I cannot connect to a wireless network if I'm connected to an ethernet network. I need to be able to connect to both different netowrks at the same time.
In some PC's there is a setting in BIOS for this however looking into Beelink BIOS there is no related setting.
Usually, it is possible to connect WIFI and Ethernet at the same time, but when connecting WIFI and Ethernet at the same time, Ethernet will be used in preference, can't your product connect to the network at the same time?
