What is Infrastructure mode?
Infrastructure mode is a wireless network framework that has a central WLAN access point/router at the heart of the network. In infrastructure mode, wireless devices communicate with each other through an WLAN access point/router. When the Brother wireless machine is part of infrastructure mode network, it receives all print jobs via an WLAN access point/router.
The WLAN access point/router can also act as a bridge or a gateway to a wired network, and wireless devices can communicate not only with each other but also with a wired network.
