Wi-Fi Keeps Dropping on Windows 11: 3 Fixes That Actually Work

Start Here: 30-Second Power Drain

You're on a call or in the middle of a download and suddenly the Wi-Fi icon turns into a globe. Then it reconnects after ten seconds. This is the most common Windows 11 Wi-Fi drop scenario. Before you dive into settings, do a proper power drain. This clears the network hardware's internal state, which often gets stuck after a sleep/wake cycle or a partial power outage.

1. Shut down your laptop or PC completely. Not restart – shut down.
2. If it's a laptop, unplug the power adapter and remove the battery if it's removable. Most modern laptops have sealed batteries – if you can't remove it, that's fine.
3. Press and hold the power button for 15 seconds. You'll see the screen flicker or the fans spin briefly, then stop. This discharges any leftover power in the capacitors.
4. Wait 30 seconds.
5. Plug everything back in and turn the machine on.

After booting up, connect to Wi-Fi and watch it for 10 minutes. If the connection holds, you're done. If it drops again, move to the next fix.

Moderate Fix: Roll Back or Update the Wi-Fi Driver (5 Minutes)

Windows 11's automatic driver updates are usually helpful, but they've also broken Wi-Fi for a lot of people. I've seen it happen with Intel AX200 and Realtek RTL8821CE adapters specifically. The fix is to either roll back to a driver that worked or install the latest one from the manufacturer's website – skipping the one Windows pushed.

Check and roll back the driver

1. Press Win + X and select Device Manager.
2. Expand Network adapters.
3. Find your Wi-Fi adapter. It usually has “Wi-Fi” or “Wireless” or “802.11” in the name.
4. Right-click it and select Properties.
5. Go to the Driver tab.
6. If the Roll Back Driver button is clickable, click it and follow the prompts. It will ask you why – pick any reason and hit Yes.

After rolling back, you'll get a message that the previous driver has been reinstalled. Restart your PC. Then test the connection. If the rollback button is grayed out, that means there's no previous driver to go back to. In that case, you need to get the driver directly from the chipset or laptop manufacturer.

Install a clean driver from the manufacturer

1. Go to your laptop manufacturer's support site (Dell, HP, Lenovo, etc.) or if you built your desktop, go to the Wi-Fi card vendor's site (Intel, Realtek, Killer).
2. Search for your exact model and download the latest Wi-Fi driver for Windows 11. Be careful to get the 64-bit version – most systems are 64-bit.
3. Before installing, run Device Manager again, right-click your Wi-Fi adapter, and select Uninstall device. Check the box that says Delete the driver software for this device.
4. Restart your PC. Windows will install a generic driver, but that's okay. Now run the installer you downloaded. It will replace the generic one.

After the install, restart one more time. Test for at least 15 minutes. If the drops persist, the issue is likely power management – the next fix.

Advanced Fix: Disable Power Saving on the Adapter (15+ Minutes)

Windows 11 has a hidden power-saving feature that tells your Wi-Fi adapter to sleep when it thinks you're not using it. The problem is that it's overly aggressive. You'll see this especially on laptops where battery saving kicks in, but it happens on desktops too. This fix involves two settings – one in Device Manager and one in the Power Options control panel.

Step 1: Device Manager power management

1. Open Device Manager again.
2. Find your Wi-Fi adapter, right-click it, and select Properties.
3. Go to the Power Management tab.
4. Uncheck Allow the computer to turn off this device to save power.
5. Click OK.

That alone fixes it for many people. But don't stop there – the second setting is just as important.

Step 2: Change the wireless adapter power mode in Power Options

1. Press Win + R, type powercfg.cpl and hit Enter. That opens the classic Power Options window.
2. Click Change plan settings next to your active plan (usually Balanced).
3. Click Change advanced power settings.
4. In the list, scroll down to Wireless Adapter Settings.
5. Expand it, then expand Power Saving Mode.
6. Set both On battery and Plugged in to Maximum Performance. If you don't want to drain battery faster, set On battery to Medium Power Saving – but for a stable connection, Maximum Performance is the real fix.
7. Click Apply and OK.

Now test your connection for a full hour. If it drops after this, the problem isn't power management.

Step 3: Network reset (nuclear option)

If you've done both power settings and the driver is clean, but the drops continue, run a network reset. It's a bit heavy-handed – it will forget all your Wi-Fi passwords and VPN connections – but it rebuilds the entire networking stack from scratch.

1. Open Settings (Win + I).
2. Go to Network & internet.
3. Scroll down and click Advanced network settings.
4. Click Network reset.
5. Click Reset now. Your PC will restart after five minutes.

After the restart, you'll need to reconnect to your Wi-Fi network and re-enter any VPN credentials. This is the last resort – if this doesn't help, you're likely looking at a hardware issue like a failing adapter or interference from a neighbor's router on the same channel. In that case, try changing your router's wireless channel to 1, 6, or 11 – the non-overlapping ones.

Why This Happens: What's Actually Going On

The three fixes above cover 90% of the Wi-Fi drop issues I've seen in help desk work. The most common culprit is the power management setting in Device Manager – it's enabled by default on almost every Windows 11 laptop. The second most common is a bad driver update that Windows pushed automatically. The network reset is for when the system's network configuration is corrupted – like after a failed VPN client install or a sudden shutdown during an update.

If you're on a public network or using a router provided by your ISP, the problem could also be on the router side. But before blaming the router, try all three steps in order. They cost you a few minutes each, and they work.
