Fix Mobile Tethering Keeps Disconnecting on Windows 11

If your Windows 11 PC keeps dropping the mobile hotspot connection, the fix is usually a combination of power settings, driver updates, and Wi-Fi adapter configuration. Start by disabling the “Allow the computer to turn off this device to save power” option for your Wi-Fi adapter, then update the driver and adjust the power plan. Below is a complete troubleshooting guide that addresses the most common causes and step-by-step solutions.

Why Tethering Disconnects on Windows 11

Mobile tethering (sharing your phone’s cellular data via Wi-Fi, Bluetooth, or USB) is a convenient fallback, but Windows 11 can drop the connection for several reasons:

• Power saving: Windows may put the Wi-Fi adapter to sleep when idle, even if you’re actively using the connection.
• Driver issues: Outdated or incompatible Wi-Fi drivers can cause instability.
• Wi-Fi adapter settings: Aggressive roaming or power management features can interrupt the link.
• Phone-side settings: Your phone’s hotspot may have a timeout or power-saving mode.
• Interference: Other devices or physical obstacles can weaken the signal.
• Windows updates: A recent update might have changed network settings.

Quick Fixes to Try First

These take less than a minute and resolve many disconnection issues:

1. Toggle Wi-Fi off and on: Click the network icon in the taskbar, turn off Wi-Fi, wait 5 seconds, then turn it back on.
2. Forget the network: Go to Settings > Network & Internet > Wi-Fi > Manage known networks, select your hotspot, click Forget, then reconnect by entering the password again.
3. Restart both devices: Reboot your PC and your phone—this clears temporary glitches.
4. Check the hotspot signal: Make sure your phone has a strong cellular signal; a weak signal can cause the hotspot to drop.

Disable Wi-Fi Power Saving

Windows 11 is aggressive about saving power, and it often turns off the Wi-Fi adapter to do so. To stop this:

1. Press Win + X and select Device Manager.
2. Expand Network adapters, right-click your Wi-Fi adapter (usually named “Intel Wi-Fi” or “Realtek”), 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 and restart your PC.

This is the single most effective fix for random disconnects, especially when your PC is on battery power.

Update or Reinstall the Wi-Fi Driver

An outdated or corrupt driver is another common culprit. Here’s how to update it:

1. Open Device Manager again.
2. Right-click your Wi-Fi adapter and select Update driver.
3. Choose Search automatically for drivers. If Windows finds none, go to your PC manufacturer’s support website and download the latest driver for your model.
4. If the problem persists, right-click the adapter and select Uninstall device (check “Delete the driver software for this device” if available), then restart. Windows will reinstall the driver automatically.

Adjust Wi-Fi Adapter Advanced Settings

Some Wi-Fi adapters have advanced settings that can cause disconnects. To change them:

1. In Device Manager, right-click your Wi-Fi adapter and select Properties.
2. Go to the Advanced tab.
3. Look for these settings and change them as follows (if present):
   • Roaming Aggressiveness: Set to Lowest or Disabled.
   • Power Save Mode: Set to Maximum Performance or Disabled.
   • Preferred Band: Set to 2.4 GHz (hotspots often use this band for better range).
   • Wake on Magic Packet: Disable if you don’t need it.
4. Click OK and restart.

Note: Not all adapters have these options; if you don’t see them, skip this step.

Change Power Plan Settings

Windows power plans can also affect Wi-Fi stability. To adjust:

1. Open Control Panel (search for it in the Start menu).
2. Go to Hardware and Sound > Power Options.
3. Next to your active plan, click Change plan settings.
4. Click Change advanced power settings.
5. Expand Wireless Adapter Settings > Power Saving Mode.
6. Set both On battery and Plugged in to Maximum Performance.
7. Click Apply and OK.

Phone-Side Settings to Check

Your phone is half the equation. Common phone settings that cause disconnects:

• Hotspot timeout: Many Android phones have a “Wi-Fi hotspot timeout” that turns off the hotspot after a period of inactivity. Set it to “Always” or “Never”.
• Power saving mode: On both Android and iPhone, battery saver can disable the hotspot. Turn it off while tethering.
• Band selection: If your phone offers a 5 GHz hotspot, try switching to 2.4 GHz—it’s more stable over distance.
• Device limit: Ensure your PC isn’t being kicked off because the hotspot has a max device limit.

When to Use USB or Bluetooth Tethering

If Wi-Fi tethering keeps failing, USB or Bluetooth tethering are more stable alternatives:

• USB tethering: Plug your phone into the PC with a USB cable. It’s the most stable and also charges your phone. Enable it in your phone’s hotspot settings. On Windows 11, it appears as a new network adapter.
• Bluetooth tethering: Pair your phone with the PC, then enable Bluetooth tethering on the phone. It’s slower but uses less battery. On Windows, go to Settings > Bluetooth & devices, add the phone, then connect via the network icon.

Both methods bypass Wi-Fi entirely, so they’re immune to Wi-Fi driver and interference issues.

Frequently Asked Questions

Why does my hotspot disconnect every few minutes?

The most common cause is the Wi-Fi adapter power-saving feature. Disable it in Device Manager as described above. Also check your phone’s hotspot timeout setting—many phones default to a 10-minute inactivity cutoff.

Can a VPN cause tethering disconnects?

Yes. VPN software can interfere with network routing and cause the connection to drop, especially if it has a kill switch. Try disconnecting the VPN temporarily to see if the issue stops.

Does Windows 11 have a known issue with mobile hotspots?

Some users report disconnects after certain Windows updates, but there’s no universal known issue. The fixes above address the most reported causes. If the problem started after a specific update, you can roll it back via Settings > Windows Update > Update history > Uninstall updates.

Is there a way to keep the hotspot from sleeping on Android?

Yes. On most Android phones, go to Settings > Hotspot & tethering > Wi-Fi hotspot and look for “Timeout” or “Auto-off”. Set it to “Always” or “Never”. Also disable battery optimization for the hotspot app.

Why does tethering work on another PC but not mine?

If the same hotspot works on another device, the problem is specific to your PC’s Wi-Fi adapter, driver, or settings. Follow the driver update and power-saving steps—they resolve the majority of such cases.

Can I use a third-party app to keep the connection alive?

There are network keep-alive tools that send periodic pings to prevent idle timeouts, but they’re rarely necessary if you’ve disabled power saving on both the PC and phone. Try the built-in fixes first.
