So what you're running into is only caused by (temporarely) connecting your SBC with both network interfaces to the same AP/router that is most probably configured as a bridge between wired/wireless using same IP address range. As soon as your AP doesn't remember to connect to your WiFi MAC address through the Ethernet interface the problem is solved. I also have a WiFi printer that I need to. And possible force all of the iTunes traffic to the WiFi adapter. I was hoping I could have both adapters active at the same time. But I use iTunes Home Sharing and that requires my PC to be on the same WiFi network as my other devices. The whole 'problem' boils down to legacy sun8i kernel behaviour, MAC addresses, ARP tables/caches, routing settings on your AP when you first connect your SBC with both Ethernet and WiFi to the same network (your AP/router is involved here too). Id like to connect my PC to the Internet via the Ethernet adapter. Iam assuming the answer is an obvious yes but just thought id ask anyhow. Unplug Ethernet cable from your SBC (this is totally unrelated to OPi Zero, I emphasize on this since a few morons on the net constantly claim OPi Zero would have non working Wi-Fi) Can i use ethernet and wifi at the same time Hi guys. That's simply not true. In case you already established a Wi-Fi connection to your AP (using nmtui or nmcli) then simply do the following:

Mac ethernet and wifi same time
