Wi-Fi Keeps Dropping on Windows 11? Try These Fixes in Order

The 30-Second Fix: Forget and Rejoin the Network

You'd be surprised how often Wi-Fi drops come down to a corrupted or stale network profile. Windows saves your Wi-Fi settings, including the password and security type, but if that profile gets out of sync with the router, the connection will keep dying. What's actually happening is the adapter associates, gets a handshake error, and silently drops. Windows doesn't always show an error—it just disconnects.

1. Click the Wi-Fi icon in the system tray.
2. Select Network & Internet settings.
3. Click Wi-Fi, then Manage known networks.
4. Find your network, click Forget.
5. Reconnect by clicking the network icon and entering your password.

Do this once. If the drop happens again within an hour, move to the next step. Don't bother with this fix more than twice—if it didn't stick, the profile wasn't the problem.

The 5-Minute Fix: Update (or Roll Back) Your Wi-Fi Driver

Driver issues are the second most common cause. Windows 11 has a habit of pushing updates that break wireless adapters, especially on Intel and Realtek chips. The reason step one fails here is that the driver is misreporting signal strength or failing to handle power state changes, which has nothing to do with the network profile.

Here's what to do:

1. Press Win + X and select Device Manager.
2. Expand Network adapters.
3. Right-click your Wi-Fi adapter (look for Intel, Realtek, or Broadcom) and select Update driver.
4. Choose Search automatically for drivers. If that finds nothing, go to the manufacturer's website and grab the latest driver manually.

Now the twist: if you recently updated the driver and then the drops started, you're better off rolling back. Right-click the adapter, go to Properties > Driver tab, and click Roll Back Driver. That reverts to the previous version that worked. I've fixed more machines with a rollback than with an update.

After you update or roll back, reboot and test. Still dropping? Move on.

The 15+ Minute Fix: Power Management and Network Reset Done Right

If you're still here, the problem is likely power management or a deeper system networking glitch. Let's handle both.

Step 1: Disable the adapter's power saving

Windows 11 lets your Wi-Fi adapter go to sleep to save battery, but that's often what kills the connection. The adapter shuts off its radio to save a few milliwatts, and half the time it fails to wake up properly. The reason the connection drops instead of just slowing down is the driver sends a "link down" event to the OS, and Windows treats it as a disconnect.

To turn that off:

1. Open Device Manager again.
2. Right-click the Wi-Fi adapter > Properties.
3. Go to the Power Management tab.
4. Uncheck "Allow the computer to turn off this device to save power."
5. Click OK.

Also check your power plan. Go to Control Panel > Power Options > Change plan settings > Change advanced power settings. Look for Wireless Adapter Settings > Power Saving Mode and set it to Maximum Performance. This matters on laptops especially—on a desktop it's less relevant, but do it anyway.

Step 2: Flush DNS and reset Winsock

Sometimes the issue isn't the radio, it's the TCP/IP stack getting corrupted. A DNS cache that's out of whack can cause connections to time out, which looks like a drop. Winsock is the Windows socket API—if that's corrupted, nothing network-related works reliably.

Run these commands from an admin command prompt (search for "cmd", right-click, "Run as administrator"):

ipconfig /flushdns
netsh winsock reset
netsh int ip reset

Reboot after that. The netsh int ip reset will rewrite your TCP/IP stack to defaults, which can undo any bad proxy or adapter settings that were messing things up.

Step 3: The nuclear option—network reset

If nothing above helped, Windows 11 has a built-in network reset that removes all adapters and reinstall them. It also resets your network settings to defaults, including VPNs and virtual switches. You'll lose saved Wi-Fi passwords and need to reconnect to networks, so only do this if you're okay with that.

1. Go to Settings > Network & Internet > Advanced network settings.
2. Click Network reset.
3. Click Reset now.

After the reset, your PC will restart. When it comes back, you'll see the network adapter freshly installed. Reconnect and test. This fixes the stubborn cases where the driver and power management were fine but the actual network stack was broken.

When to stop and look elsewhere

If you've done all three sections and the Wi-Fi still drops, the problem might not be your PC. Test on your phone. If your phone also drops, it's your router or ISP. That's a whole different article, but at least you've isolated the issue. Don't keep resetting Windows for a router problem—you'll waste an afternoon.

Also, if you're on a 5GHz band and your router has channel width set to 80MHz, try setting it to 40MHz. Some Wi-Fi adapters can't handle DFS channels or wide bands well, and they drop the link when interference appears. You'd need to log into your router's admin page for that, but it's worth a shot if you're comfortable with that level of tweaking.

Bottom line: most Wi-Fi drops on Windows 11 are either a stale profile, a bad driver, or power management turning off the radio. Work through them in order, and stop when the connection stays up for a full day. That's the real test.
