Wanting to add to my IAP-104 cluster, I discovered that the IAP-104s are no longer available. So my vendor sent me IAP-204s. I unpacked the first device and connected it to my network, but my virtual controller can't see it. I talked to my vendor, who said I'd need to upgrade the firmware on my IAP-104s. But when I click on the "check for new version" botton, a message comes back saying there is no new version. But my version is 6.1.3.1-3.0.0.1_33617, and the vendor said I needed at least 4.1.1.0. Is updated firmware available for my devices? If so, how do I get it? If not, is there any way to get the IAP-204 devices talking to my IAP-104 cluster, or am I out of luck?
