Wireless Cards and Encryption

May appear to be a stupid question but is the type of encryption on wireless cards software or hardware coded in? Do all cards use WPA?
I have an old Acer laptop with inprocomm i2220 wireless card in which I can't seem to get connected on anything other than wep making it weaken my network. I'm looking to use the strongest security I can but how do you find which type is supported by the card?
I was thinking that the card would just pick up the signal and the logarithms etc would be software related.

It will largely depend on the drivers which in turn may be limited by the underlying hardware.
I have some older wireless devices that only support WEP.

That was my worry, I found this http://downloads.amilda.org/docs/datasheets/IPN2220%20PB_031204.pdf bottom left it does say WPA not sure if I would have to find some different drivers than from the Acer site though.

Re: Wireless Cards and Encryption

If you're happy to fiddle a bit then check to see if the wireless adapter is a standard removeable mini-pci adapter under a hatch somewhere. If it is then you've the option of getting a replacement adapter off Ebay or somewhere. They're usually pretty cheap (eg http://cgi.ebay.co.uk/Intel-3945ABG-Mini-PCI-Wireless-Card-/250699706442?pt=UK_Computing_LaptopAcces...) and if you stick to one of the better known makes like Intel or Broadcom then getting drivers shouldn't be a problem.
(This route can also be used to upgrade an older laptop to 802.11n)
Alternatively get a USB wireless adapter.

Thanks MRC that's the route I think I'll go down, I don't mind a fiddle  Grin There's pull out for adding PCMIA cards on the side so may be just a case of disabling the one in there and inserting another.

Ah, if it's PCMCIA (not mini-pci) then that's even easier  Smiley

Re: Wireless Cards and Encryption

There is a PCMCIA slot available, the one that's in is mini-pci I think. If its easy enough to get out I will if not I might just disable it.
