Windows VISTA IssuesWindows Vista clients cannot connect to “hidden” SSIDs.

In its default configuration, Windows Vista does not connect to hidden “non-broadcast” SSIDs. Microsoft has changed this behavior in both Vista and the latest Windows client update for XP (KB# 917021) as part of an effort to increase security on wireless clients. For more information, please check the following URLS on Microsoft’s website:

3Com recommends that, if you do not have direct control over the configuration of the wireless clients accessing your network, do not configure your service profiles with hidden SSIDs.

If you do have direct control over client configuration, you can change the default behavior. Here is a link to

IE 7 issues with self-signed web-portal certificates

Microsoft has introduced more strict client security in Internet Explorer 7.0 which makes the use of self-signed certificates more confusing for end-users. When the WX attempts to process a client’s web- portal login request, a screen displays this notice: “There is a problem with this website’s security certifi- cate” every time a client attempts to authenticate if the WX is using a self-signed certificate. While it is possible to choose the “Continue to this website” option, the user is discouraged from doing so for security reasons. This situation may lead to a noticeable increase in support calls from confused end-users.

3Com recommends that you do not use self-signed certificates for Web-Portal. In addition to the security issues with using an unverified certificate, the user experience is severely affected for IE 7 users. Use Veri- sign or another less expensive certificate authority to purchase a third-party verified certificate. If you are not using one of the major Internet certificate authorities (CA), verify that the CA’s public certificate is included with all of the web browsers that you support on your network.
