Why your internet is down on all devices

This page is for the moment when every laptop, phone, TV, or smart-home device seems offline at the same time. The goal is to separate provider trouble, modem or router trouble, and local Wi-Fi assumptions before the whole setup gets reset without a plan.

Pillar: Home & Office Networking Type: Guide / troubleshooting hybrid Whole-network outage diagnosis

A whole-network outage is different from weak Wi-Fi

If everything is offline at once, start with the internet edge before you focus on room-by-room coverage.

Scope matters first

Wired devices, wireless devices, and gateway reachability tell you whether the trouble is local or upstream.

Restart order only helps after the symptom is clear

Resetting everything too early makes it harder to tell whether the provider, modem, router, or WAN path failed first.

Keep the outage check focused

  • Confirm whether both wired and wireless devices are down or whether the issue is actually narrower.
  • Look at modem, router, or gateway status before assuming the Wi-Fi layer is the whole problem.
  • Check whether any device can still reach the local network or gateway even when the internet edge is down.
  • Notice whether the outage followed a power event, ISP maintenance, cable change, or equipment restart.

Open the page that matches the failure surface

Start with modem and router basics if the device roles are still fuzzy. Start with outage recovery if power loss or a desk-wide interruption came first.

Use the closest live repair branch

Use the gear pages only after the outage shape is clearer

This page should still lead with scope, gateway checks, and outage timing before new hardware. When the evidence points to cabling, power protection, or Wi-Fi equipment, use the reusable bundle pages instead of guessing at individual products inside every article.
