Kindle whispernet connection

it's possible to fix kindle connection problems to whispernet following the amazon customer service directives:

Visit your Kindle's Settings screen by selecting that option from the Home screen menu. When you're on the Settings screen, type 311 on Kindle's keyboard.

When prompted to switch wireless providers, select "OK" to see a list of providers in your area. Please allow up to two minutes for Kindle to complete a search of available wireless providers.

Select a carrier from the list and wait for Kindle to return to the Setting screen and attempt to connect to Whispernet. If after two minutes you are still unable to connect or your signal strength does not improve, please repeat the steps above and select a different carrier from the list.

I copied drools documentation on my kindle in this way:

import the saved page in the calibre's ebook library, fix metadata and convert to mobi

move the ebook in the kindle
