Why Does My Laptop Keep Disconnecting from Wi-Fi? (Windows 11)

This one has a very particular feel to it. The Wi-Fi connects perfectly, you get to work, and then a few minutes later the little globe or "no internet" icon appears, the connection drops, and a moment later it reconnects on its own — over and over, all day. Web pages stall, video calls freeze and come back, downloads die halfway. It's not that you can't get online; it's that you can't stay online. And because it reconnects by itself, it feels like there's nothing to actually fix.

There usually is, and on a Windows 11 laptop it's usually the same thing. Before we get to it, one thing to skip: the "driver updater," "network booster," and "Wi-Fi fixer" tools that fill these search results. The single most common fix for a laptop that keeps dropping Wi-Fi is a free setting built into Windows that the tool vendors would rather you not know about — because if you knew, you wouldn't pay for their app. Everything below is a real step, and nearly all of it is free.

First: is it just this laptop, or the whole house?

This one question saves you from fixing the wrong thing, so answer it before you change a single setting. If other devices on the same Wi-Fi — your phone, a tablet, a smart TV, a partner's laptop — stay connected fine while only this one laptop keeps dropping, the problem is on the laptop, and the settings below are where the fix lives. If everything in the house drops at the same time, the laptop is innocent and the trouble is your router, your internet line, or your ISP — a different hunt entirely.

A quick way to tell: next time your laptop drops, glance at your phone on the same Wi-Fi. Still connected and loading pages? It's the laptop. Dropped too? It's the network, and it's worth reading our guide on Wi-Fi that's connected but has no internet, or the one on why Wi-Fi gets slow, and checking whether an aging or overheating router needs a reboot or a firmware update. The rest of this article is about the far more common case: one laptop, dropping on its own, while everything else stays online.

The number-one laptop fix: stop Windows powering off the Wi-Fi

Here's the setting that fixes this for most people, and almost nobody stumbles onto it by accident. To save battery, Windows is allowed to switch your Wi-Fi adapter off when it decides you're not using it — and then switch it back on when you are. On a lot of laptops it gets this wrong and cuts the radio during normal use, which lands on your screen as a connection that keeps dropping and reconnecting for no visible reason. Turning that permission off is the fix, and it takes under a minute.

Right-click the Start button and open Device Manager. Expand "Network adapters," and find your Wi-Fi adapter — it's the one with "Wireless," "Wi-Fi," "Wi-Fi 6," or "802.11" in its name (Intel, Realtek, Qualcomm, and Broadcom are common makers). Right-click it, choose Properties, and click the "Power Management" tab. Untick "Allow the computer to turn off this device to save power," click OK, and restart the laptop. That's it. The only trade-off is a tiny bit more battery drain — a few minutes less per charge — in exchange for a Wi-Fi connection that actually stays up, which on most laptops is a trade well worth making.

While you're at it: the power plan's hidden Wi-Fi setting

There's a second, related power setting in a different place that catches the drops the first one misses, especially on a laptop running on battery. Open the Start menu, search for "Edit power plan," and click "Change advanced power settings." In the list that pops up, expand "Wireless Adapter Settings," then "Power Saving Mode," and set it to "Maximum Performance" — for both "On battery" and "Plugged in" if you want it rock-solid everywhere. This tells Windows to stop throttling the Wi-Fi radio to save power, which is the same class of problem as the Device Manager setting, just controlled separately.

One more, only if your laptop uses a plug-in USB Wi-Fi adapter (a little dongle) rather than the built-in card: in that same advanced list, expand "USB settings" and "USB selective suspend setting" and set it to Disabled. Windows suspends idle USB devices to save power, and it can catch a USB Wi-Fi stick mid-use and drop your connection. If your Wi-Fi is the built-in internal kind — which it is on almost every laptop — you can leave USB selective suspend alone; it only matters for external USB adapters.

Update the Wi-Fi driver — or roll back a bad one

If the power settings don't settle it, the Wi-Fi driver is the next suspect. The driver is the small piece of software that lets Windows talk to your wireless card, and Wi-Fi chip makers (Intel, Realtek, Qualcomm) don't always keep pace with Windows updates — so you can end up with a driver that's buggy or mismatched and drops the connection at random. The reliable way to update it isn't a paid "driver updater" tool; it's to go to your laptop maker's support site (Dell, HP, Lenovo, ASUS, Acer), type in your model, and download the current wireless or Wi-Fi driver straight from them. Install it and restart.

The flip side matters just as much: if your Wi-Fi was fine and started dropping right after a Windows update or a driver change, a bad new driver is the likely culprit — and the fix is to go backwards, not forwards. In Device Manager, right-click the Wi-Fi adapter, choose Properties, open the "Driver" tab, and if "Roll Back Driver" is available, use it to return to the version that worked. A corrupted or wrong network driver is a common enough cause of connection trouble that we wrote a whole guide on spotting it, and it's worth a read if updating and rolling back both come up empty.

The "flip-flopping between networks" trap

Sometimes the laptop isn't losing Wi-Fi so much as it's constantly changing its mind about which Wi-Fi to use, and each switch reads as a drop. Two things cause this. The first is having "Connect automatically" ticked on several networks — a neighbor's open hotspot, an old work network, a phone hotspot — so the laptop keeps hopping between them. Fix it by leaving "Connect automatically" on only for your own home network and turning it off for the rest, and by telling Windows to "Forget" any network you don't actually use.

The second is a modern-router quirk. Many routers broadcast the 2.4GHz and 5GHz bands under the same network name, and mesh systems have several units sharing one name, so your laptop is meant to roam smoothly between them — but some laptops handle that badly and stutter at every hand-off, dropping for a second each time. If your drops happen as you move around the house, or the connection is worst at the edge of one room, try "forgetting" the network and rejoining it, and if your router lets you split the 2.4GHz and 5GHz bands into two separate names, doing so and joining the 5GHz one by hand near the router can steady a flaky laptop.

The reset that fixes a tangled network setup

If you've worked through the power settings, the driver, and the network list and the laptop still drops, a full network reset clears out a corrupted or tangled networking setup that no single toggle will. Go to Settings > Network & internet > Advanced network settings > Network reset, and confirm. Windows removes and reinstalls every network adapter and returns all the networking pieces to their factory defaults, which is exactly what you want when something deep in the stack has gone wrong.

One heads-up before you do it: a network reset wipes your saved Wi-Fi networks and any VPN settings, so the laptop will forget your Wi-Fi password and you'll have to type it back in afterward — have it handy. Because it clears everything at once, save this for after the targeted fixes above rather than as your first move; if the power-management box was the real problem, a reset is a lot of collateral damage for something one unticked checkbox would have solved.

If the whole house drops, look at the router

Circle back to that first question. If your laptop dropping is really the whole network dropping — everything goes at once — no amount of laptop tinkering will help, and the router is where to look. Give it the basics first: unplug it for thirty seconds and power it back up, check for a firmware update in its settings or app, and make sure it isn't tucked somewhere hot and airless, because an aging or overheating router drops connections when it gets warm. There's a real Southern California angle to that last point — a router baking on a sunny shelf or in a stuffy closet through a Valley summer afternoon is a genuine cause of afternoon drop-outs.

Two more router-side causes worth knowing. In a dense apartment building — think Koreatown, Hollywood, or a coastal condo stack — dozens of neighboring networks crowd the airwaves, especially on the older 2.4GHz band, and the interference shows up as drops; rebooting the router lets it pick a clearer channel, and joining the 5GHz band avoids the worst of the congestion. And if the drops hit every device in the house at set times or across the whole neighborhood, it may be the internet line or your ISP rather than your gear at all — check the provider's outage map and give them a call before you buy new hardware.

How we can help

The honest short version: don't buy a "Wi-Fi fixer" app for a laptop that keeps dropping the connection — the real fix is almost always free and hidden in plain sight. First check whether it's only this one laptop or the whole house. If it's the laptop, untick "Allow the computer to turn off this device to save power" in Device Manager (that alone fixes most cases), set the power plan's Wireless Adapter "Power Saving Mode" to Maximum Performance, update or roll back the Wi-Fi driver from your laptop maker, tidy up the "connect automatically" network list, and only then fall back to a full Network reset. If it's the whole house, it's the router or the ISP, not the laptop.

When that doesn't do it — a genuinely failing Wi-Fi card, a driver mess that won't clear, or a network that drops no matter what you try — that's the everyday sort of thing we sort out for homes and small businesses across Southern California and the Coachella Valley. We'll work out whether it's the laptop, the router, or the line, get the right driver on there, replace a dying wireless card if that's the cause, and set your Wi-Fi up so it stays connected. Because we don't sell you a subscription app, we've no reason to point you at anything but the setting or the part that actually fixes it.
