This Work for me just fine thanks :)

Hi there,

I googled a bit around this phrase, but didn't find a good answer.

I am using WPA-PSK with EAS encryption (WPA2) to connect my wireless
clients to a 802.11n draft router (D-link DIR-655). The connection works
as advertised, but I keep getting this message bubble, just a second
before the connection is made.

I read that it's related to Windows Wireless Zero configuration (WZC),
with no preferred networks specified, but in my case I specified the
network SSID. Someone suggested on a forum to quit using WZC and use the
manufacturer's provided configuration utility.

What to do you suggest ? Will it remove the annoying message bubble ?
Any advantage of the manufacturer's utility over WZC ?

Lorenzo

Hi Lem,

Trouble is, the option is greyed out if I select WPA-PSK (TKIP or EAS).
It can be selected only if select "WPA - professional"...

Lorenzo,

You write that you are using "WPA-PSK with EAS encryption (WPA2)."
Although WPA-PSK with AES encryption uses the encryption algorithm
specified for WPA2, it does not have all of the security features of
WPA2. There is no reason I know of why WPA-PSK (AES) should be looking
for a certificate (certificates should only be required when using
WPA-Enterprise), however, if you do not have an option in Wireless Zero
Configuration for WPA2, you should download and install
Wireless Client Update for Windows XP with Service Pack 2
http://support.microsoft.com/?kbid=917021

Alternatively, use the configuration utility for your wireless adapter.
Be sure to disable WZC if you do this. There may be an option in the
mfr's utility that will do this for you, or you will have to do it
manually, such as described at http://www.ezlan.net/wzc.html

In addition, both ends of your wireless connection -- router and adapter
-- need to have the same security configuration. In addition to making
sure that your adapter is set to use WPA-PSK (AES) (or WPA2-PSK), you
also need to make sure that your DIR-655 is not configured to use
WPA2-Enterprise. Double check this in the configuration utility of your
DIR-655.

I removed the latest driver for the DWA-645 card, and re-installed from
the CD, along with the D-link wireless utility.

I disabled the windows wireless zero configuration, and configured the
encryption to WPA2-PSK (AES), with now a perfectly working setup and no
more warning bubbles. And 300Mbps is availbale even with WPA-PSK (TKIP)
now, while it sed to fall back to 54 Mbps with the "latest driver" from
D-link Finland.

Thanks to all for your input.
