Ubidium includes Wi-Fi capability using an on-board Wi-Fi module, this Wi-Fi is separate from the 2.4 GHz used for active timing, and does not have any external antenna port. 

The Wi-Fi supports both 2.4 GHz and 5 GHz networks, and can act as both a client and access point. When operating in client mode then 5 GHz will always be preferred to prevent interference with the 2.4 GHz used for active timing. 

The Wi-Fi settings are configured through the Network Settings menu.
