Chromebook won't connect to Wi-Fi

Symptoms

• Wi-Fi icon shows no connection or an exclamation mark
• Connects but no internet access
• Keeps disconnecting repeatedly
• Other devices connect to the same network fine

Likely causes

• CommonSaved network settings are outdatedA changed router password or settings can leave an old saved profile broken.
• CommonRouter or modem issueIf other devices also can't connect, the problem is likely the router, not the Chromebook.
• CommonWi-Fi turned off or in airplane modeAn accidental toggle disables the radio entirely.
• PossibleOutdated ChromeOS network drivers/firmwareA pending system update can include Wi-Fi fixes.
• Less commonMAC address filtering or captive portal issueSome networks block unregistered devices or require a login page that didn't load.

What to do

1. Check the status bar to confirm Wi-Fi is on and not in airplane mode.
2. Click the network icon, select the network, and choose Forget, then reconnect and re-enter the password.
3. Restart the Chromebook and separately power-cycle the router by unplugging it for 30 seconds.
4. Try connecting to a different Wi-Fi network (like a phone hotspot) to see if the problem follows the Chromebook.
5. Go to Settings > About ChromeOS and check for a pending update, then install it and restart.
6. If only this network fails on multiple devices, log into the router and check for MAC filtering or band settings (2.4GHz vs 5GHz).

When to call a pro

If no device can connect and a router restart doesn't help, contact your internet provider.
