Wi-Fi Router diagnostics

Test what the browser can see. Know when it cannot.

Use endpoint connectivity evidence to separate a single-device browser problem from a wider Wi-Fi/router outage before resetting or replacing network equipment.

Run these first

Relevant live checks

Browser Online Status TestCheck the browser online state, available connection hints, and a short round trip to DeviceOK.
→
Browser Latency TestMeasure several browser-to-DeviceOK request round trips as a quick connection responsiveness check.
→
Network Information CheckRead browser-exposed connection type, estimated round-trip time, downlink, Save-Data state, and online status where supported.

First diagnostic sequence

Do the high-signal checks before risky changes

  1. 1

    Compare another device on the same network

  2. 2

    Compare Wi-Fi and Ethernet/mobile data if available

  3. 3

    Restart/reset only after identifying whether the issue is local or network-wide

What DeviceOK/browser can help check
  • Confirm browser reachability through the current network path
  • Measure DeviceOK application-level round trips
  • Show coarse connection hints where exposed
What this browser page cannot prove
  • Log into or reconfigure arbitrary routers automatically
  • Scan Wi-Fi RF channels universally
  • Prove WAN/modem line quality
