Enable / Disable an Enterprise Laptop's Wi-Fi
Wi-Fi, short for Wireless Fidelity, is networking technology that allows you to connect to the Internet. If you have a wireless-enabled Latitude computer you can connect to the Internet when in range of an access point called a hotspot.
When not in use your Latitude's wireless card should be disabled. By disabling Wi-Fi, you will receive two benefits:
Start-up times will be much faster.
If the wireless card is ON and you are out of the office (not connected to your normal, wired connection), the laptop will try to use the Wi-Fi network during the login process to run the various start-up scripts, etc. It will eventually time-out (fail). By having the wireless card turned OFF, the start-up process will be much faster.
Computer will not continually search for a wireless network (and waste battery life).
If you are in the office (connected to your normal, wired connection) or in a location where there is no wireless hotspot, you don't need to have the computer waste processing power by looking and looking for a wireless hotspot. By disabling Wi-Fi, you will gain a little more power for your other tasks. In addition, you will maximize your battery operating time by disabling wireless activity.
NOTE: After your Latitude has started up completely, you can ENABLE the wireless card and connect to a wireless hotspot. For example, a wireless router at your home or at a local coffee shop. If you have connected to this hotspot previously, the wireless card should connect automatically for you.
NOTE: Once you have the wireless card enabled, before you shut down the computer, you should again DISABLE the card. The computer will then be ready for the next time you turn it on with wireless turned off.
Enable / Disable with Hardware Switch
The more recent Latitude models have a wireless switch to enable or disable wireless network devices and the
Wi-Fi Catcher Network Locator.
Dell Latitude E6420 and E6520 Series
These laptops have a small switch on the RIGHT side of the keyboard. The switch is toward the front of the laptop. The Wi-Fi Catcher™ icon will is above the keyboard. You will see a lit radio tower if the wireless switch is enable
First what type of PC and operating system is running on it.
Do you have a active contact with a cell phone compony?
if so make sure you have your iPhone fully charged.
You said that your iPhone is "Disable" do you mean it is locked up?
If so do a reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo
Then after it powers back up go into "Settings" then go into Wi-Fi and connect to your Wi-Fi or if you don't have one you can go to most fast food places and use their Wi-Fi.
Then after getting connected to a Wi-Fi go back into "Settings" and then go into General" and then into "Software Update" to check to see if you have a update to install. If so install it.
Then go back into "Settings" and click on "iCloud" and log into it with your Apple ID and then and make sure your settings are correct that you had before. If you have not done so turn on backup so you can backup to the cloud till you get a system that will allow you to install iTunes.

hi,
plz type " ncpa.cpl " in run command, it'll shows the network connections. if the wireless (WI-FI) driver is updated, it'll shows in that screen. just move the cursor to wi-fi connection and right click it. it might have been disabled. if it is disabled plz enable it and switch it on ur WI-FI switch...
McAfee has controls that can lock you out of the internet. Are you trying to connect via wi-fi or ethernet cable? If it is wi-fi, try disabling McAfee, connect to your wi-fi then turn it back on. You'll need to make an exception for that connection. If wired, disable McAfee, make an exception for port 80, 8080, 23.
Well since you jailbraked your iPhone you can not use wi-fi because jailbreak disables that future what you can do is restore your iPhone to factory settings.
Thank You,
Apple Care Technical Support
