I received a message that someone tried to log into my gmail account, and it told me to change my password, so I did. Now when I try to get into my messages on my kindle fire I receive a message that authentication failed. I have tried everything google has told me to do, but still can't fix the problem, what should I do, or who should I contact?

You are mixing up two things: 3G and Wi-Fi.

3G is a mobile phone data service, supported by selected Kindle devices. Your Kindle 3 3G has a SIM card built inside, just like the fingernail-size chips you put into a mobile phone. Amazon set up contracts with phone service providers in many countries so you can use it to download books to your Kindle at no extra costs for you other than the higher price of Kindle 3 3G compared to the non-3G version. You do not need any extra hardware for this to work, and it will work in most places of the world. This is the guarantee you were promised.

Wi-Fi is a wireless communication standard all Kindle devices support. While most hotels, airports and some restaurants provide free Wi-Fi access for guests, you need your own WLAN router at your home, and pay for your own broadband internet service. The "all sorts of wireless connections which are all password protected" belong to your neighbors and they are password protected so that nobody can take a free ride on the service they pay for.

You can tell the connection status of your Kindle from symbols in in the status bar, at the top right of the screen:

• If it shows "OFF", wireless connectivity is deactivated and you cannot access the internet from your Kindle, or download books.
• If it shows "Wi-Fi", the Kindle is connected to a Wi-Fi network. The five bars right of the symbol represent the connection's signal strength, the more bars are black, the better.
• If it shows "3G", you are connected via 3G mobile data service. The bars right of this symbol refer to mobile phone service signal strength, much like a mobile phone would show you.
  

1. Switch on your Kindle.
2. Press the "Home" button.
3. Check the status bar. Does it show the "3G" symbol? If yes, how about signal strength? If you are somehow blocked from mobile phone antennas in your area, signal strength will be low and the Kindle will not have internet access. Move around and see if it becomes better.
4. Does it show the "OFF" symbol? If yes, press the "Menu" button. A menu of commands should open. Use the four-way button just below "Menu" to underline the top-most option "Turn Wireless On" and press the center of the four-way. The menu list will close, and after a moment Kindle will try to connect to the internet.
5. Does it show the "Wi-Fi" symbol? If yes, I assume you accidentally connected to a neighbor's Wi-Fi network and its firewall protected, or is too far away to use it. In this case, press the "Menu" button to open the command menu. Use the four-way button just below "Menu" to underline "Settings", second option from the bottom, and press the center of of the four-way. The settings menu will open. Use the four-way button to navigate down to "Wi-Fi Settings" (the text "view" must be underlined) and press the center of the four-way. The list of Wi-Fi networks open. Navigate down using the four-way to any network with the text "forget" on it and press the center of the four-way.

Four reasons come to mind that may prevent you from connecting:

1. Wi-Fi Passwords are case sensitive. Please check again if you entered the password with proper casing and you did not put any extra white space in front or behind. I know, this sounds annoying, but it is really the most common cause for connection problems.
2. Give your network a unique SSID. This is the network name that shows up in the list of detected networks. Default names like LINKSYS can be troublesome if a neighbor one block down the street happens to have a router from the same company.
3. Some routers have a MAC address filter as a security measure, limiting service to devices specifically whitelisted. If your router is set up for this, add your Kindle's MAC address to the list of permitted devices. See your router's configuration under Wireless > Wireless MAC Filter. You can check the MAC of your Kindle from its settings page (press HOME, MENU, select SETTINGS, see paragraph headlined "Device Info".
   
4. There are twelve different standards for Wi-Fi transmission collected under the hood IEEE 802.11. The four most dominant transmission modes are called a, b, g and n. They differ in radio frequency, modulation method and data rate. Kindle supports the two standards IEEE 802.11 b and g only, which is not really a problem because all wireless routers I ever encountered support one or both of these, too. However, the Linksys N-series can be set up to use 802.11n exclusively, not allowing for b or g connections. In the router menu Wireless > Basic Wireless Settings (Manual Setup), make sure the network mode is configured as "Mixed".

How to download books to your Kindle from your computer

We had a reader email us and ask us how he could get a TeleRead-mentioned e-book onto his Kindle. In case anyone else would like a tutorial, here's how to do it.

Download the e-book to your computer. Connect the Kindle to the computer's USB port. The Kindle will show up as a new drive on your computer. If you have an SD card in the Kindle it will show up as a second new drive. Copy, or drag and drop, the e-book to the Documents directory in the Kindle or SD card. That's all there is to it. When you disconnect the Kindle the machine will automatically recognize the new book. Be sure not to disconnect the Kindle until the little silver block at the bottom right stops spinning around.

If you use an SD card, you can dispense with all of the above and just remove the SD card from your Kindle and connect it to a card reader and copy the book directly from your PC to the proper directory on the card. The Kindle will recognize the new book when you plug the card back in. To be safe, shut off the Kindle when removing or inserting the card.

You can also just email it to your kindle's address. Although there is mention of a 10 cent charge per email, no one has ever been charged and Kindle support says there are no plans to do so, at this time.

It's definitely being charged now - I sent a 50 MB PDF to my kindle email address and received a $4 charge.

SOURCE: What do I do to my lap top or kindle to receive emails

There is no specific email client on the Kindle so you can only receive your emails via the experimental web browser and using a web mail service to access your mail.

SOURCE: How do I set up my computer to receive my emails on my kindle?

The only way is to use the experimental browser- at the home screen, press "Menu". Then press "Experimental", followed by "Browser". Then, type your email client. However- email (and the whole browser, really) is sluggish and slow on the Kindle. It is much easier to just check it on a computer, or any other wireless device.
