Wi=Fi connection I am trying to connect using a Palm wi-fi card, however, I get so far in the connection process and then it tells me that there is no signal. Do I need to call my isp, or is there something that I am not doing correctly?

Vodafone wi fi router would create wi fi that you would connect up to 10 computers to a generated wi fi access . p.c ---- >>>>> wi fi ==== Mobile data - vodafone p.c2 --- >>>>> wi fi reminder card should tell you ssid and authenication code . http://support.vodafone.com.au/resource/1390189496000/PocketWiFi4Guserguide

camera distance may be too far from wi fi source ie router or access point ? possible solution use a wi fi range extender.
Neighbours Wi Fi interfering with your WI FI . possible solution change the channel used by your wi fi from auto to channel 3 or channel 6 . This ensures channel spacing from neighbors if they are on auto as well . Setting in wi fi access point or wi fi router

Do you have other devices such as tablets, notebook, PC, or smart devices on the same Wi-Fi network? Do they have a similar problem?

Try logging on to a different Wi-Fi network such as free services in some shops and stores. If you cannot connect anywhere, your phone may be bad.

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

The password that my Iphone required was the 20 digit key located on the sticker as WPA-PSK. Hope this helps someone!

Wi-Fi Functionality

1. Connects over the last Wi-Fi network you used that's available.
2. If no Wi-Fi networks you've used are available, iPod touch will scan for Wi-Fi networks and show 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 a lock icon () next to them.
3. Option to manually enter your Wi-Fi network name/SSID (if the Wi-Fi network is configured not to broadcast or be displayed to the public). If necessary, enter the password to join.

When iPod touch 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.
Wi-Fi Settings

1. Turn Wi-Fi on or off.
   Choose Settings > Wi-Fi and turn Wi-Fi on or off.
2. Set iPod touch to ask if you want to join a new Wi-Fi network.
   When you are trying to access the Internet, by using Safari or YouTube for example, and you are not in range of a Wi-Fi network you have previously used, this option tells iPod touch to look for another network. iPod touch will display a list of all available Wi-Fi networks that you can choose from. Networks that require a password appear with a lock icon ().
   
   If "Ask to Join Networks" is turned off, you must manually join a network to connect to the Internet when a previously used network is unavailable.
   
   Choose Wi-Fi and turn "Ask to Join Networks" on or off. If you turn "Ask to Join Networks" off, you must join new networks manually.
3. Join a Wi-Fi network manually.
   Choose Wi-Fi, wait a moment as iPod touch detects networks in range, then choose a network. If necessary, enter a password and tap Join. Networks that require a password appear with a lock icon.
4. Make iPod touch forget a network, so that the device doesn't join it automatically. Choose Wi-Fi and tap the arrow () next to a network you've joined before. Then tap "Forget this Network."
5. Connect to a closed Wi-Fi network (an available Wi-Fi network that isn't shown in the list of scanned networks).
   Choose Wi-Fi, then tap Other and enter the network name. If the network requires a password, choose 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. Ask the network administrator which settings to use.
6. Adjust settings to connect to a Wi-Fi network
   Choose Wi-Fi, then tap the arrow () next to a network.
