Mark,
Since the current version of the SmartThings Hub supports both WiFi and Ethernet connections, the best way to hook up the hub will be based on the space you are turning into your SmartThings home network. Check out this helpful resource on our Support page here -- https://support.smartthings.com/hc/en-us/articles/209963206 -- regarding the range of the Hub and the maximum-power directions for both the ZigBee and Z-wave antennas. If you have additional questions, reach out to our dedicated SmartThings team at support@smartthings.com or 1-866-813-2404 for assistance. Thank you for considering SmartThings! ~Samsung Brand Ambassador
