Under the wifi setting, I show to be connected, but my iphone still shows 3g on the top right, not the wifi setting. Any suggests?

What Type/Brand of router ?????

Apple's iPhone is a multimedia connectivity tool.
As such, the iPhone employs a sophisticated system to keep you connected to the web via WiFi signals so that you can stay up to date with email, mapping and media.
To use the iPhone's WiFi feature just follow these steps.
Tap a network.
If you have not yet used your iPhone's WiFi or if you're in a new WiFi area, the iPhone will show you a list of available networks.
Tap the network that you want to connect to in order to connect.
If there is a password required a little lock icon appears.
Enter the password to connect to locked networks and continue to surf the web.
Monitor your signal.
As you use your iPhone, especially if you're moving around, you should take a look at the signal strength of the connection.
The strength is indicated by a small, black broadcast symbol that stacks arches, or rounded bars, on top of one another.
The more bars there are the better the signal.

Make connecting to WiFi automatic or manual.
The iPhone is equipped to automatically search for available networks and connect you to one.
If you do not want the phone to search for networks, select the "WiFi" option on the phone's menu.
Then select either the on or off option of the "Ask To Join Networks."
Turning this option off requires that you find networks manually.

Forget a network.
Once you connect to a WiFi network once the iPhone automatically remembers the network and connects you to it at a later opportunity.
To forget a network so you don't get automatically connected choose the "WiFi" option on the menu.
Then tap the right arrow button next to one of the networks that the iPhone already remembers. Then tap "Forget This Network" to erase the phone's memory of the network.

Troubleshoot Wi-Fi Connection Problems on an iPhone
If you experience Wi-Fi connectivity issues on your iPhone, you may need to reset the Wi-Fi connection.
Your connectivity issues could be caused by the wrong password if you are having trouble logging into the Wi-Fi network or from a problem in your iPhone's settings.
By resetting the Wi-Fi connection, you are clearing out the previous settings created when you first connected to the network.

Tap the Settings icon on the iPhone's home screen, and tap the Wi-Fi tab.
Swipe the switch on the Wi-Fi tab to ensure Wi-Fi is enabled on your iPhone.
Tap the blue arrow button on the network tab you are connected to in the network list, and tap "Forget this Network."
Tap the "Forget Network" button that appears on the pop-up menu to confirm the action.

Tap the Wi-Fi Networks tab in the upper-left corner to return to the previous screen, and tap the network's tab in the network list to re-join it.
Press the Home button on the iPhone, and tap the Safari icon on the home screen to test the Wi-Fi connection.
Tap the blue arrow icon on the network's tab if the connectivity problem persists, and tap the "Renew Lease" button at the bottom of the network's window.
Tap the "Renew Lease" button on the pop-up box to confirm the action.
Tap the Home button on the iPhone, and tap the Safari icon on the home screen to test the network connection.

In order to work (both when registering and dialing), your iPhone will need to make a data connection to the RingFree servers. Wi-Fi, though not always available, of course, is your best choice.
To enable Wi-Fi on your iPhone:

1. Go to the Home screen by pressing the Home button or by unlocking your phone.
2. Touch the settings incon
3. Look to the right of the Wi-Fi icon. If a Wi-Fi network is listed, you're all set. Otherwise, select the Wi-Fi icon.
4. If Wi-Fi is "OFF", touch the Wi-Fi toggle to turn on Wi-Fi.
5. Then select a network (if one is available) from the list that appears on the iPhone.
6. When connected via Wi-Fi, you'll see a striped upside-down triangle to the right of your service provider's name on the upper-left corner of the iPhone. If there is no network available, you'll have to use the EDGE network.

i hope it will help you for further query feel free to contact.....waiting forward for your reply.....

Hello Jane,

When using a Wi-Fi network with your iPhone, you may occasionally encounter the following issues,Unable to locate or join a nearby Wi-Fi network,Weak or low Wi-Fi signal strength,Connected to Wi-Fi network, but unable to access the Internet.
Tap Settings > Wi-Fi and turn Wi-Fi off and then on again. Verify that you are in range of your Wi-Fi router or base station. Confirm that your Wi-Fi router and Cable/DSL modem are connected to power and turned on. Check whether other devices (portable computers, for example) are able to connect to the Wi-Fi network and access the Internet. Update your Wi-Fi router to the latest firmware.

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

Wi-Fi settings determine whether iPhone uses local Wi-Fi networks to connect to the Internet.
Turn Wi-Fi on: Choose Wi-Fi and turn Wi-Fi on.
Join a Wi-Fi network: Choose Wi-Fi, wait a moment as iPhone detects networks in range, then select a network. If necessary, enter a password and tap Join (networks that require a password appear with a lock icon).
Once you join a Wi-Fi network manually, iPhone automatically joins it whenever the network is in range. If more than one previously used network is in range, iPhone joins the one last used. When iPhone is joined to a Wi-Fi network, the Wi-Fi icon in the status bar at the top of the screen shows signal strength. The more bars you see, the stronger the signal. Set iPhone to ask if you want to join a new network: Choose Wi-Fi and turn "Ask to Join Networks" on or off. Join a closed Wi-Fi network: To join a Wi-Fi network that isn't shown in the list of scanned networks, choose Wi-Fi > Other, then enter the network name. If the network requires a password, tap Security, tap the type of security the network uses, and enter the password. You must already know the network name, password, and security type to connect to a closed network. Some Wi-Fi networks may require you to enter or adjust additional settings, such as a client ID or static IP address. You can type it manually by login onto the Belkin's network page using the browser and by copying the static and dynamic IP address.
