Wi‑Fi keeps disconnecting: router troubleshooting checklist

Random Wi‑Fi drops are frustrating, but most causes are predictable.

1) Reboot modem + router (in the right order)

1. Unplug modem and router
2. Plug in modem, wait 2–3 minutes
3. Plug in router

2) Update router firmware

Old firmware can cause stability issues.

3) Check for overheating

Make sure the router has airflow and isn’t buried behind a TV.

4) Switch bands / channels

• 5GHz: faster, shorter range
• 2.4GHz: longer range, more interference

5) If the router is old, replace it

If it’s not Wi‑Fi (it’s the ISP)

If wired connections also drop, it’s often the modem/ISP line.
