Optional - Connect to a public network: Enter any required information if you are connecting to a public network that requires a web browser to sign in, like a school or hotel. The information could be a pre-shared password, room number, or just a button to accept conditions for using the network. This information cannot be saved to Amazon. Contact the network owner for more information.

Select Connect. After your device connects to your Wi-Fi network, a confirmation message appears in the app. You're now ready to use Alexa.

How many 'bars' are showing on wi-fi signal strength indicator (presuming you are using wi-fi for internet access)? If the signal strength is low, you could be losing connections that way, or there might be interference on the wi-fi channel that the tablet is using. Try changing channels in your wi-fi setup and see if there is an improvement in the behavior.

Try this first....on the tablet go to settings and wifi.let it scan for your known router.once found do not try to connect but look for the arrow on right to try and set dchp etc.you should see a message somewhere on the page " Forget this network" click on it , rescan wifi again.this time your router will ask for the password.re input before timeout and it should be good to go.

It's a good idea to access Wi-Fi whenever possible to avoid data charges. After you've activated the Android tablet's Wi-Fi radio, you can connect to an available wireless network. Obey these steps:

1. Open the Settings app.
2. Choose Wi-Fi.On some Samsung tablets, you find the Wi-Fi item on the Connections tab. Choose Wi-Fi to view a list of available Wi-Fi networks on the right side of the screen. Otherwise, the list shows up full screen.
   
3. Choose a wireless network from the list.When no wireless networks are listed, you're sort of out of luck regarding Wi-Fi access from your current location.
4. If prompted, type the network password.
   Touch the Show Password check box so that you can see what you're typing; some of those network passwords can be long.
5. Touch the Connect button.
   The network is connected immediately. If not, try the password again.

When the tablet is connected to a wireless network, you see the Wi-Fi Connected status icon. This icon indicates that the tablet's Wi-Fi is on, connected, and communicating with a Wi-Fi network.
Some wireless networks don't broadcast their names, which adds security but also makes connecting more difficult. In those cases, touch the Add icon. This icon might also be labeled Add Wi-Fi or Manually Connect. To make the connection, type the network name, or SSID, and choose the type of security.
You also need the password, if one is used. You can obtain this information from the girl with the pink hair who sold you coffee or from whoever is in charge of the wireless network at your location.

• Not every wireless network has a password. Still:
• Be careful when connecting to a non-password-protected network. It's possible that the Bad Guys can monitor such a network, stealing passwords and other information.
• Some public networks are open to anyone, but you have to use the web browser app to find a login web page that lets you access the network: Simply browse to any page on the Internet, and the login web page shows up.
• The Android tablet automatically remembers every Wi-Fi network it has ever been connected to and automatically reconnects upon finding the same network again.
• To disconnect from a Wi-Fi network, simply turn off Wi-Fi.
• Use Wi-Fi whenever you plan to remain in one location for a while. Unlike a mobile data network, a Wi-Fi network's broadcast signal has a limited range. If you wander too far away, your tablet loses the signal and is disconnected.

Solution 1.Check wireless connection.
The first step of diagnosis have to any other device connected to the same network, ensure the wireless connection is working fine, or verify the settings of your wireless router to correct it.
2.Check your Keep Wi-Fi on during sleep Settings.
Owing to Wi-Fi sleep policy your Wi-Fi connection may be going to get disconnected every now and then.
Tweak this policy to keep your Wi-Fi connection awake.
[Settings] >>[Wi-Fi]>>[Advanced]>> Check [Always] to keep the Wi-Fi on during sleep.
Save changes and exit all the screens. Your Wi-Fi will never get disconnected again due to this policy.

3.Check signal strength of wireless connection.
The performance of a wireless network connection depends in part on signal strength.
You have to connect the Wireless network where the signal strength is strong.
Check Wireless network signal strength icons in notification bar.

4.Try to turn off/on Wi-Fi on the device.
First to turn off Wi-Fi, [Settings]>>[Wi-Fi] >>[turn Wi-Fi to off].
And then to turn on Wi-Fi, [Settings]>>[Wi-Fi]>>[turn Wi-Fi to on].

5.Try to forget network on the device.
Forgetting wireless networks allow your tablet/phone to reset some settings.
[Settings]>>[Wi-Fi]>>Press & hold your[Net Work Name(SSID)]for 2 seconds.
>>Select[Forget Network]>>Re-Connect your wireless networks if it's disconnected.

6.Try to reboot your device.
7.Make sure your firmware is up-to-date.
>>Select[Settings]>>[About tablet]>>[System Firmware Update]>>[Check Update].

8.Try to reset your device.

Third-party programs might be the major probability of Tablet/Phone instable, suggested to have a full reset for the device if the situation persists.
[Settings]>>[Backup&reset]>>[Factory data reset]

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.
  

If you do not have internet connection with wireless LAN at home, you need to set up your Kindle to use the 3G service. This is the default setting when the device is delivered to you, and I believe it worked until you or somebody else inadvertently changed the configuration.
Follow this step-by-step procedure:

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.
