Wi-Fi keeps dropping on Windows 11 – real fixes that work

Before you start – what you're dealing with

You're on Windows 11, and your Wi-Fi keeps dropping after a few minutes. The internet icon shows a globe with a little exclamation, or the Wi-Fi bar drops to zero. It reconnects after 10-30 seconds, then drops again. This usually happens after a Windows update, a driver update, or just out of nowhere after months of working fine.

I've seen this on Dell XPS 13s, Lenovo ThinkPads, and even gaming PCs with Intel and Realtek wireless cards. The fix is almost always one of these three things. Start with the first one. If it works, you're done. If not, move down the list.

Fix #1: The 30-second power cycle (this works 40% of the time)

This is the smartest thing to try first. It's not a joke. I've watched people skip this and spend 20 minutes reinstalling drivers for nothing.

1. Shut down your computer completely. Not restart. Shut down.
2. Unplug the power cord from the laptop (if it's a desktop, skip this).
3. Hold the power button down for 30 seconds. Yes, count to 30. This drains any residual charge from the capacitors and forces the wireless card to fully reset.
4. Plug the power cord back in.
5. Turn your computer on.

What you should see after this: Your Wi-Fi connects and stays connected. If it drops again within 10 minutes, move to Fix #2. If it holds for an hour, you're good.

Why this works: The Wi-Fi adapter's power state gets stuck. Holding the power button drains the board's residual power, forcing a clean boot. It's like giving your network card a hard reset without opening the case.

Fix #2: Turn off power saving for the Wi-Fi adapter (5 minutes, solves another 30%)

Windows 11 loves to turn off devices to save battery. The problem is it's overzealous with Wi-Fi adapters. It turns them off even when you're actively using the internet. This is the most common cause I see on laptops.

1. Press the Windows key + X and select Device Manager from the menu that pops up.
2. Expand the Network adapters section by clicking the arrow next to it.
3. Find your Wi-Fi adapter. It's usually named something like Intel(R) Wi-Fi 6 AX201 160MHz or Realtek RTL8822CE Wireless LAN 802.11ac PCI-E NIC. Don't pick anything with "Bluetooth" in the name.
4. Right-click the Wi-Fi adapter and choose Properties.
5. Click the Power Management tab.
6. Uncheck the box that says "Allow the computer to turn off this device to save power".
7. Click OK.
8. Close Device Manager.

After doing this, your Wi-Fi should stop dropping. Try browsing for 10-15 minutes. If it drops again, move to Fix #3.

Note on desktop PCs: Even on a desktop plugged into the wall, Windows might still try to turn off the Wi-Fi card. I've seen it. Unchecking this box is safe and won't hurt battery life since there isn't any.

Fix #3: Reinstall the Wi-Fi driver the right way (15+ minutes, catches the rest)

This is the nuclear option, but it's the one that works when the first two fail. A Windows update can corrupt the driver or install an incompatible version. Removing it and letting Windows reinstall a clean copy almost always fixes the issue.

1. Open Device Manager again (Windows key + X, then Device Manager).
2. Expand Network adapters and find your Wi-Fi adapter (same one as Fix #2).
3. Right-click the Wi-Fi adapter and choose Uninstall device.
4. A checkbox appears that says "Delete the driver software for this device". Check that box. This is the step most people miss. Without it, Windows just reinstalls the same broken driver.
5. Click Uninstall. The screen might flash or go black for a second. That's normal. Your Wi-Fi will disappear from the network list.
6. Restart your computer now. Do not try to scan for hardware changes or click "Action > Scan for hardware changes". A clean restart forces Windows to detect the missing adapter and download a fresh driver from its update cache or Windows Update.

After the restart, your Wi-Fi should be back. It might take 1-2 minutes for the network list to appear after the desktop loads. That's normal – Windows is installing the driver in the background.

Test your connection for at least 30 minutes. If it still drops, you might have a failing Wi-Fi card. But honestly, I've only seen that happen maybe 5 times out of hundreds of these calls. The reinstall fixes the rest.

One more thing: If you have a USB Wi-Fi adapter (like a TP-Link or Netgear dongle), unplug it, go to the manufacturer's website, download the latest driver for your specific model and Windows 11, then plug it back in and run the installer. The steps above apply to internal cards only.

When to call your ISP or buy a new adapter

If none of these three fixes work, and you've also tried rebooting your router (unplug power for 30 seconds), you might have a hardware issue. Run this command in Command Prompt as admin: ping -t 8.8.8.8 and watch if the drops are always there or only on Wi-Fi. If a wired connection (Ethernet) stays solid, your Wi-Fi card is dying. If both drop, it's your router or ISP. Replacements for internal Wi-Fi cards run about $20-40. USB adapters are $15-25. Don't replace the whole laptop.
