Summary: Wi-Fi drops every few minutes on a laptop or desktop? Fix power management, drivers, and router settings that cause random disconnects in Windows 11.
Recommended app: Network Traffic Monitor & Analyzer — https://www.mytechnician.tech/apps/network-monitor/ (Microsoft Store: https://apps.microsoft.com/detail/9NGCWN2BKVSC?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## The Problem
You join Wi-Fi, browse for a bit, then the icon flips to disconnected—or stays connected but pages stop loading until you toggle Wi-Fi off and on. Laptops on battery are the worst offenders; desktops on USB Wi-Fi dongles run a close second.

> **Connected but pages won't load?** That is usually DNS or a stuck stack—see [fix "No Internet, secured"](https://www.mytechnician.tech/tips/fix-no-internet-secured-wifi/) instead of chasing disconnects.

## Symptoms
* Wi-Fi icon shows disconnected every few minutes, especially on battery.
* Downloads stall mid-file; video calls freeze until you reconnect.
* Phone on the same network stays fine—problem follows one PC.

## The Fix: Step-by-Step

### Step 1: Forget the Network and Rejoin
Stale profiles cause odd handoffs after a router change.
1. **Settings** → **Network & internet** → **Wi-Fi** → **Manage known networks**.
2. Select your network → **Forget**.
3. Reconnect and enter the password. Pick **Private** when Windows asks.

### Step 2: Stop Windows From Turning Off the Adapter
Power saving is the number-one cause on laptops.
1. Right-click **Start** → **Device Manager**.
2. Expand **Network adapters** → right-click your Wi-Fi adapter → **Properties**.
3. Open the **Power Management** tab → uncheck **Allow the computer to turn off this device to save power**.
4. On laptops: **Settings** → **System** → **Power** → set **Plugged in** and **On battery** to **Best performance** while testing (you can dial back later).

### Step 3: Update or Roll Back the Wi-Fi Driver
1. In **Device Manager**, right-click the Wi-Fi adapter → **Update driver** → **Search automatically**.
2. Still dropping? **Properties** → **Driver** tab → **Roll Back Driver** if the button is active (a bad update often started the problem).
3. Last resort: **Uninstall device**, reboot, and let Windows reinstall—or grab the driver from Intel, Realtek, or Qualcomm (not a random third-party site).

### Step 4: Set a Fixed Channel Width (Advanced)
Some Intel adapters fight crowded 5 GHz bands.
1. **Device Manager** → Wi-Fi adapter → **Properties** → **Advanced**.
2. Find **Preferred Band** or **802.11n/ac Wireless Mode** and try **5 GHz only** if you are near the router; try **2.4 GHz** if you are two rooms away.
3. On the router admin page, set a fixed channel (36–48 on 5 GHz, 1/6/11 on 2.4 GHz) instead of **Auto** if neighbors overlap.

### Step 5: Reset the Network Stack
When disconnects started after a Windows update:
1. Open **Terminal (Admin)** (`Win + X`).
2. Run:
   ```cmd
   netsh winsock reset
   netsh int ip reset
   ipconfig /flushdns
   ```
3. Reboot and test on Wi-Fi for at least 30 minutes.

> **Disconnects hard to catch?** You can [track connection drops](https://www.mytechnician.tech/apps/network-monitor/) automatically with Network Traffic Monitor & Analyzer—it timestamps every dropout so you can prove the pattern.

### Step 6: Router and ISP Checks
* Reboot the router (power off 30 seconds).
* Disable **Wi-Fi Protected Setup (WPS)** in router settings—old WPS bugs still cause dropouts.
* If only one band fails, rename 2.4 GHz and 5 GHz SSIDs so Windows does not hop between them.

## When It Is Not the PC
If every device drops at the same time, log into the router or call the ISP. A failing modem or overheating router looks like "Windows Wi-Fi" until you test with a phone on cellular hotspot—if the PC is stable on the phone's hotspot, the home router is the suspect. If the link holds steady but everything is slow, that is a different problem—see [how to speed up a slow internet connection](https://www.mytechnician.tech/tips/speed-up-slow-internet-connection-windows-11/).
