How to Fix Wi-Fi That Keeps Dropping on Windows 11

Updated October 26, 2026 · 6 min read

If your Windows 11 laptop keeps dropping Wi-Fi while every other device stays connected, the problem is almost always on the laptop — not your router. Work through these five fixes in order. Most people are back online by fix #2.

Quick fix first: restart the network stack

1. Click the Wi-Fi icon, then Forget your network.
2. Restart the laptop (a real restart, not sleep).
3. Reconnect and re-enter your Wi-Fi password.

If it holds for a day, you were done. If it drops again, keep going.

Fix 1: Stop Windows from turning the adapter off

1. Right-click Start → Device Manager → Network adapters.
2. Right-click your Wi-Fi adapter → Properties → Power Management.
3. Uncheck "Allow the computer to turn off this device to save power."
4. Click OK and restart.

This is the single most common cause. Windows power-saves the adapter to sleep, and some drivers never wake it cleanly.

Fix 2: Update (or roll back) the Wi-Fi driver

1. In Device Manager, right-click your Wi-Fi adapter → Update driver → Search automatically.
2. If Windows says it's already current, check your laptop maker's support site (Dell, HP, Lenovo) for a newer driver — their versions are often months ahead.
3. If the drops started right after an update, use Roll Back Driver instead.

Fix 3: Reset the network stack

Open Terminal as administrator and run these, one at a time:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Then restart. This clears corrupted network settings without touching your files.

Fix 4: Switch to the 5 GHz band (or 2.4 GHz)

In your router's Wi-Fi settings, give the 2.4 GHz and 5 GHz networks different names, then connect to each in turn. 5 GHz is faster but shorter range; 2.4 GHz reaches further through walls. If one band is stable and the other isn't, you've found your answer — and possibly a dying router radio.

Fix 5: If it still drops — it's probably hardware

Try a cheap USB Wi-Fi adapter (below). If the USB adapter holds a rock-solid connection where the built-in one drops, the internal card or its antenna wires are the problem. Replacing an internal card is a $20 part and a 15-minute job on most laptops — or the USB adapter is a perfectly good permanent fix.

If none of this worked

Check whether the drops happen on other networks (a café, a friend's house). Drops everywhere = your laptop. Drops only at home = your router — and that's a different article: see our router buying guide.
