Wi-Fi Connected / No Internet

Networking / Client connectivity / Windows workstation / Rev 1.0
1 / What happened

The device shows Wi-Fi connected, but websites and internet apps do not load.

Symptoms
Wi-Fi connected / browser timeout / Teams disconnected
Applies to
Windows laptop or desktop on wireless network
First rule
Wi-Fi connected does not prove internet access
2 / Why it happens

Most cases are DNS failure, a gateway problem, or the device being on the wrong network path.

3 / Diagnose

Is DNS failing?

  1. Check IP settings.Run ipconfig /all. Record IP address, gateway, and DNS servers.
  2. Ping the gateway.If this fails, treat it as a local network path issue.
  3. Ping an internet IP.If 8.8.8.8 works but websites fail, suspect DNS.
  4. Test name lookup.Run nslookup example.com and record the result.
4 / Fix safely

Restore name resolution

Do not change router-wide DNS settings without approval.
  1. Flush resolver cache: ipconfig /flushdns.
  2. Renew DHCP lease: ipconfig /release, then ipconfig /renew.
  3. Restart browser and retest.
  4. If DNS still fails, escalate with DNS server values.
  5. Verify: websites load by name.
5 / Document it

Record checks, result, fix, and what was not changed.
