Post subject: Windows XP Pro WPA2
Archived from groups: microsoft>public>windowsxp>general (more info?)
I'm helping a friend who's having difficulty gettting WPA2 WiFi security to
work on his Windows XP Pro Japanese version. He doesn't have WPA2 selection
on his Windows Wireless Network Connection. The only options available are
Open, WEP and WPA (I can't remember exactly). There is no WPA2 selection.

I downloaded KB893357 Japanese version. Installed the patch. Restarted the
PC. I then went back to WiFi settings. There's no WPA2 entry there. I did
exactly the same patching on my XP Home English version. I can see WPA2
option in Windows Wireless Network drop down box after the patch is intalled
(WPA2 doesn't exist without KB893357).

Btw, he's using Buffalo WLI-U2K-AMG54 USB Wireless LAN device. Googling
leads me to (of course) Japanese version of Buffalo product. The only
difference between his notebook and mine is I'm using Intel 2200BG wireless
LAN device. I don't think the issue is his Buffalo wifi NIC inability to use
WPA2. Or is it?

Has anyone come across this problem (after installing KB893357, WPA2 option
is still not there)?

Correction:

I should've said:
The only options available are: Open, Shared, WPA and WPA-PSK

WPA is installed.

Real product numnber is WLI-U2-KAMG54. This product is _not_ WPA2
compliant, and therefore you will be presented the WPA2 options.

You're correct. It's WLI-U2K-AMG54 USB wireless LAN device. I search
buffalotech USA site for similar product. I found WLI-U2-KG54-AI:
http://www.buffalotech.com/products/wireless/wireless-g/wireless-g-key...in-usb-

Indeed it says WPA-PSK (AES, TKIP) and 128/64-bit WEP security support.
There's no mention of WPA2. I guess I'll have to lower the access point
security from WPA2 to WPA-PSK with AES.

For practical purposes, WPA-PSK with AES is equivalent to WPA2. MVP
Jack sometimes calls WPA-PSK with AES "entry level WPA2."

I set my shared key to 50 (random) characters long, including digits,
upper/lower case letters, and some !#$%^&*+-=) characters. You think it's
good enough? It's better than 49 chars long, right? Smile

As Jim stated it really much depends on what you weigh most.

Optimum security or optimum userfriendly.

There are many sites on the internet which can generate a 64bit random
cipher for you. These make a very secure network, since the key for WPA
today can only be bruteforced.

These sites however, also recommend you save the cipher in a text file on a
USB drive or somewhere with easy access.
Simply because a code like
nWlyOJuC.WMH\:!K@a!\&K83LjLex,6)'"ihwU&UI=]U^&t=oRK|U&1}=!R~C%\
can be very hard and tired to enter on multiple PCs or friends who needs to
borrow your internet.

A code like Th!sC0de!sVerySecret4Me may not be quite as strong as the
previous one, but in my sense with a bruteforce attack it would still need
to some hours to crack it.

The main problem with a key like that is that unless you're a very
unusual individual, you'll have to write it down somewhere. A
50-character non-dictionary password that also comprises
non-alphanumeric symbols is overkill -- but that doesn't mean you
shouldn't keep it.

I won't say that there are as many different opinions on optimum key
length as there are cryptographic experts, but there certainly is a
difference of opinion. Here's an article on the topic that's still
interesting, even if it is around 9 years old:
http://www.windowsecurity.com/uplarticle/4/keylength.txt

Note particularly the discussion about the difference between
"passwords" (which is what your 50-character "shared key" really is) and
cryptographic keys. BTW, the AES competition mentioned in the article
was resolved in November 1991.
