Wired is always better than wireless. If wired isn’t an option, 5ghz is the best way to go. It’s unfortunate that amazon doesn’t have an Ethernet port in their dongle. It’s a downgrade from the box it replaced. I have an Ethernet port next to my TV as I’m fortunate to have Ethernet wired throughout the house. Not having an Ethernet port is a reason not to buy the dongle in my opinion. It’s too bad Dish Anywhere isn’t available on Roku.
