Hi Freddie.

It seems it is not connected to a Wifi Network,

DO you have a working Wifi NEtwork available?

Ok, first Can you share a phone number in case we got disconnected?

Also I need to know if you know what is your wifi name and wifi password?

I see,

Ok First I need you to check on your kindle.

Go to the Settings and go to where it says Wifi or wireless, check there if you see your wifi name and if it says connected?

If not try connecting it to the Wifi and and let me knowhow it turned out.

I'll wait for your response.

Thank Freddie,

Where do you see the orange light?

Also Can you try restarting both the Kindle and Wifi?

This should reset if there is any conflict between the 2 this is the most common.

You can restart the Kindle BY

Hold down the power button on the kindle Until it ask you about powering OFF, Then proceed to power OFF

Once Its OFF Hold the power button down until you see the Kindle logo and it should turn it self ON.

You can restart the Wifi BY

UNplugging the router's power and plugging it back in.

Once you did both go back to settings and check the status of the connection again and try reconnecting the kindle to the Wifi.

Let me know how it works.

Try repeating the steps I gave you. try to be as close to where the router is at.

Restart the router box again

and try reconnecting.

1. Swipe down from the top of the screen to show Quick Settings, and then tap Wireless.
2. Verify that Airplane Mode is Off.
3. Next to Wi-Fi, tap On.
4. Tap a network to connect to it. If you see a lock icon, a network password is required. Enter the Wi-Fi network password, and then tap Connect.

    

Please Let me know if it did work or made any changes.

When you check the Kindle's settings / Wifi /wireless

Does it say your wireless name? This will let us see if you failed to connect to the router or you're connected but not getting wifi data.

Wireless Name is the name broadcasted by your wireless router.

in your wifi settings you should be able to see if you are connected to the router or not

Example:

Kindle connected to "Charlie's-pc" wireless name

Does it says you're connected to it?

when you try connecting to it what does it say?

If it does say connected,

Can you try opening maybe an internet browser on your Kindle or other feature that uses internet and see if that responds?

Any Update Freddie?

Were you able to open Internet browser on your kindle if it work?

The Kindle HD7 should have an app called "SILK" 

This works like internet explorer or Web browser for the Kindle
