Unable to connect to wireless network


I have just had new wifi installed on my network. It is WPA/PSK authentication and TKIP encrypted. The network is broadcasting. My laptop with XP SP3 connected fine and work with the connection, but I have10 PC's with XP SP2 that can find the network, but if you try to connected a mesag pops up with:

"Windows is unable to connect to the selected network. The network may no longer be in range. Please refresh the list of available networks, and try to connect again."

I've tried inputting all connetio detailsthrough properties, but this does not seem to help. Any ideas?

One possibility is that the wireless network is set to use shared authentication. The Windows XP wireless service assumes that all the WAPs it detects use open authentication. With shared authentication, you have to know the key (password) set by your friend on the WAP. Here's how to configure your computer to connect to a network that uses shared authentication:

Click Start | Connect to | Show All Connections.
Double click the icon for your wireless network adapter.
Click the General tab, then click the Properties button.
Click the Wireless Networks tab.
Click the Add button.
Enter the SSID (network name) that's set in the network's WAP.
Under Network Authentication, select Shared.
Uncheck the checkbox that says "The key is provided for me automatically."
In the Network Key box, type the key set on the WAP, and type it again in the Confirm Network Key box.
Click OK.
This should allow you to connect to your the wireless network.

the network authenication is not shared it is WPA/PSK.

The machines have Marvell Libertas 802.11g SoftAP wireless cards installed. Could it be that these cards do not support WPA-PSK with TKIP encryption?

Do You Have a Trusted Wireless Environment?

A Trusted Wireless Environment is a framework for building a complete Wi-Fi network that is fast, easy to manage, and secure.

You should try to install this patch:
SP3 for XP already has the patch included, maybe that's why your sp3 machine can connect.

I am not at the site at the moment, but will try that. I fear it will not work though as I did install SP3 on one of the machines that wasn't connecting and it still couldn't connect.

Encase the patch doesn't work, does anyone have any other suggestions?
To support WPA-PSK you would need the patch from Microsoft for Windows XP. After that it usually works.

I tried the patch and all updates and it turns out the card is old and cannot support WPA-PSK authentication. I tried a new card and it worked fine.
