WiFi keeps disconnecting on Windows 11 22H2 — real fix

Quick answer: Open Device Manager, find your WiFi adapter under Network adapters, right-click it > Properties > Power Management tab, uncheck "Allow the computer to turn off this device to save power."

This is the single most common cause of random WiFi disconnects on Windows 11 22H2. What's actually happening here is that Windows' power management driver decides your adapter isn't being used enough and puts it into a low-power state. The problem? The threshold is way too aggressive — it'll kill the connection even when you're actively streaming or browsing. I've seen this on Dell XPS 13s, Lenovo ThinkPads, and HP Spectres especially. The fix takes 10 seconds and it's permanent.

Why this happens

Windows 11 22H2 introduced a more aggressive default power policy for network adapters. Microsoft's logic was battery life. The reality is it breaks WiFi for a lot of people. The adapter enters D3 (device sleep) state momentarily, your router sees the connection drop, and you have to reconnect. It's not a driver bug — it's a policy bug.

The fix steps

Open Device Manager — press Win+X and select Device Manager, or run devmgmt.msc from the Run dialog (Win+R).
Expand "Network adapters" — find your WiFi adapter. It'll usually say something like "Intel(R) Wi-Fi 6E AX211" or "Realtek RTL8822CE". Don't touch Bluetooth adapters or Ethernet.
Right-click your WiFi adapter and select Properties.
Go to the Power Management tab — if you don't see this tab, your adapter doesn't support the feature. Skip to the alternative fix below.
Uncheck "Allow the computer to turn off this device to save power" — click OK.

That's it. Your WiFi won't randomly drop anymore. The reason step 5 works is simple: Windows can no longer force your adapter to sleep. The adapter stays active even when idle, so your connection remains stable.

What if the Power Management tab is missing?

Some adapters, especially newer Intel and Realtek ones, hide this tab. Here's what to do:

Open Command Prompt as Administrator — press Win+X, select Terminal (Admin).
Run this command to see your adapter's index number:
```
powercfg /devicequery wake_armed
```
Look for your WiFi adapter's name in the list. Note its device instance path (the long string next to it).
Now disable power saving for that adapter:
```
powercfg /setdcvalueindex SCHEME_CURRENT SUB_NONE 00000000-0000-0000-0000-000000000000 0
```
Replace the GUID with your adapter's actual GUID from step 2. Or, simpler: use this command to disable all network adapter power saving:
```
powercfg /change standby-timeout-ac 0
```
This disables the system standby timer, but you'll need to adjust it back if you want sleep later.

A less invasive approach: update your WiFi driver manually. Go to your laptop manufacturer's support site (Dell, Lenovo, HP, etc.) and download the latest WiFi driver for your exact model. Don't use Windows Update — it often pushes generic drivers that don't fix this. Realtek and Intel both released specific driver updates in 2023 that address the power saving issue.

Alternative fix: Registry edit

If the UI method doesn't stick (some laptops reset this setting on reboot), you can force it via the registry:

Open Registry Editor (regedit).
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}.
You'll see subkeys named 0000, 0001, etc. Click each one and look for a key called DriverDesc that matches your WiFi adapter name.
Once you find it, create a new DWORD (32-bit) value named PnPCapabilities and set it to 24 hexadecimal. This tells Windows not to power-manage this device.
Reboot.

This is more permanent because Windows won't override registry settings on driver updates. The value 0x24 means "don't allow power management" in the PnP subsystem.

Prevention tip

Once you've applied this, Windows Update might still push a driver that resets the setting. To prevent that: go to Windows Update > Advanced options > Pause updates for 7 days, then manually download and install driver updates from your laptop manufacturer instead. I've seen the December 2023 cumulative update re-enable the power saving on some systems. If it happens again, just re-apply step 5. Takes ten seconds.

One more thing: if you use a USB WiFi adapter, this same fix applies. Go to Device Manager, find your USB adapter under Network adapters, and disable power saving there too. USB selective suspend in Windows 11 can also cause drops — you can disable that in Power Options > Change plan settings > Change advanced power settings > USB settings > USB selective suspend setting > set to Disabled. But start with the adapter power management fix first. It fixes 90% of cases.
