Wi-Fi Adapter diagnostics

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

Use browser connectivity evidence plus OS adapter state to separate a web/app problem from a Wi-Fi adapter or network problem.

Run these first

Relevant live checks

First diagnostic sequence

Do the high-signal checks before risky changes

  1. 1

    Compare another device on the same Wi-Fi

  2. 2

    Compare Ethernet or another network if available

  3. 3

    Inspect adapter state/driver only after broader network checks

What DeviceOK/browser can help check
  • Test HTTP connectivity
  • Show coarse connection hints where exposed
What this browser page cannot prove
  • Read Wi-Fi RSSI/channel on every browser
  • Scan radio spectrum
  • Replace router/adapter diagnostics
