I have an Android phone with Syncthing app and a Windows desktop computer with Synctrayzor. The computer is connected to a modem with an ethernet cable and the phone is connected to the modem’s wifi. I’ve set it up so that when I take a photo with my phone, it’ll be synced to my desktop computer. It works great.
But today I noticed that the photos will transfer although I turned off wifi on my phone, and even turned off the modem’s wifi. I didn’t know this was possible, I thought everything’s syncing through modem’s (w)lan. Should it work like this? Have I maybe set it up incorrectly?
