How to Fix Wi-Fi and Bluetooth Not Working After Sleep in Windows 10

If your Wi-Fi and Bluetooth stop working after Windows 10 wakes from sleep, that’s a common power management issue. It usually happens because Windows is turning off network adapters to save power or due to outdated drivers.
Here’s a complete fix guide — go step by step:

Step-by-Step Fix for Wi-Fi and Bluetooth Loss After Sleep

STEP 1: Disable Power Saving for Network and Bluetooth Adapters

1. Press Windows + X → select Device Manager.

2. Expand Network adapters → right-click your 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.

6. Repeat the same for your Bluetooth adapter (under Bluetooth section).

STEP 2: Change Power Plan Settings

1. Press Windows + R, type control, and press Enter.

2. Go to Hardware and Sound → Power Options.

3. Click Change plan settings next to your selected plan.

4. Click Change advanced power settings.

5. Expand Wireless Adapter Settings → Power Saving Mode.

   • Set both On battery and Plugged in to Maximum Performance.

6. Expand USB settings → USB selective suspend setting → Set both to Disabled.

7. Click Apply → OK.

   

STEP 3: Update or Reinstall Drivers

1. Open Device Manager again.

2. For both Wi-Fi and Bluetooth adapters, right-click → Update driver →
   Search automatically for drivers.

3. If no update is found:

   • Visit your laptop or motherboard manufacturer’s website.

   • Download and install the latest Wi-Fi and Bluetooth drivers manually.

4. Reboot your PC.

STEP 4: Reset Network Stack (if still broken)

Run these commands in Command Prompt (Admin):

Then restart your PC.

STEP 5: Disable “Fast Startup”

1. Go to Control Panel → Power Options → Choose what the power buttons do.

2. Click Change settings that are currently unavailable.

3. Uncheck Turn on fast startup (recommended).

4. Save and reboot.

STEP 6: Check BIOS / UEFI Power Settings (optional)

If nothing else works:

• Enter BIOS/UEFI (press Del, F2, or Esc during boot).

• Look for Power Management or Advanced → make sure Wake from USB, Wireless LAN, and Bluetooth are enabled.

After these steps:

Your Wi-Fi and Bluetooth should reconnect automatically after sleep or hibernation.
