It has to "join" the network like any other wifi device. That's how wireless Ethernet works. I haven't seen any detailed info on how koob's wifi syncing works but I suspect once the kobo obtains its IP, it sends out a broadcast Ethernet message for the desktop app to pick up. If your wireless network is separate from the wired, it's possible the desktop app won't be able to see the kobo's broadcast message.
