laptop or motherboard manufacturer's support site and grab the latest driver directly. Intel has a driver update tool that often finds newer versions than Windows Update.

3. Disable 802.11n mode (rarely needed, but worth a try)

In Device Manager, open the adapter's Properties > Advanced tab. Look for 802.11n mode or Wireless Mode. Set it to 802.11a/b/g or 802.11ac — not 802.11n if your router is old. This is a long shot but it's fixed some stubborn cases.

4. Check for interference

Run netsh wlan show wlanreport in an admin command prompt. It generates an HTML report in C:\ProgramData\Microsoft\Windows\WlanReport. Open it and look for repeated disconnects with reason "Peer disassociated" — that's the power saving fix not sticking. If you see "Nic disassociated" with no reason, your driver's toast. Update it.

5. Last resort: reset TCP/IP stack

Open Command Prompt as admin and run:

netsh int ip reset
netsh winsock reset
ipconfig /flushdns

Then restart. This rarely fixes WiFi drops, but it's harmless and some people swear by it.

Quick note: If you're on a corporate laptop with locked-down Group Policy, the power management checkbox might be grayed out. In that case, talk to your IT admin. There's a registry workaround but it's not worth the headache on a managed machine.

I've seen this exact issue on probably 60+ machines since Windows 11 22H2 dropped. The power saving checkbox fix has worked ~90% of the time. The other 10% needed a driver update. Don't waste time replacing hardware or resetting Windows — try this first.
