Cant connect to wifi

Depends on what dell you have. I need more information.. but i can say this much, wifi connections can be turned on and off by a switch. Check to see where the switch is for your model of dell.

Check whether the device is installed properly or not in device manager...also check on the laptop there would be a wifi switch..its a verticsl line with three fringes on the top...turn it on by pressing...that wifi switch can also be clubbed with the normal keys so press fn key and then press the wifi key...then try to connect

the wireless switch is located on the right side of the laptop, just under the only USB port of the machine.

First, turn the wireless switch OFF and switch it back ON
(make sure sure that there is a BLUE light on the wireless indicator)
then press Fn+F5 (this will ENABLE the wireless capability of your computer)

Sometimes the switch on the front of Acer laptops is not switched on to get WiFi. Is there a Wifi light on for it?

check this URL, http://support.acer.com/acerpanam/manuals/acer/0000/userguides/Aspire_4315-4715Z_UG_EN.pdf

and make sure the wifi switch is toggled to turn on/enable the wifi device.

In connecting through a wifi, there are two factors to consider. (1) Wireless Router broadcast and (2) Wireless Receiver.

Make sure that your network router is broadcasting wireless internet or wifi. Also, you have to know if you need a pass key or password in order to connect to the wireless network.

Now, given that there is a wifi spot, your laptop should automatically recognize the wifi broadcast and negotiate connection without your intervention. This will only happen IF AND ONLY IF your laptop has a wifi radio receiver and that it is TURNED ON. When it is turned ON, it will connect you immediately if the network has no pass key set. If there is, then you have to enter that key when you try to manually connect it. (Right click on wireless network icon on system tray. Then it should say: Wireless Network Available. Then Click CONNECT)

To turn your wifi radio receiver ON, slide a switch button to ON position depending on your laptop model. If you dont have that kind of switch, look for the wifi icon printed in the keyboard keys. In some laptop, it is in F2. Now Press FN+F2 to turn wifi radio receiever ON and OFF.

Did you try - after switching on the "antenna switch" or WiFi hardware - to "Enable" the WiFi adapter, under (XP) Start - Settings - Network Connections - LAN or High-Speed Internet - Wireless Network Connection? (select, right click and select Enable)?

p.s. Once your WiFi hardware is recognized (by Win XP) there is (should be) always a "Wireless Network Connection" in your Network Connections, enabled or disabled, active or not.
