    Tried the F5 and FN keys and it does not enable the external Airnet Wireless modem card. Any other solutions to get the external modem card to work...there is no light on the card when installed.

    And you've already installed the drivers for the card, correct?

    Otherwise you'll have to do that first. If you did and you get no lights then the card or your pcmcia slot on the laptop could be defective.

    Have you used the card before or another card in the same laptop?

Fn + F5, Enable or disable the built-in wireless networking features, this providing that you have installed all the original drivers, otherwise the wireless may not work.

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

Hi there,
First of all you need to see two things in the system 1. Drivers 2. Wireless button Light
1. If the drivers are installed you will see wireless icon in the taskbar bilalseham.jpg
if its not available you can check two things 1. Drivers are installed properly 2. Either its enable or disable
You will see the drivers by right clicking my computer>Manage> Device Manager Right click my Network Places> Properties> wireless network connection right click and select Enable
2. Wireless Button Light Infront of the laptop where you see the Audio Jacks and You see two white buttons (Right one is Wireless Enable/Disable Button) when its Disabled you will not see any light When Enabled you will see Orange light Blinking or stable. Press once and it should get enabled. and if you have installed Launch Manager you will also see notification on screen that WIRELESS ENABLED OR WIRELESS DISABLED
Follow above steps and you will be able to see the wireless connection,

Does not detect any wireless networks even though the wireless is enabled


There may be a button or switch on the side or front that enables the wireless. Look for it first.

If not, the card itself could be popped out (inside) or it is damaged.
