Re: wireless connection

You will need to speak to the person in charge of the security enabled network, and obtain the type of wireless security (WEP or WPA) and the password.

You should also determine what security types are supported by your own laptop's wireless connection. If it is an older one, it may only support WEP, and you will be unable to connect to any WPA protected networks.

Wlan card disabled

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.

How do I turn on my laptop in order to use ot wirelessly?


Enable your wireless connections and search for wireless connection that in unsecured or secured connection. For secured connection, you need to encode the WEP password to be able to access into the internet. For unsecured connection, you can connect directly and automatically.

I hope it helps you.

Fix a security problem


To make your wireless connection secure, you have to change the security settings of the wireless connection in your wireless router, not your laptop. Most wireless routers have a "Web Console", basically a web page to set up the router. Make sure you have a network cable handy incase things go wrong, and if possible, your router manual.

To connect to the router, you need the IP Address of the router. To find this, go to your start button, go into "Run...", (for vista click the start search box) then type "CMD" and press Enter.

A black window will come up. In there type "ipconfig" and press enter. It will list your Network connection details. The one you are interested in is "Default Gateway", under "Wireless LAN Adapter", note this IP address. It's usually something like, or, but can be a variation on that theme.

Onceyou have the IP address, close this window, and then open Internet Explorer, or Firefox if that's your preference. in the address bar, where you type web addresses, type in the IP address noted earlier. All being well, you will either be prompted for a password, or be taken to the main screen of the router where you can log in. The manual for the router should have the login name and password, usually "Admin" for the username" and "password" for the password. If you dont have the manual, and the above name and password doesn't get you in, Google your router model, and put password in the end of the search IE "Netgear DG834G password" and you should be able to find the default for your model.

Once Logged in, you need to feel your way about the settings, as its very router dependant, but you basically are looking for the wireless security settings. You want to enable WPA and give it a password, then apply. Once you do this, you will loose your network connection. On your windows laptop, you want to go to your wireless connection, disconnect if it still shows connected, then look for your network, you'll know your SSID, its the name that came up with unsecured next to it. Click it, then click connect, and all being well, it should ask for a password. Enter the password you put in the router for WPA, you will need to enter it twice. t should then connect after a minute or so, and you now have a secure connection!.

If this goes wrong, you will need to connect your PC to the router using the network cable, and go into the web console again, ang check the password, and security settings in the router, that way you won't be stuck if it doesn't work, You can always turn security off, or try WEP encryption. It's not as secure, but better than unsecured.

I hope this helps, If you need more help Email me at LateLesley at Yahoo dot co dot uk (Spaced out to avoid spam crawlers, just add the @, dots and take out the spaces :-) )
