Any 802.11i laptop cards yet?

Hi All,

Are there any 802.11i laptop cards out there (for sale) yet?
Is there some hold up? (Do you have a favorite?)

Many thanks,
--Tony

May not be in the US yet, but go to
http://www.asia.manufacturers.global...0000057010.htm

That was an article from back in October of 2004 saying they will be made,
right hand side is a product locater.

There are several 802.11i ready cards, netgear wag11, dlink dwl650,
proxim orinoco gold and silvers are a few.
The only thing 802.11i provides that WPA didnt is AES encryption.
Most cards have an AES encrytpion option and can be used but the
encryption
may be done through software. The later cards have added a hardware
encrytion processor to speed
things up. Regular ole WPA using 802.1x and the RC4 encryption (which
has nevr been cracked)
is probably just as secure but goverment agencies require AES, thus
AES.

It's not clear to me that you need a special NIC to use 802.11i, although a
special AP is probably required.
802.11i is not a modulation scheme, and so does not replace 802.11a or
802.11g. 802.11i is a security protocol that is used in conjunction with
802.11a or 802.11g. 802.11i uses Advanced Encryption Standard (AES), which
requires more CPU power than WEP or WPA version 1. Some existing APs won't
have the horsepower. Network Interface Cards (NICs) may be a different
story. If the processor on the NIC is too wimpy, a vendor could have the
system CPU do the encryption instead. Only time will tell if any
manufacturers actually do that. History tells us that they won't, since
almost no manufacturers produced new firmware to support WPA on 802.11b NICs
or APs, despite the fact that WPAv1 was specifically designed so that older
processors could keep up. They would rather force your product into
obsolescence to make another sale.

802.11i, which I believe is the same thing as WPA version 2, will require
you to have an Authentication Server, like RADIUS. This is really intended
as an enterprise solution, and not for homes. Just as with WPAv1, I imagine
that you'll not only need a compliant AP and a compliant NIC driver, but
you'll probably also need a compliant OS (supplicant). A quick search on
Microsoft's site didn't make clear what is their readiness for 802.11i.

Linksys, Netgear, 3Com, DLink all have cards that support 802.11i
(WPA2).
As with WPA there is both a Passphrase and a Radius option. The main
difference
in WPA and WPA2 is the AES encrption which is allready supported on
many
cards. As mentioned though the WPA2 cards may have another processor
to
handle the encrypting.

Having done a little more homework, I can share this distinction between
WPA2 and 802.11i:
WPA2 is the approved Wi-Fi Alliance (wi-fi.org) interoperable implementation
of 802.11i. WPA2 implements the MANDATORY elements of 802.11i.
The Wi-Fi Alliance has been certifying products for WPA2 since 1 Sept. 2004.
WPA2 does have both Personal and Enterprise versions; a product may be
certified for one or for both. The Personal version does not require an
authentication server like RADIUS.
