WPA issues

I havd a Dell Latitude D600 with wimdows xp os and service pack 2. I can see the wireless network in my school but can not connect to it. Each time i tried to connect it wrote " WPA not supported by your wireless adapter ". Please what do i do to connect to this wireless. Thank you.

 

You most likely either have an older wireless card - an older b model not supported with wep or older sofware for the card

Here is the link to the Dell networking Drivers for your laptop

Update the driver
It is usually either the broadcom or Intel yet called a dell
You can go to intel directly for perhaps newer drivers
If it is a b card and there is no support for WPA
you can update the card - buy one on ebay
You will have to snap the little pins in - and that is a trick sometimes
Remember to take the battery out
or easier you can buy a G PCMCIA credit card network adapter - few want these now as newer laptops either have usb and none of these slots
or a usb network adapter
It all depends on your skills
Its a nice , well running laptop
If you do a manual choice windows update - it may find the new driver for you as well

 

My wireless adapter is OrioNOco Wireless LAN Pc Card (3.3 Volt) by Lucent Technologies.

 

If after following TonyT's advice and your Wireless Adapter is compatible with WPA with updated drivers (all wireless adapters are WEP compatible) then I'd suggest asking your schools IT department for assistance, it's unlikely they'll downgrade from WPA to WEP though so don't expect miracles.

 

Please how can i upgrade the wireless adapter to be compatible with WPA. Please help me. Thanks.

Below has nothing to do with post # 5.
I doubt that you can upgrade your adapter. You could just disable it and buy you one of those USB type adapters and go that route.
