The Control4 USB WiFi Adapter is a USB 2.0 802.11 WiFi module that provides WiFi network access for Control4 products that do not have built-in WiFi and where an Ethernet connection may not be available. Control4 recommends that a hardwired network connection be used whenever possible. Sometimes the planned network connection may be faulty or unavailable. In those situations, C4-USBWIFI can be a useful tool to get the job done.
