Workgroup not accesible on wireless

I have recently setup my wirelss network using a MN500.
The two computers using ethernet and cable can talk to
each other. But my laptop, using wirless connection, when
trying to access "View workgroup computers" in Windows XP
gives me the error message "Workgroup not accesible. You
might not have permission to use this network resource.
Contact the administrator of this server to find out if
you have access permission"

All computers have the same workgroup name, file sharing
is enabled, etc. Am I missing something. Please help.

I am having the same problem. However, the cabled
computer is listed under other network devices in the
Broadband Network Utility. It also says that I am
connected to the network workgroup.
