WiFi keeps dropping on Windows 10/11 laptops

Your laptop drops WiFi every few minutes, especially in meetings. Here's the real fix—stop the power-saving nonsense and update the right driver.

When this happens

You're on a Zoom call or streaming a video, and suddenly the WiFi icon shows a yellow triangle. The connection drops for 10–30 seconds, then reconnects. Sometimes it happens every 2 minutes. Sometimes every hour. It's maddening, especially when you're in the middle of something important.

I see this mostly on Dell XPS 13, Lenovo ThinkPad X1 Carbon, and HP Spectre laptops running Windows 10 22H2 or Windows 11 23H2. The trigger is almost always the WiFi adapter's power-saving feature being too aggressive, or a driver that Microsoft Update replaced with a generic one.

Root cause

Windows has a setting called "Power Management" that lets the OS turn off your WiFi adapter to save battery. Sounds good on paper. In reality, it kills the connection the moment the laptop sips less power—like when you stop typing for a few seconds. The adapter goes into a low-power state, then can't wake up fast enough when data starts flowing again.

The second cause is a bad driver. Microsoft Update often pushes generic drivers that work OK but not great. Your adapter's manufacturer (Intel, Realtek, Qualcomm) has specific drivers that handle signal drops and roaming better. I've had clients whose WiFi would drop every 90 seconds until we swapped the driver.

The fix (two steps, do both)

Step 1: Turn off power saving for the WiFi adapter

  1. Press Windows Key + X and select Device Manager.
  2. Expand Network adapters.
  3. Right-click your WiFi adapter (it'll say something like "Intel Wi-Fi 6 AX201" or "Realtek 8822CE") and choose Properties.
  4. Go to the Power Management tab.
  5. Uncheck "Allow the computer to turn off this device to save power."
  6. Click OK. No reboot needed.

That's the single most effective change. I've fixed dozens of laptops with this alone. Windows is supposed to handle this intelligently, but it doesn't. Turn it off.

Step 2: Install the correct driver from the manufacturer

Don't trust the driver Windows Update gives you. Go straight to the source.

  1. Open Device Manager again and right-click your WiFi adapter.
  2. Choose Properties > Details tab > from the dropdown select Hardware Ids.
  3. You'll see something like VEN_8086&DEV_06F0. The VEN is vendor (8086 = Intel, 10EC = Realtek), the DEV is the model.
  4. Go to the vendor's support site and grab the latest driver for your exact chip. Intel has a handy Intel Driver & Support Assistant that auto-detects.
  5. If you have an Intel adapter, run Intel's driver update tool. It's painless.
  6. For Realtek, check your laptop manufacturer's support page (Dell, Lenovo, HP) and download the Realtek WiFi driver listed for your model.
  7. Install the driver, reboot.

I had a client last month whose WiFi died every time they walked past the break room microwave. The Intel driver from Windows Update was from 2021. The Intel tool found a 2024 driver. Problem gone.

What to check if it still fails

If you did both steps and the WiFi still drops, look at these:

  • Channel congestion: Open a command prompt and run netsh wlan show all. See what channel your network is on. If it's channel 6 or 11 and every neighbor is on the same channel, change your router's channel to a less crowded one (1, 2, 3, 4, 5, 7, 8, 9, 10—avoid overlapping).
  • 2.4 GHz vs 5 GHz: If you're on 2.4 GHz, try switching to 5 GHz in your router settings. 2.4 GHz has more interference from Bluetooth, microwaves, baby monitors. 5 GHz is cleaner but has less range.
  • Router firmware: Log into your router (usually 192.168.1.1 or 192.168.0.1) and check for firmware updates. I've seen Asus routers from 2018 that need updates to handle newer laptop adapters.
  • IP address conflict: Rare, but run ipconfig /release then ipconfig /renew from an admin command prompt to get a fresh IP lease.
  • Antivirus or VPN: Some aggressive antivirus suites (looking at you, McAfee) scan WiFi traffic and cause drops. Temporarily disable it to test. VPNs can also cause flaky connections—try disconnecting the VPN.

If none of that works, your adapter might be physically failing. I've had three ThinkPads where the internal antenna cable was loose. Pop the bottom cover, reseat the white and black wires on the card. Or just buy a $20 USB WiFi adapter (TP-Link Archer T2U Nano works well) and move on.

Bottom line: power saving off + correct driver fixes 9 out of 10 cases. Don't overthink it.
