One of the features that makes laptop computers desirable is
their ability to connect to Wi-Fi networks, thus allowing people who are on the
go to be able to check email, browse the web or update social networking status
any time they are in a Wi-Fi hot spot.
Fortunately, enabling Wi-Fi on a laptop is simple to do.
Only basic Internet and computer expertise is needed to
connect your laptop to a wireless network.
Click on the "Start" menu on the bottom left-hand side of your

The Dell Latitude E6400 laptop comes with an Intel Core 2 Duo processor for fast computing and an NVIDIA graphics card for video playback, gaming and Web browsing. The laptop has a built in Wi-Fi card, letting you connect to the Internet on-the-go. However, if you're unfamiliar with Dell or the laptop's factory installed Windows Vista operating system, you might not know how to enable to Wi-Fi.
Slide the switch on the side of the laptop toward the front of the laptop. This switch enables Wi-Fi connectivity on the Dell Latitude E6400. When switched into the back position, the Wi-Fi is turned off. Turn on your Dell Latitude E6400 laptop and log into Windows Vista. Click on the Windows "Start" button. Click on "Wireless," located in the Start menu's "Show" list. A list of currently broadcasting wireless networks appears on screen. With your Wi-Fi enabled, you can connect to any of these available networks. Secured networks ask you for a password when you click "Connect," while unsecured networks connect automatically.
Check if the wi-fi card is properly installed under Device Manager. Go to Start then look for Control Panel on the right pane. Under Control Panel look for System and Maintenance and then click on Device Manager. Now under Device Manager look for Network Adapters and collapse or click the arrow next to it. Check if your wi-fi adapter is installed(10/100 or 10/1000 is your LAN adapter, wi-fi adapters usually indicates something like 802.11x(could be agn or g or b) or the word "wireless". If you don't see anything I mentioned above that means your computer is unable to detect any wi-fi adapters installed. Know if you found a wi-fi adapter but there is a yellow exclamation or question mark, all you have to do is re-install the drivers for your wi-fi adapter(you can download the drivers on the Compaq website for free.)
Check if the wi-fi is disabled or stopped, if you have a bulit in wi-fi adapter on your laptop they have a wi-fi switch on the side or near the function keys(F1, F2, F3 up to F12). Wi-fi button/switch will have a logo or marking of an antenna that has waves coming out of it and there is a LED light that will indicate if its on or off(for Comapaq laptops it's either a blue button at the front, near the function keys or at the front panel on the buttom edge.
If both fails then you may need to contact Compaq for further assistance.
Hope this will help you fixin the wi-fi problems on your laptop.
please note that there are 3 possible wireless network cards in this laptop, I sugest you download all, and try each in the following order
remember to uninstall each driver if it is not correct
If you are runing XP, you will need to try and locate the relevant 3 XP drivers from the 3 manufactures sites EG: Intel
Not much offered at Compaq's driver site for XP. For the modem driver, try the link below, it says it's for Vista, but it should work. If it doesn't then you will need the make and model of the modem, then go to the manufacturer's site or driverguide.com for the drivers, and the same for the wireless, make and model, manufacturer's site or driver guide. To be honest with you, modems are just about obsolete, unless you have dial up at home, you'll probably never use it.
