Once again Flex came through with a solution. I could not get the upgrade to version 3.x to work. I could not get the radio to recognize I had paid for an upgrade. In stepped Eric, KE5DTO, with a solution. This is a new house and wired for high-speed internet access. We have 1 Gb service. There is a modem in the garage. There is not a router anywhere. Central in the house there is a little black box (literally black) that established a WiFi hotspot. It is not a router! I opened it and it uses a WiFi chip and a couple of other chips. My 6500 is directly plugged the computer. Eric found a means to get the update done without a router. I could not ask for more-- Thanks Eric.
