Hi
To connect at 128bit, it has to be supported by the Wireless Router (WAP), and the Wireless client card. Check carefully to make sure that they both support it. This page covers WinXP Encryption issues. http://technet.microsoft.com/en-us/library/bb457016.aspx In addition WEP 64 or 128 is Not really secure any more. From the weakest to the strongest, Wireless security capacity is. No Security Switching Off SSID (same has No Security. SSID can be easily sniffed even if it is Off) MAC Filtering______(Band Aid if nothing else is available, MAC number can be easily Spoofed). WEP64____(Easy, to "Break" by knowledgeable people).

WPA-AES__(Not functionally Breakable) WPA2____ (Not functionally Breakable). Note 1: WPA-AES the the current entry level rendition of WPA2. Note 2: If you use WinXP bellow SP3 and did not updated it, you would have to download the WPA2 patch from Microsoft. <http://support.microsoft.com/kb/893357> The documentation of your Wireless devices (Wireless Router, and Wireless Computer's Card) should state the type of security that is available with your Wireless hardware. All devices MUST be set to the same security level using the same pass phrase. Therefore the security must be set according what ever is the best possible of one of the Wireless devices. I.e. even if most of your system might be capable to be configured to the max. with WPA2, but one device is only capable to be configured to max . of WEP, to whole system must be configured to WEP.

Windows takes its Encryption setting from the Wireless card's drivers. If the drivers, or the card, do not support advanced security nothing can be done about it. Check the support site of the card's vendors for the card's capacities and updated drivers. If it does not support reasonable security get a new PCMCIA card a good card that can do WPA or WPA2 is less than $20.

There is a difference between the method used for *authentication* and the method used for *encryption* of the wireless traffic once authentication has been established. If you are forced to use WEP (hardly effective these days) you should use "open" authentication (as you discovered). The following excerpt from a MS TechNet article may be of some interest: <quote: http://technet.microsoft.com/en-us/library/bb457016.aspx> The following types of authentication are available for use with 802.11 networks: * Open System * Shared Key * IEEE 802.1X * WPA or WPA2 with preshared key Open system authentication is not really authentication, because all it does is identify a wireless node using its wireless adapter hardware address. .... Shared key authentication verifies that the wireless client joining the wireless network has knowledge of a secret key. During the authentication process, the wireless client proves it has knowledge of the secret key without actually sending the secret key. For infrastructure mode, all the wireless clients and the wireless AP use the same shared key. For ad hoc mode, all the wireless clients of the ad hoc wireless network use the same shared key. .... For a home or small business that cannot do 802.1X authentication, WPA and WPA2 provide a preshared key authentication method for infrastructure mode wireless networks. The preshared key is configured on the wireless AP and each wireless client. The initial WPA or WPA2 encryption key is derived from the authentication process, which verifies that both the wireless client and the wireless AP are configured with the same preshared key. Each initial WPA or WPA2 encryption key is unique. .... The following are the recommended security configurations, in order of most to least secure: .... * For the home or small business network that does not contain a domain controller and a RADIUS server and supports WPA2, use WPA2 and preshared key authentication. * For the home or small business network that does not contain a domain controller and a RADIUS server and supports WPA, use WPA and preshared key authentication. For the home or small business network that does not contain a domain controller and a RADIUS server and does not support either WPA or WPA2, use open system authentication and WEP. However, this is not a recommended security configuration and should only be used temporarily when transitioning to a WPA or WPA2-based wireless network. </quote> The article goes on to explain why shared-key authentication in conjunction with WEP is less secure than open authentication and WEP (aside from the fact that WEP is in general very easy to defeat these days) because it is easy for a sniffer to grab the key during the authentication process. -- Lem -- MS-MVP To the moon and back with 2K words of RAM and 36K words of ROM. http://en.wikipedia.org/wiki/Apollo_Guidance_Computer http://history.nasa.gov/afj/compessay.htm
