Trying to deal with the frustration of useless wifi operation of my Maestro, I tried a different router. The router booted up normally and Ethernet and wifi was present. I then applied external dc to the Maestro and began to boot up. The maestro detected the wifi signal and I successfully signed in to the router. The maestro detected the Flex 6500 and then I selected the software version. The maestro screen went blank for some time. Then, the basic GUI for both slice receivers begin to appear. At that point, the Maestro freezes and eventually, a windows 10 style error message appears saying that Maestro is not responding. Removing dc power is the only way I have been able to clear the screen. I have repeated this several times and I replaced my test router with my Asus RT-AC87R and the same results are observed. I have tried using Ethernet cable, wifi, and "Both" connections with the same results.
