Network issues are bad, but they're worse with a Chromebook. Chromebooks thrive on an active Internet connection, even though apps are being developed for offline use. When that connection is severed, the Chromebook can be like a fish out of water.
While there are ways to get work done while offline on a Chromebook, chances are you'll need your connection back as fast as possible. With a few simple steps, you can get your Chromebook back online where it belongs.
Where the wireless settings are
There are two places where you can make changes to your wireless settings on a Chromebook. The most convenient route is through the status area in the bottom right-hand corner of your Chromebook's shelf.
Click anywhere in the status area to expand it: Among other basic settings, it'll show your current connection in the Network bar near the top. If you're connected to a network, it should say, "Connected to [Network Name]."
If it says "No Network," click the box to open up a list of available Wi-Fi Networks. You can click Join other... or Settings at the bottom to enter a network manually.
Click the Settings bar at the bottom of the expanded status area to launch into the full Settings page within the Chrome browser, which delves deeper into your Chromebook's settings. In the Internet Connection section at the top, you can allow proxies for shared networks and edit your saved wireless connections.
Make sure your Chromebook is connected to Wi-Fi
If the password for the network you're trying to connect to has changed, you'll need to re-configure the connection to update the password. From the list of available networks in the Settings tab in Chrome, click the network name you want to connect to.
Click the Configure button at the bottom of the pop-up window to enter the new password and click Connect.
Run Google's diagnostic tool
If you're actually connected to a network but are having issues with your connection, you'll want to run Google's Chrome Connectivity Diagnostics App built specifically for Chromebooks.
The app runs a detailed diagnostic that gives you in-depth information on what could be causing you trouble. It makes sure Chrome is up-to-date, checks for a DNS server, and it also checks whether internet traffic is being blocked by a captive portal.
Reboot all the things!
If you've tried everything listed above, your laptop likely isn't the problem. When in doubt, follow the age-old advice of turning everything off and on again.
Turn your Chromebook off, turn the modem off, and turn off the router if you have a separate one. Wait a good minute or two, then begin rebooting your devices. Start with the modem, followed by the router and then, finally, your Chromebook. If that doesn't fix your problem, move on to the next step.
