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.
