Wonder why RT rigged it up that way! Other 2.4 only things aren't that way. This has caused headaches for lots of folks. I may try to fire up my old router that can separate the 2.4 and 5G SSIDs and see how goes it.You could always start and run the grill using the app on your phone when connected to a 5GHz wifi, it's the initial connection the grill needs must and will always be the 2.4GHz.
