Family 1 to 1 Tech Tips and Tricks

We are going to use this page to provide information that we believe help parents and students utilize the 1:1 technology we are providing for home use.  As we hear of common issues and questions we will do our best to post responses here.  If you have a topic you'd like help with, or have tech questions, please email  
Sometimes we will gather general help information that other districts have shared with their families.  When we do, we will include a link to the original post.

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.

Connecting to an Open Network

Some restaurants and public places (ex. DeKalb Public Library, NIU) offer open networks that our chromebooks can connect to.  
A common issue we see is that when someone opens up their chromebook and connects to the network the splash screen doesn't always show up.  While at the DeKalb Public Library today we found that to be the case.  We simply shut down the chrombook by holding down the power button for 5 seconds.  Then turned the chromebook back on.  This time when we joined the library wireless we were greeted with the following splash screen:
Note: Sorry for the photo quality, but we couldn't use Snagit for a screen capture at the time and had to take a photo of the screen using a cell phone.
Simply click the accept button, log into your chromebook, and access your Google Apps via the internet.

Frontier Network Settings

Now that things appear to be working correctly with the Chromebooks and our webfilter (, we've been able to work with Frontier on the various setting options.  In our initial conversations with Frontier, they simply stated that our families should leave their DSL firewall to no security as that is the default setting.  While that worked for testing purposes, it isn't something we would ever recommend.  We don't agree with that and have been testing some of the other options.
Once you are able to log into your modem, please select Firewall from the top menu.  You should then see a page that looks similar to this:
We found that No Security and Medium Security worked without any special configuration.  You may be comfortable with selecting one of those options.  Overall we would recommend that you choose "Typical Security" as shown in the photo above.  However, once you select Typical Security and click apply, the district provided Chromebook will no longer work correctly as it won't be able to communicate with our web filter at

There are a couple of extra steps that you'll need to complete to allow the Chromebook to communicate with our filter correctly.

Your going to want to create a Dynamic Trigger Port called 428Filter for port 8888.
Click Port Forwarding that is in the left hand menu.
You'll get a warning message, but if you want to proceed, you'll need to click the Yes button.
Leave your current profile alone and click the Add link near the bottom.
Click the Create button on the New Port Forwarding Rule.

On the next page first select the radio button for "Port Triggering".
After the page refreshes, fill it out so that it looks like the screen shot below and click apply.

You will be taken back to the New Port Forwarding Rule page.
Select your newly created rule from the drop down menu.
Select Dynamic.
Click Apply.
You might get a message that the rule is already active.  If that is the case, just click cancel.

Click close one more time and you should be all set.
