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.

My samsung E250i network problem no network showing on display.as well no network found

To view the wireless network connection dialog box, follow these steps:

1. Click Start, Run, and type ncpa.cpl, and then click Ok.
2. Right-click the Wireless Network Connection icon, and then choose Properties. (Or you can right click the Wireless Network Connection icon and choose View Available Wireless Networks from the shortcut menu.)
3. Click the Wireless Networks tab.
4. Under Available networks, click the View Wireless Networks button.

From the wireless network dialog box, you can refresh the network list. This performs another scan of wireless networks within range. The wireless network connection dialog displays the following for each detected network. The following shows the new connection box.

When the wireless network adapter displays the detected networks, you'll able to select a wireless network name and attempt to connect to it. The antenna icon indicates an infrastructure mode wireless network. The icon that shows two wireless client computers indicates an ad hoc wireless connection.

The lock icon and the "Security-enabled wireless network" label indicate that the wireless network has security enabled. The gold lock means you need a network key in order for you to connect to a wireless network. If it's not security enabled, you'll be able to connect to the network without a network key.

What operating system are you using? If it's Windows XP, go to Control Panel, Networking, right-click on the first network adapter, Properties, then select TCP/IP, Properties and enter the appropriate network settings for the first network. Repeat for the second network adapter and second network.
