Sometimes we get notifications from students about their Chrombook not connecting to the internet while at home.  They join the home network which is working for all the other computers and tablets at home, but it isn't working for their Chromebook.
I'm going to try and provide some basic troubleshooting tips for the screen capture shown below.
SSL Error Message

First I'd like to point out a few things.
The Chromebook has connected successfully to a local wireless network:

Cool!  How come I see web page is not available?

A quick review of the page and a 2 things that jump out.  In the lower left hand corner it says "Waiting for proxy tunnel..."

Then at the top I notice that the page that is open is trying to reach the SSL site

From a simple Google search I get the following info about SSL
SSL (Secure Sockets Layer) is a protocol that provides secure communications on the Internet for such things as web browsing, e-mail, instant messaging, and other data transfers.

As part of our 1:1 pilot with the Chromebooks we have been asked to provide web filtering at home.  We accomplish this via our web filter back at the district office.  In order for this to work, we push an SSL certificate out to each Chromebook.  Therefore students attempting to go to SSL sites like need to authenticate to our filter before attempting to access that site.

Power the Chromebook completely off.  Hold down the power button for 10 seconds until the Chrombook shuts completely off.
The button is directly above the backspace key on the upper right hand corner of the keyboard.

When you power the Chromebook back on, you will need to login like normal.  
Now when you open up a web page you should be greeted with everybody's favorite web filter authentication page.

If you do not see the filter authentication page shown above, you may need to attempt to go to a non-SSL web site.  Such as This should generate traffic though the filter that will bring up the filter authentication page.  Once you authenticate to the filter, your SSL pages should load correctly.
