No wifi can fujitsu siemens lifebook s 5582 connect wireless to my router or needs a wireless network adapter ?this is called pcmcia ?on my network connections there is no icon "wireless connection" under high speed internet

Unplug, remove battery, plug in, reboot. The software should ID the hardware and apply the generic driver. Try here for the Wireless adapter driver: http://support.ts.fujitsu.com/download/DeskUpdateLink.asp?SoftwareGUID=CB18BE72-A5E5-42D4-98DB-4700CA3C4C3E&Prod=LIFEBOOK%20S7220&Produktdetail= Open the Device Manager, select Network Adapters, is the Wireless adapter listed, enabled?

If you are trying to connect to a free WiFi network site try the Airport. Macdonalds, Starbucks etc.
The wireless networks in your area are most likely private wireless networks and if you find one within wireless range you most likely cannot connect into this network without the owner's permission because the connection will be encryption protection (they would need to give you this encryption key).

There could be a switch or alt-button to push in order to turn on the WiFi. After that, search under Wifi connections and choose a network that is broadcasting in your area.

go to command prompt type "ipconfig /all. Then ping your default gateway. If your ping results are successful then the router needs to be powercyled.

Go Fujitsu Website and support, download drivers and download the correct WIRELESS NETWORK DRIVER and/or ADAPTER drives. Select RUN and reinstall them (all).

If that does not work then it may be the network adapter which may be behind a back flap. Remove and Replace with same part. Actually its easier just to buy a USB or PCMCIA Network Adapter from Radio Shack to plug in to your Notebook, comes with software and driver installation disk about $40. This is generally the best solution as it works independantly as a "plug in", easier to install if notebook's built in Network Adapter is defective.

Seems like you have a pretty old laptop. I'm guessing its got a wireless B card installed internally. And wireless B supports WEP most of the time. And if you're lucky the manufacturer of that wireless card may have an update to patch your card so that it will see WAP. Otherwise you can replace that internal card or get a usb / PCMCIA wireless card that supports at least wireless G standard.

What you need to verify is that the wireless adapter is not disabled or turned off. There is a switch on the front edge of the unit that will turn the adapter off and on.
if you go to http://solutions.us.fujitsu.com/www/content/pdf/SupportGuides/S7210_GSG_B5FJ-5241-01EN-00.pdf you can see the picture of where it is, but from the center on teh front edge, where the latch is, moving to the left, is the mic socket, the headphone socket and them the on/off switch you are looking for. slide it the other way and that should get you back on.
If that doesn't turn is back on, verify in the network connections that the adapter is enabled as well.

Have you got your own wireless router and you are trying to connect to it?
To connect to the Internet, you need to have your own wireless router cable or DSL modem that is connected to an Internet Service Provider of your choice.
Most Internet Service Providers can supply the wireless router and a broadband plan that suits your needs. Beware some providers will slug you with excess charges once you exceed your download limit.
Get back to me with details of the Wireless Router and the wireless card in your Fitjitsu laptop and I can advise you how to configure your system to secure your wireless network.

You need to get a wireless adaptor your laptop did not come with wireless built in. You can get a USB adaptor or a PCMCIA adaptor. Either will work but the pcmcia adaptor will be a little faster
