The Logitech streaming radios are okay. I’m flummoxed why there was a problem, because knowing the G3100 wouldn’t honor IP addresses it didn’t allocate, I had reset the IOGEAR Ethernet-to-WiFi adapters (with a paperclip) to clear their original IP addresses. Then for each of them I went through the WPS process with the new router.
They ran for days without a problem, but when it hit, all of the streamers exhibited a recurring loss of connection from their adapters. Which is why I’m on the lookout for the failures returning.
