WiFi keeps dropping on Windows 10/11 – the real fix

You're in the middle of a Zoom call or maybe just browsing Reddit, and the WiFi drops. Not the whole network—just your machine. The icon shows a globe or a yellow triangle. You reconnect, it works for five minutes, then drops again. Sound familiar? I've seen this on dozens of laptops running Windows 10 and 11, especially Dell XPS and Lenovo ThinkPads. The trigger is almost always the same: Windows decides your WiFi adapter is using too much power and turns it off to save battery. Even when you're plugged in.

Root cause – the hidden power saving checkbox

Windows has a setting buried in the Device Manager that lets your network adapter go to sleep when it thinks it's idle. The problem is, the adapter doesn't know the difference between "idle" and "waiting for the next packet." So it drops the connection, then wakes up, reconnects, and loops. The fix is to tell Windows to stop managing your adapter's power. Period.

Step-by-step fix

1. Open Device Manager – Right-click the Start button and select "Device Manager." Or press Win+X, then M.
2. Find your wireless adapter – Expand "Network adapters." Look for something like "Intel(R) Wi-Fi 6 AX201" or "Realtek RTL8822CE." Don't pick the Bluetooth one.
3. Open properties – Right-click your wireless adapter and choose "Properties."
4. Go to the Power Management tab – It's the third tab. You'll see a checkbox that says "Allow the computer to turn off this device to save power." It's checked by default.
5. Uncheck it – Click the box to remove the check. Then click OK.
6. Reboot – Restart your machine. This forces the adapter to reload with the new setting.

What if it still drops?

If the checkbox was already unchecked, or if the Power Management tab is missing entirely, you've got a different problem. Here's what to check next:

• Driver issues – Go back to Device Manager, right-click your adapter, select "Update driver," then "Browse my computer for drivers," then "Let me pick from a list." Try an older version of the driver. I've seen Intel's latest drivers cause exactly this issue on Windows 11 22H2.
• Router congestion – Download a free tool like WiFi Analyzer (from the Microsoft Store) and check if your channel is crowded. If you see 10 other networks on the same channel, change your router's channel to a less busy one.
• USB 3.0 interference – This one's weird but real. USB 3.0 ports emit radio noise at 2.4 GHz. If your laptop has a USB 3.0 device plugged in next to the WiFi antenna, it can kill your signal. Move the USB device to a different port or use a USB extension cable.
• Power plan settings – Open Control Panel > Hardware and Sound > Power Options. Click "Change plan settings" next to your active plan, then "Change advanced power settings." Find "Wireless Adapter Settings" and set "Power Saving Mode" to "Maximum Performance."

Had a client last month whose WiFi kept dying every 90 seconds on a brand new HP Pavilion. The Power Management checkbox was the culprit. Unchecked it, rebooted, and it's been solid for three weeks now. Nine times out of ten, that's the fix. Start there.
