How Do I Fix Windows 11 Wi-Fi Disconnecting Every Few Minutes?

Issue type: Windows system — Wi-Fi disconnects every few minutes then reconnects automatically, causing repeated interruptions

SEO focus: If you are looking for windows 11 wifi disconnecting every few minutes, this guide starts with the fastest diagnosis, then moves to the exact fix that matches the symptom.

Short answer: Repeated short disconnections in Windows 11 are most commonly caused by the Wi-Fi adapter’s power management setting turning the adapter off during light activity to save power. Disabling this setting in Device Manager takes 30 seconds and resolves the disconnects in the majority of cases. If that doesn’t work, the driver’s roaming aggressiveness setting or a DNS timeout issue is the next most likely cause.

Windows 11 Wi-Fi Disconnecting Every Few Minutes: Quick Diagnosis

Pay close attention to when the disconnections happen — the pattern identifies the cause:

Disconnects when the PC is idle or during light activity (reading, watching video), then reconnects when you move the mouse or press a key: This is power management. Windows is instructing the Wi-Fi adapter to enter a low-power state, which drops the connection. Moving the mouse wakes the adapter, which then reconnects. This is the single most common cause of “Wi-Fi drops every few minutes” on Windows 11 laptops and is resolved in one step.

Disconnects at random intervals regardless of activity — even during active downloads or gaming: The adapter is losing the signal and failing over to another access point, or the driver is crashing and recovering silently. Check the roaming aggressiveness setting and whether the driver needs updating.

Connection shows as connected but pages stop loading for 30–60 seconds then resume: This is not a true disconnection — the adapter is connected but DNS lookups are timing out. The adapter icon stays connected in the taskbar but internet access pauses. This is a DNS issue, not a Wi-Fi adapter issue.

Also confirm whether the disconnections happen on both 2.4GHz and 5GHz bands, or only one. If only the 5GHz band drops frequently, the signal strength at your location may be too weak for that band — 5GHz has shorter range than 2.4GHz and drops off faster through walls.

What to do first

1. Disable power management on the Wi-Fi adapter — do this first. Open Device Manager (Win + X > Device Manager) > expand Network adapters > right-click your Wi-Fi adapter > Properties > click the Power Management tab > uncheck “Allow the computer to turn off this device to save power” > click OK. Test over the next 30 minutes. This single change eliminates power-management-related disconnects entirely.
2. Set the Windows power plan away from Power Saver. Go to Settings > System > Power & sleep > Additional power settings. If Power Saver is selected, switch to Balanced. Power Saver aggressively reduces adapter power even when the device is plugged in, overriding the Device Manager setting in some configurations.
3. Adjust the Wi-Fi adapter’s Roaming Aggressiveness setting. In Device Manager, right-click your Wi-Fi adapter > Properties > Advanced tab. Scroll through the Property list and find Roaming Aggressiveness (it may also appear as “Roaming Sensitivity” depending on the driver). Change the value from Medium or High to Lowest. This stops the adapter from constantly scanning for and switching to “better” access points — a behavior that causes repeated brief disconnects when the adapter switches between a router’s 2.4GHz and 5GHz bands. Click OK.
4. Update the Wi-Fi driver. In Device Manager, right-click the Wi-Fi adapter > Update driver > Search automatically. For the most reliable driver, go directly to your laptop or motherboard manufacturer’s support site and download the latest Wi-Fi driver for your exact model. After installing, restart and monitor. If disconnects started after a specific Windows Update, check the Driver tab for the current driver date and consider rolling back to the previous version.
5. Change DNS servers to fix apparent disconnects that are actually DNS timeouts. Open Settings > Network & internet > Wi-Fi > Hardware properties > click Edit next to DNS server assignment > set to Manual > enter 1.1.1.1 (Cloudflare) as Preferred and 8.8.8.8 (Google) as Alternate. Flush DNS afterward: open Command Prompt as Administrator and run ipconfig /flushdns. If the “disconnections” were actually DNS timeouts, this resolves them without touching the adapter settings.
6. Reset Windows network components if the above steps don’t fix it. Open Command Prompt as Administrator and run these commands in order:
   netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /flushdns
ipconfig /renew
   Restart after running all commands. This resets the network stack to a clean state and resolves issues caused by corrupted TCP/IP settings.

Common mistake

Assuming the router or ISP is responsible and spending time resetting the router or calling the ISP before checking the adapter’s power management setting. The router and ISP almost never cause a pattern of brief, regular disconnects that affect only one specific Windows 11 device while other phones, tablets, and computers on the same network stay connected. If every other device on the network stays connected while only the Windows 11 PC drops repeatedly, the problem is entirely on the PC side — start with Device Manager’s power management setting, not the router.

Best next step

If disabling power management, adjusting roaming aggressiveness, and updating the driver all fail to stop the disconnects, the Wi-Fi adapter itself may be developing a hardware fault. As a diagnostic test, purchase an inexpensive USB Wi-Fi adapter (any dual-band USB 3.0 adapter works for testing purposes) and connect through that instead of the built-in adapter. If the USB adapter maintains a stable connection while the built-in one doesn’t, the built-in adapter is failing or has a persistent driver compatibility issue with Windows 11 that the manufacturer hasn’t patched. On a laptop, this means a repair shop or a permanent USB adapter workaround. On a desktop, it means replacing the PCIe Wi-Fi card.

Final check: After applying the steps above, test the same situation again to confirm the windows 11 wifi disconnecting every few minutes problem is actually fixed, not only hidden temporarily.

Quick Q&A

The Wi-Fi disconnects only at night. Is that the ISP or the PC?

Night-only disconnects on one device while others stay connected point to the power management issue — the PC is idle at night and the adapter enters its low-power state. Disabling the “Allow the computer to turn off this device to save power” setting in Device Manager’s Power Management tab resolves it. If all devices on the network drop at night, that’s an ISP or router scheduling issue (some routers reboot on a schedule) — unrelated to Windows.

My Wi-Fi keeps disconnecting but shows full signal strength. Does that mean the signal isn’t the problem?

Correct — signal strength in the Windows taskbar shows the signal level, not the connection stability. A strong signal can still drop repeatedly due to the power management setting turning the adapter off, the roaming aggressiveness setting forcing unnecessary handoffs, or driver instability. Signal strength rules out physical range as a cause, but the adapter-level settings are the next place to look regardless of the signal bars shown.

Windows 11 disconnects from Wi-Fi whenever I start a video call. Is that a bandwidth issue?

Not usually — video calls consume bandwidth but don’t cause disconnects on their own. This specific pattern (disconnect triggered by video call start) points to the adapter’s power state transitioning under sudden load. When a video call starts, the adapter rapidly increases its transmission rate; if the power management setting is trying to keep the adapter in a low-power state, this sudden demand can cause a brief dropout. Disable the power management setting in Device Manager as described in step 1. If the issue persists specifically during video calls, also update the Wi-Fi driver — some older driver versions have known bugs with handling rapid traffic-level changes.
