“The router keeps disconnecting” can describe several different failures. Your device may lose the Wi-Fi signal, stay connected to Wi-Fi but lose internet access, or only one application may stop working. The fix depends on which layer is actually failing.

Watch the Wi-Fi icon and local connectivity

If the Wi-Fi network disappears or the signal drops, focus on wireless coverage, interference, access-point stability, or the client device. If Wi-Fi remains connected but the internet fails on every device, focus on the WAN/ISP side.

Compare wired and wireless devices

If Ethernet remains stable while Wi-Fi drops, the ISP connection is probably not the cause. Check channel congestion, router placement, firmware, overheating, and band-steering behavior.

Check the physical environment

Keep the router in open air, away from enclosed cabinets and heat sources. Large metal objects, reinforced walls, aquariums, and neighboring access points can reduce signal quality. A mesh node placed at the edge of usable coverage has little good signal to repeat.

Review firmware and power

Use the manufacturer’s supported firmware for the exact model and hardware revision. An unstable power adapter can cause reboots that look like network drops. Check the system uptime/log if the interface provides one.

Test the modem or ONT side

When every device loses internet at the same time, record the modem/ONT indicators and router WAN state before rebooting. That evidence helps distinguish a local router reboot from an ISP signal or authentication problem.

Watch what disappears

If the SSID vanishes or the client drops association, investigate radio/router stability. If Wi-Fi stays connected and the gateway remains reachable but internet stops, investigate WAN/ISP/DNS. If the router itself becomes unreachable, power/firmware/hardware or a reboot loop is possible.

Collect timestamps

Write down when drops occur, whether wired clients fail too, which band/node the client used and what router/modem logs show. Patterns reveal interference, DHCP lease events, WAN renewals or hardware resets better than repeated speed tests.

Mesh-specific checks

A client can appear connected while a satellite loses backhaul. Test near the main node and compare wired backhaul where possible.
