Why does my laptop Wi-Fi keep disconnecting?

Common causes are outdated Wi-Fi drivers, adapter power saving, poor roaming between access points, interference on 2.4 GHz, or a corrupt Wi-Fi profile. If only your laptop drops, start with drivers and power settings.

Why does my phone stay connected when my laptop drops?

Phones and laptops use different chips, drivers and roaming logic. A phone staying connected suggests the laptop driver, power management or settings, not the network.

How do I see when Wi-Fi dropped?

Run netsh wlan show wlanreport in an elevated command prompt on Windows. It creates a report of connection sessions, disconnects and reasons.

Will a different router fix office Wi-Fi drops?

Only if the access point is the cause. Check whether many devices drop in the same area first. A single laptop with an old driver will not be fixed by new network hardware.

Wi-Fi keeps dropping on a work laptop

Laptop Wi-Fi disconnects every few minutes while phones stay connected? Drivers, power saving, roaming, band steering and access point checks.

Teams calls freeze, the VPN reconnects, and the Wi-Fi icon flickers every ten minutes. The user's phone, on the same network, never notices. Intermittent Wi-Fi drops are harder than a dead connection because by the time IT looks, it is working again. The trick is to capture evidence and test one change at a time. This is different from connected but no internet, where the link stays up but nothing passes.

Who is affected?

One laptop. Driver, power management, a corrupt Wi-Fi profile, or hardware. Stay on the device.
One model. Several laptops of the same make drop together after an update — driver or firmware regression.
Everyone in one area. Access point, channel interference, or coverage gap.
Everyone everywhere. Wireless controller, DHCP, RADIUS or the internet circuit. Check whether SaaS services like Microsoft 365 or Zoom are actually having trouble before blaming Wi-Fi — but most often they are not.

User checks

Forget the network and rejoin. Corrupt profiles and old saved passwords cause repeated drops after password rotations.
Move closer to the access point for a day as a test. If drops stop, it is coverage or roaming, not the laptop.
Turn off Bluetooth briefly. Some combined Wi-Fi/Bluetooth chips struggle on 2.4 GHz with headsets connected. If drops stop, update drivers rather than leaving Bluetooth off.
Docking stations. A dock with Ethernet can cause Windows to switch adapters. Test undocked, or plug in Ethernet at the desk and stop fighting Wi-Fi.
Check for VPN reconnects. Sometimes the VPN drops, not the Wi-Fi. The Wi-Fi icon tells you which: if the Wi-Fi stays connected while the VPN reconnects, read VPN connected but no internet.

Device fixes (IT)

Update the Wi-Fi driver from the laptop manufacturer or chipset vendor, not just Windows Update. Intel, Realtek, Qualcomm and MediaTek drivers fix roaming and stability bugs regularly. Also update BIOS/firmware.
Power management. Device Manager → network adapter → Power Management → untick Allow the computer to turn off this device to save power. In the adapter's Advanced tab, look for power-saving or MIMO power save settings. Check the Windows power plan too.
Roaming aggressiveness. In the adapter's Advanced tab, tune roaming aggressiveness. Too high and the laptop hops between access points; too low and it clings to a weak one.
Preferred band. Setting the adapter to prefer 5 GHz (or 6 GHz on Wi-Fi 6E) avoids crowded 2.4 GHz channels.
Network reset. Settings → Network & internet → Advanced network settings → Network reset reinstalls adapters. It also removes VPN adapters, so be ready to reinstall the VPN client.
Collect evidence. netsh wlan show wlanreport generates an HTML report of disconnects and reasons over the past days. It turns "it drops sometimes" into timestamps and reason codes.

Network fixes (admin)

Channel planning and interference. Neighbouring offices, microwaves, and too many access points on the same channel cause drops. Use the controller's RF view or a survey app.
Band steering and minimum RSSI. Aggressive settings kick clients off before they find another access point. Some older laptops handle 802.11k/v/r roaming badly; test with fast roaming disabled on a test SSID.
802.1X / RADIUS. Certificate-based Wi-Fi drops when certificates expire or RADIUS servers time out. Check NPS or the RADIUS logs for rejected re-authentications.
DHCP lease and pool. Short leases with an exhausted pool cause disconnects at renewal.
Access point firmware and overload. One consumer-grade access point in a 30-person room will drop clients during every all-hands. Add capacity rather than blaming laptops.

When to escalate

Escalate to the network team or wireless vendor when many devices drop in the same area or at the same times, with the WLAN report to prove it. Escalate to the laptop vendor when one model drops after a driver or firmware update. Escalate to the ISP only if wired clients drop too.
