Local Switching Issues
In some instances, an error message containing 
“SSR setup failed.mac” and a multicast address 
can be ignored. (44605)
Windows VISTA Issues
Windows 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:

dows XP with Service Pack 2:

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 
Microsoft’s directions on how to change the default 
behavior of the Vista wireless client:

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 notice-
able 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 author-
ities (CA), verify that the CA’s public certificate is 
included with all of the web browsers that you sup-
port on your network.
