How to Fix Wi-Fi That Keeps Disconnecting on Windows 11
Quick answer
If the icon actually disconnects (not merely "No Internet" while still showing the network name), this is a drop, not [Wi-Fi connected but no internet](/guides/wifi-connected-but-no-internet). Check whether phones drop too. If only the PC drops, turn off power saving on the Wi-Fi adapter, sit closer to the router for a test, and update the driver from Windows Update or the PC maker. Skip "Wi-Fi booster" apps.
Quick diagnosis
If several of these match what you see, you are in the right guide.
- Wi-Fi connects, then drops to "Disconnected" or starts scanning again
- The network icon flickers; you re-enter the password often
- Drops happen when the laptop sleeps, then wakes
- Other devices stay online while this PC drops
Possible causes
- The adapter is allowed to sleep to save power
- Weak signal, interference, or a busy channel
- A Wi-Fi driver that does not match the hardware
- The router is rebooting or changing bands (2.4 / 5 GHz)
- Windows is switching between Wi-Fi and a broken Ethernet or VPN
What you need
- A second device on the same Wi-Fi
- Router you can restart
What this problem usually means
Connected-but-dead and keep-disconnecting look similar in frustration and are diagnosed differently. The first stays associated with the access point and cannot reach websites. The second loses the association: Windows goes back to looking for networks. Mixing those two checklists wastes time.
If Windows never joins and reports that it cannot connect, use Windows cannot connect to this network.
Before you start
- Note whether drops happen in one room only. Distance is still the most common wireless problem.
- Temporarily forget a VPN or disable Ethernet if a dock cable is half-connected.
- Use the Internet Connection Troubleshooter if you are unsure which symptom you have.
Quick fixes
1. Test next to the router
Sit in the same room as the router for 15 minutes of normal use. If drops stop, the adapter and Windows are probably fine; the path through walls is not. A mesh node or Ethernet to a closer access point is the real fix, not a Windows slider.
2. Stop the adapter from sleeping
- Device Manager → Network adapters → your Wi-Fi device → Properties → Power Management.
- Uncheck "Allow the computer to turn off this device to save power" if it is present.
- Settings → System → Power → uncheck or avoid aggressive sleep while you test (especially "Disconnect from the network when I go to sleep" style options if shown on your build).
Step-by-step troubleshooting
Other devices versus this PC
If phones drop at the same moment, restart the router (power out for a full minute). ISP or router firmware is then more likely than Windows. If phones are stable, stay on this PC: driver, power saving, and airplane-mode toggles.
Forget the network and join again
Settings → Network & internet → Wi-Fi → Manage known networks → Forget, then reconnect. This clears a bad saved profile. It does not fix a dying radio. Use the real password; repeated failures after Forget belong on the cannot connect guide.
Driver from a trustworthy source
Windows Update → Optional updates sometimes include a newer adapter driver. PC-maker support pages (Dell, HP, Lenovo, ASUS) are the other legitimate source. Avoid driver-updater utilities and random Device Manager "update from the internet" sites. After a driver change, reboot and retest in the same room, then in the problem room.
2.4 GHz versus 5 GHz
If the router shows two names, try the other band for a day. 5 GHz is often more stable near the router and drops sooner through walls. 2.4 GHz reaches farther and collides with neighbors and microwaves. That is a radio tradeoff, not a Windows bug.
Who drops, and where?
Choose an answer. The next question appears below, no account or download required.
Restart the router. If it continues, the ISP or the access point is unstable. Windows settings will not repair the whole house.
Treat it as signal. Test next to the router. If that is stable, improve coverage rather than resetting Windows network settings first.
Power Management on the adapter, then a vendor driver. If Ethernet is solid and Wi-Fi still drops at one meter, the laptop radio is more likely.
How to know the problem is fixed
The PC stays associated for a typical work session in the room where it used to drop, including after sleep if that was the trigger. One lucky hour next to the router does not count if the problem was the bedroom.
If the problem continues
A USB Wi-Fi adapter you already own is a fair hardware test. If USB Wi-Fi is stable and the built-in adapter is not, the onboard radio or antenna cable is more likely than a missing Windows tweak. Network reset is a later step; it is heavy-handed for a power-saving checkbox.
When this may be hardware failure
Drops in every building, on every router, with a current vendor driver, make a failing wireless card or antenna more likely. Confirm with a USB adapter if you can. That is not proof by itself, a badly installed driver can look the same until you use a different adapter.
Common mistakes to avoid
- Resetting all network settings before checking distance and adapter power saving.
- Installing a "Wi-Fi booster" or MAC-spoofer from an ad.
- Treating "Connected, no internet" as a disconnect. Different guide.
Frequently asked questions
Why does it drop when the laptop lid closes or it sleeps?
Windows may power down the radio. If the drop mostly happens after sleep or lid close, use [internet disconnects after sleep](/guides/internet-disconnects-after-sleep-windows). Waking to a different access point in a mesh can also look like a drop.
Should I change DNS to stop disconnects?
DNS does not keep you associated with Wi-Fi. Change DNS when names fail while you stay connected, see [change DNS](/guides/change-dns-server-windows-11). It will not stop the icon from going to Disconnected.
