Chromebook Wi-Fi not working: how to find the cause and fix it

Published Sources checked By helps.wiki editorial team

Chromebook Wi-Fi trouble is usually one of three things: it can't join the network, it joins but has no internet, or it keeps disconnecting. First test another device on the same network. Then restart the router, toggle Wi-Fi, restart the Chromebook and forget and rejoin the network. Powerwash is the last resort.

What it means

"Wi-Fi not working" on a Chromebook covers a few different situations, and the right fix depends on which one you have. Google's troubleshooter separates them: the Wi-Fi link itself fails; the link works but traffic is blocked afterward (a sign-in page, DNS, a proxy, or the router or modem); or other devices connect fine while Chrome devices don't, which points to a managed network that restricts what is allowed on.

The quickest way to tell is to try a phone or another computer on the same network. If that also has no internet, the Chromebook is probably not the problem. The router, modem or internet provider is. If everything else works, go through the steps below in order.

Work and school Chromebooks add another layer, because an administrator can restrict networks and reset options. If yours is managed, some steps may be blocked for you.

Symptoms and causes

You are likely dealing with this problem if:

  • The Wi-Fi network is missing from the list, or joining it fails or times out.
  • The Chromebook shows as connected, but pages won't load or a "no internet" message appears.
  • A sign-in page for a public or school network never appears.
  • The connection drops again and again.
  • The Diagnostics app reports a DNS or connectivity failure.

The usual causes, most common first:

Router, modem or internet provider problem
If a phone or laptop also fails on the same network, the Chromebook is not the cause. ASUS makes the same point in its guide.
Sign-in (captive portal) page not shown or not finished
Public, hotel and school networks often need a sign-in page before they pass traffic. Some Chrome extensions can stop it from appearing.
Stale saved network or wrong password
A saved profile that no longer matches the router can block joining even though the network is visible.
Unsupported network type
ASUS lists the security types and 802.11 a/b/g/n/ac standards Chromebooks support. A network outside that list won't work.
Administrator restrictions
On managed networks, Chrome devices may need their hostnames added to an allowlist, which is why other devices work while the Chromebook does not.
Software fault
A glitch in the system can leave Wi-Fi stuck until a restart or reset.

How to fix it

Work through these in order. They start with the quickest, safest checks and move to deeper repairs; stop as soon as the problem is gone.

1.Test another device and restart the modem and router

Easy

This separates a network problem from a Chromebook problem before you change anything on the laptop.

  1. Connect a phone or another computer to the same Wi-Fi and open a web page.
  2. If that device fails too, restart the modem and router. Switch them off and on again, and let the modem's lights settle before you power the router.
  3. Try the Chromebook again once the router lights are steady.

2.Turn Wi-Fi off and on

Easy

It forces the Chromebook to look for the network again and clears a minor hang.

  1. Open the status area at the bottom right of the screen and turn Wi-Fi off, then on again.
  2. If it does not reconnect, select your network in the Wi-Fi list and connect to it again. ASUS's guide describes the network settings as Settings, then Network, then Wi-Fi; menu names can differ between ChromeOS releases.

3.Restart the Chromebook

Easy

Both Google's troubleshooter and ASUS recommend it, and it clears temporary software faults.

  1. Shut the Chromebook down completely, wait a moment, and turn it back on.
  2. Try connecting again.

4.Forget the network and join it again

Easy

It removes a stale or corrupted saved profile and lets you re-enter the password cleanly.

Before you start: Have the Wi-Fi password ready before you remove the network.

  1. Open the settings for your Wi-Fi network (see the previous steps for the menu path ASUS describes) and select the network.
  2. Remove (forget) the saved network.
  3. Select the network again and enter the password carefully.

5.Run the Diagnostics app

Easy

Google and ASUS both recommend it. It shows whether the failure is at the Wi-Fi link, DNS or further along.

  1. Search for Diagnostics in the launcher, open the app and run the connectivity test.
  2. Note which stage reports a failure (for example DNS) and use the matching step in this list.

6.Get the sign-in page to appear

Easy

On public, hotel or school Wi-Fi, you may be connected but blocked until you finish a sign-in page.

  1. Open a new tab and go to a site that starts with http://, not https://, so the sign-in page can redirect.
  2. If it still doesn't appear, try a private window with CtrlShiftN, if your administrator allows it.
  3. If that fails, turn off your Chrome extensions and try again.
  4. If you signed in but still have no internet, disconnect and reconnect. You can also check the sign-in works from a phone.

7.If the connection keeps dropping

Easy

The sources used for this article give no dropout-specific fix, so this is only a way to narrow down where the problem lies.

  1. Connect the Chromebook to a different network, such as a phone hotspot, and see whether it stays connected. If it does, the fault is likely with your router or its network, not the Chromebook.
  2. If it drops on every network, work through the restart and forget-and-rejoin steps above, then the Powerwash step if nothing helps.

8.Managed networks where other devices work

Moderate

If phones connect but Chrome devices don't, the network may be filtering by device type.

  1. Contact the network administrator and ask them to add the Chrome hostnames to the network allowlist, as described in Google's troubleshooter.

9.Powerwash the Chromebook (last resort)

AdvancedBack up first

It resets the Chromebook to factory settings and clears software problems that nothing else fixed.

Before you start: Powerwash erases local data. Back up your files first, for example to Google Drive. Work and school devices can't be reset by the user, so contact your administrator instead.

  1. Back up your local files.
  2. Sign out of the Chromebook.
  3. Press and hold CtrlAltShiftR, then select Restart.
  4. In the prompt, choose Powerwash, then Continue.
  5. Sign in with your Google Account, which becomes the device owner.

Check that it worked

  • The Chromebook shows as connected and a web page loads normally.
  • The Diagnostics app no longer reports a connectivity failure.
  • The connection stays up for several minutes without dropping.

If it still fails

  • If even Powerwash did not help, and other devices work on the same network, a hardware fault in the Chromebook is possible. Contact the manufacturer for support.
  • Forum reports show cases where nothing on the Chromebook helped and the cause was the router, so test the Chromebook on a different network, such as a phone hotspot, to narrow it down.
  • You can also ask on the Chromebook Community Forum.
  • On a school or work device, ask your administrator to check network and device policies.
