A:Answer I use a Netgear Orbi mesh network that chooses the best network for the device (5 GHZor 2.4 GHZ). The Express and 4K streaming devices only seem to go on the 2.4 GHZ network. I did notice the 32" Sharp w/ Roku TV I just bought to use in my office uses 5 GHZ. Hopefully, this is a sign of Roku making the switch and not Sharp's standards. But, for now, they seem to be using 2.4 GHZ.
