Wireless N Nano USB adapter the TP-Link TL-WN725N allows to connect a Hubitat hub (C5/C7) to a wireless network (wi-fi) at speed of up to 150Mbps. This will let you place your hub further away from your wi-fi router but presumably in a more central position of your home/office to better cover the area with Z-Wave and Zigbee networks.
