I can connect to a DIR-655 at 300 Mbps using Windows.  The version of the wireless manager which came on the CD i think it was 1.1 allowed me to connect.  The updates do not.  I called Tech Support and they were unable to assist me.  I tried email Tech Support I received the same information about disabling windows configuration utility.  That still did not work and I was told to call tech support again.  I suppose I should be happy that windows allows me to connect at the max speed but  I would really prefer to use the dlink utility.  Any suggestions would be greatly appreciated.
