How to Fix Wi-Fi Dropping or Disconnecting

Intermittent Wi-Fi drops are more disruptive than slow Wi-Fi — a call that cuts out is worse than a call that runs at 720p. Drops usually have one of four causes: driver issues, router overload, signal interference, or an upstream line problem. Updated 2026-04-27.

Step 1: Identify whether it is Wi-Fi or internet

When the connection drops: can you still reach other devices on your local network (e.g., ping your router at 192.168.1.1)? If yes: your Wi-Fi is up but the internet connection dropped — skip to Step 4. If no: your device lost Wi-Fi connection entirely — continue to Step 2.

Step 2: Update Wi-Fi drivers

On Windows: Device Manager > Network Adapters > right-click your Wi-Fi adapter > Update driver. Outdated Wi-Fi drivers cause intermittent disconnections, especially on Intel Wi-Fi adapters after Windows updates. On macOS: drivers are part of the OS — update macOS. On Android/iOS: check for OS updates.

Step 3: Disable power management on Wi-Fi

Windows aggressively powers down Wi-Fi adapters to save battery — this causes disconnections. Disable it: Device Manager > Network Adapters > right-click Wi-Fi adapter > Properties > Power Management > uncheck 'Allow the computer to turn off this device to save power'. Also check Advanced > Roaming Aggressiveness — set to 'Lowest' to prevent the adapter from dropping a stable router unnecessarily.

Step 4: Check router logs and restart

Log into your router's admin panel and check the system log for disconnect events. Look for WAN-side drops (internet connection lost) vs local Wi-Fi drops. If the log shows repeated WAN drops: the problem is between the router and your ISP — check the modem or contact ISP. If it shows local Wi-Fi drops: the router's Wi-Fi radio is overloaded or overheating.

Step 5: Check for interference and congestion

If drops happen at the same time each day (microwave use, baby monitor, neighbour's heavy Wi-Fi traffic): radio interference is the cause. Switch to 5 GHz or change the 2.4 GHz channel. If your router is in an enclosed cabinet or shelf with no airflow: overheating causes the Wi-Fi radio to drop connections. Move it to an open, ventilated location.

Step 6: Contact ISP for line faults

If your router log shows repeated WAN drops (the internet connection failing, not the Wi-Fi): the problem is the line between your home and the ISP node. Request a line check. A corroded coax connector, failing modem, or node fault can cause intermittent drops that look like Wi-Fi problems from inside the home.

Frequently Asked Questions

Why does my Wi-Fi drop every few hours?

Routers accumulate connection state and sometimes hit memory limits — restarting resolves it temporarily. If drops recur on a schedule: check the router's log for the exact error. Common causes: DHCP lease renewal failures, overheating after sustained load, or ISP PPPoE session timeouts.

Why does Wi-Fi drop when I use the microwave?

Microwave ovens emit radio frequency energy at 2.4 GHz — the same band as 2.4 GHz Wi-Fi. A poorly shielded microwave or a nearby router will experience interference during microwave operation. Fix: switch your device to 5 GHz Wi-Fi, which microwave ovens do not affect.

Can too many devices cause Wi-Fi to drop?

Yes. Consumer routers track each connection in a state table. At 50+ simultaneous connections, older routers run out of resources and start dropping connections. IoT devices (smart bulbs, cameras, thermostats) compound this — each device holds a permanent connection. A router upgrade or disabling idle IoT devices resolves it.
