It appear on the screen data connection refused, and i sometimes do not get coverage from the network. how can that vanish from my home screen

how are you checking this speed.
the speed you appear to be quoting at the computer is the speed the lan network socket is running at. it's probably rated at 10/100
some peripherals only have a 10M interface hence you only get a 10M reading and sometimes will slow the whole network down.
not sure what you mean when you send your network 'through the wall'. if that's using a powerline adapter, the connection between them often only runs at 10M. I've got 500m powerlines and they're often down to 10M, sometimes 100M but not very often.

Hello,

You have to ocnnect your iphone to internet first , Follow below step to connect to internet

When you use any Internet enabled application, iPhone does the following in order until connected:

1. Connects over the last Wi-Fi network you used that's available.
2. If no Wi-Fi networks you've used are available, shows a list of Wi-Fi networks in range. Tap a network and, if necessary, enter the password to join. Networks that require a password show next to them.
3. If no Wi-Fi networks are available or you choose not to join any, iPhone connects over the cellular data network.

Note: You can be on a call and use Wi-Fi or 3G1 at the same time. Other cellular data networks are unavailable while you're on a call.
Wi-Fi

• Wi-Fi is often faster than cellular data networks. Wi-Fi networks cover limited areas. iPhone can join AirPort and other Wi-Fi networks at home, at work, or at Wi-Fi hot spots around the world.
  When iPhone is connected to a Wi-Fi network, the Wi-Fi icon in the status bar at the top of the screen shows connection strength. The more bars you see, the stronger the connection.
• To see all the Wi-Fi networks in range, from the Home screen choose Settings > Wi-Fi. Tap a network to join it.
• Many Wi-Fi networks can be used free of charge, and some require a fee. To join a Wi-Fi network at a hot spot where charges apply, in most cases you can open Safari to see a webpage that allows you to sign up for service.

For information about configuring Wi-Fi settings, see the "Wi-Fi" section of the iPhone User's Guide.
Note: iOS devices sold in China may use the term Wireless LAN (WLAN) instead of Wi-Fi. Not all China iPhone models support WLAN; see this article for more information.
Cellular data networks

• Cellular data networks allow Internet connectivity over the cellular network. Check your carrier's network coverage in your area for availability.
  You can tell iPhone is connected to the Internet over a cellular data network if you see , or in the status bar at the top of the screen.
  If you're outside your carrier's network, you may be able to use a cellular data network from another carrier. Roaming charges may apply.
  Note: If not on 3G, while iPhone is actively transferring data over the cellular data network-downloading a webpage, for example-you may not be able to receive calls. Incoming calls may go to voicemail.
  

I hope , after this , you will be able to connect to Internet....

Thanks
Sandeep

#1 Your BlackBerry does not have sufficient Power
Check the battery charge level as shown by the battery icon on the top left of the home screen. No Power - Battery Charge Indicator does not show a charge or is very weak. The battery icon may be red. Charge the battery.
#2 You are Out of Network coverage area
Check the Signal Strength Indicator on the home screen. (1 to 5 bars, as shown below, indicating signal strength). If there is no signal, you may be out of range of the network.
If you are sure you are in range of the network, but show no signal strength, press Alt-Right Shift-Del at the same time. This will cause the BlackBerry to reacquire a network connection.
The process for this procedure is:

• Press Alt-Right Shift-Del (The Del key is also the Backspace key.)
• The screen will go blank, and an hourglass will appear. Wait for the hourglass to go away.
• The startup screen will appear. Wait for it to go away.
• A screen that says Verifying Security Software will appear. Wait for it to go away.
• Check the Radio Tower icon.

If you are in Coverage Area of your Service Provider, You will get the network.
#3 Your Data plan is switched Off.

Hi,
Wireless local area network is a local area network that uses high frequency radio signals to transmit and receive data over distances of a few hundred feet, uses ethernet protocol.

In simple word allow you to surf internet without any internet cable connection, Wi-Fi enabled device such as a personal computer, video game console, smartphone or digital audio player can connect to the Internet when within range of a wireless network connected to the Internet. The coverage of one or more (interconnected) access points called hotspots, can comprise an area as small as a few rooms or as large as many square miles. Coverage in the larger area may depend on a group of access points with overlapping coverage.

In addition to private use in homes and offices, Wi-Fi can provide public access at Wi-Fi hotspots provided either free-of-charge or to subscribers to various commercial services. Organizations and businesses - such as those running airports, hotels and restaurants - often provide free-use hotspots to attract or assist clients. Enthusiasts or authorities who wish to provide services or even to promote business in selected areas sometimes provide free Wi-Fi access.


Thanks....!!!

Hi,

After cancelling the data plan with the wireless service provider, the message Data connection refused appears at the top of the Home screen on the BlackBerry smartphone instead of the branding of the wireless service provider.

This is caused may be you were previously subscribed to a data plan through a wireless service provider, and the BlackBerry smartphone is still configured to attempt to access the data network.

To resolve this issue, you need to turn off the Data Services feature on the BlackBerry smartphone. To perform this, you need to complete the following steps:

1. From the Home screen, open the Options menu.
2. Click on Mobile Network or Network.
3. Set the value of the Data Services field to Off.
4. Open the menu and select Save.
5. Return to the Home screen.
6. Turn the wireless transceiver off and then on again.

To enable (turn on) the wireless transceiver on the BlackBerry device, go to the Home screen and select the Turn Wireless On icon or open Manage Connections and select the wireless connection to be enabled. Once enabled, the icon will display Turn Wireless Off .

To disable (turn off) the wireless transceiver, go to the Home screen and select the Turn Wireless Off icon or open Manage Connections and select the wireless connect to be disabled. Once disabled, the icon will display Turn Wireless On.

I Hope it helped you.

Thank you for using ' Fixya ' and have a nice day!!

See if this works....

-Press menu key
-Click OPTIONS
-Select Mobile Network
-Click on "START PROVISIONING"

It should give you a message saying: PROVISIONING COMPLETED SUCCESFULLY.

You wont need a MSL code if you do it this way.

go to setting and turn on wireless visibility on

In Networks select (only) GSM instead of both. It must be looking for UMTS network first and no finding any it gives the error.

my screen is not appearing it started last four moths after some few minutes the time comes and when any of the key pad is pushed sudden it will vanish and the screen turns white.
