Troubleshooting

Why Does My WiFi Keep Disconnecting? (Fixes)

Updated 2026 · 8 min read

WiFi that keeps dropping is maddening — and usually fixable. Work through these causes in order, from most to least common.

1. Router overload or overheating

Routers that run hot or stay on for months drop connections. Reboot it, ensure it's ventilated, and replace very old hardware.

2. WiFi interference

Microwaves, cordless phones, baby monitors and neighbours' networks disrupt 2.4GHz. Switch devices to 5GHz and change your channel to 1, 6 or 11.

3. Weak signal / range

If drops happen far from the router, it's a coverage problem. Move closer, reposition the router centrally, or add a mesh node.

4. Outdated firmware or drivers

Update the router firmware and your device's WiFi driver — both fix stability bugs.

5. Too many devices

Cheap routers choke when many devices connect. Remove unused ones or upgrade to a router rated for more clients.

6. Power management

On laptops, Windows may turn off the WiFi adapter to save power. Disable that in adapter settings.

7. ISP / line issues

If the modem (not just WiFi) drops, check cables and run a test for packet loss. Persistent loss means a line fault — contact your ISP.

Key takeaway: Most WiFi drops come from interference, overheating routers, or weak signal. Reboot, switch to 5GHz, update firmware, and check coverage before blaming your ISP.
