Home router keeps disconnecting devices

Where this problem appears

Home routers and mesh systems serving phones, computers, TVs and smart-home devices.

Symptoms to confirm

• Several devices lose connection at the same time.
• Wi-Fi remains visible but internet access stops.
• Only distant rooms or one frequency band are affected.

Likely causes

• The modem or ISP connection is dropping.
• The router is overheating or rebooting.
• Wireless channels are congested.
• Band steering, mesh backhaul or old client drivers are unstable.

Work in order

Step-by-step fix

1. 1

   Note whether the router's internet light changes when the outage occurs.

2. 2

   Test one computer over Ethernet to separate internet failure from Wi-Fi failure.

3. 3

   Restart the modem and router once, then wait for a complete reconnection.

4. 4

   Move the router into open air away from heat, metal cabinets and other transmitters.

5. 5

   Install current firmware from the router manufacturer and back up settings first.

6. 6

   Test separate 2.4 GHz and 5 GHz network names temporarily to identify a band-specific problem.

7. 7

   If Ethernet also drops, record times and modem signal information before contacting the ISP.

If the main path does not work

• Change only the busy Wi-Fi channel rather than resetting every setting.
• Update the wireless driver on one affected computer and compare it with other devices.

How to reduce repeat failures

Keep firmware current, provide ventilation and document working channel and mesh settings before changes.
