Wi-Fi & routers

Wi-Fi works on phone but not on laptop

When only a laptop can't get online while phones work fine, the problem is usually on the laptop's network settings, adapter drivers, or a saved network profile rather than the router or internet connection.

Symptoms

  • Laptop shows connected to Wi-Fi but no internet access
  • Laptop can't see the network at all while phones can
  • Laptop worked on this network before and suddenly stopped
  • Problem follows the laptop to other networks too, or only happens at home

Likely causes

  • CommonLaptop's saved network profile is corruptedWindows and Mac both store network-specific settings that can get out of sync with the router.
  • CommonOutdated or buggy Wi-Fi adapter driverWi-Fi driver issues are a very common cause of connectivity problems specific to one computer.
  • PossibleIncorrect IP or DNS configuration on the laptopManually set network settings on a laptop can conflict with what the router expects.
  • PossibleVPN, antivirus, or firewall software blocking network accessSecurity software occasionally blocks Wi-Fi traffic even when connected.
  • Less commonLaptop's Wi-Fi adapter hardware issueAn aging or damaged Wi-Fi card can cause intermittent or complete connectivity failure.

What to do

  1. On the laptop, forget/remove the saved Wi-Fi network and reconnect fresh with the password.
  2. Restart the laptop, since this clears many temporary network glitches.
  3. Check Device Manager (Windows) or System Report (Mac) for the Wi-Fi adapter and update its driver, or reinstall it if an error is shown.
  4. Make sure the laptop's network settings (IP, DNS) are set to obtain automatically rather than a manual/static configuration, unless intentionally configured otherwise.
  5. Temporarily disable any VPN, antivirus, or firewall software to see if one of them is blocking the connection.
  6. Run the built-in network troubleshooter (Windows: Settings > Network > Troubleshoot; Mac: Wi-Fi diagnostics) for automated fixes.
  7. If the laptop fails to connect on multiple different networks, not just yours, its Wi-Fi hardware likely needs professional diagnosis.

Tools and parts

When to call a pro

If driver updates and a factory network reset don't resolve it, a computer repair shop can test the Wi-Fi adapter hardware directly.
