How to reset wireless network adaptor

Wi-Fi provides wireless Internet access over distances of up to 100 meters (00 feet).

To use Wi-Fi on your phone, you need access to a wireless access point or "hotspot". The availability
and range of the Wi-Fi signal depends on the number, infrastructure, and other objects
through which the signal passes.

Turning Wi-Fi on and connecting to a wireless network
From the Home screen, press MENU, and then tap Settings > Wireless & networks.
Select the Wi-Fi check box to turn Wi-Fi on. The phone then scans for available wireless
networks.

Tap Wi-Fi settings. The network names and security settings of detected Wi-Fi networks
are displayed in the Wi-Fi networks section.
If the wireless network you want to connect to is not in the list of detected networks,
scroll down the screen, and then tap Add Wi-Fi network. Enter the wireless network
settings, and then tap Save.

Tap the Wi-Fi network you want to connect to.
If you selected an open network, you will be automatically connected to the network.
If you selected a network that is secured with WEP, enter the key and then tap
Connect.

Depending on the network type and its security settings, you may also need to enter more information
or choose a security certificate.
When your phone is connected to a wireless network, the Wi-Fi icon appears in the
status bar and tells you the approximate signal strength (number of bands that light up).
The next time your phone connects to a previously accessed secured wireless network, you
will not be prompted to enter the key or other security information again, unless you reset
your phone to its factory default settings.

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.

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.

>>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.

You must have internet service, example an anything data plan. Then all you do is tap on the internet ball and it conects.

Resolution If you know there is a nearby Wi-Fi network, but you are unable to locate it on the Settings > Wi-Fi screen:

• Move closer to the Wi-Fi router or hotspot.
• If you are using a personal Wi-Fi network, verify the Wi-Fi router is connected to power and turned on.
• Wi-Fi networks configured as "closed" or "private" do not broadcast the network name to Wi-Fi devices.
  • Join a "closed" or "private" network by tapping Settings > Wi-Fi > Other and entering the Wi-Fi network name, security, and password.

After joining a Wi-Fi network, if you notice the signal strength is low or intermittent

• Move closer to the Wi-Fi router or hotspot.
• Check for any sources of potential interference.
• Remove any cases or attachments on your device that could interfere with a Wi-Fi signal.

If you are unable to access the Internet while connected

• If you are using a commercial Wi-Fi network that requires a special login or subscription, see this article for more information.
• If you are in a location with multiple Wi-Fi networks, verify that you are selecting the correct network.
• Verify that the Wi-Fi network settings are correct:
  • Tap Settings > Wi-Fi.
  • Locate the Wi-Fi network you are currently using and tap
    

• You can configure network-specific settings, including IP address, DNS, and Search Domain settings.
• Use "Forget this Network" to reset settings for this particular Wi-Fi network, including the password. This is also useful if you identify a network issue and want to prevent the device from automatically using this network in the future.
• Use "Renew Lease" to acquire new IP address, DNS, and Search Domain information from the Wi-Fi network.
• Note: If the Wi-Fi network uses MAC address filtering, you will need to add the MAC address to the access list for the Wi-Fi router. The MAC address for your device is listed as the Wi-Fi Address in Settings > General > About.

If you are still unable to join a Wi-Fi network, or are unable to access the Internet while connected, try the following

• Restart the device
  • Hold the power button until "slide to power off" appears. Slide to power off your device. When it is off, press the power button to turn it back on.
• Reset network settings by selecting Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings, including passwords, VPN, and APN settings.
• iPhone only: If you continue to experience issues, consider turning off Wi-Fi and using the cellular data connection instead of Wi-Fi.

Additional Information If using a Wi-Fi router at home, refer to your user manual/documentation to assist you with some of these suggestions.

• Check the manufacturer's website for your Wi-Fi router for firmware or software updates.
• Verify the Wi-Fi router can broadcast an 802.11b/g signal. If using a 802.11n Wi-Fi router, consult the manual/documentation for how to configure the Wi-Fi router for 802.11b/g compatibility.
• If you are using multiple WEP keys on your Wi-Fi router, try configuring your Wi-Fi router to use only a single WEP key.
• Try or resetting (or turning off and then on again) your Wi-Fi router. Note: If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
• Disable wireless encryption or security on the Wi-Fi router to rule out encryption issues. If this resolves the issue, try using a different encryption or security protocol.
