I have a question maybe you can help me with. I share my neighbor's wifi by means of a repeater setup up as an extended network with a separate SSID and password. I thought this would hide my Google home seeing it is connected to my extender and not directly to his router. Apparently, I was wrong because when I directly connected to his router via my computer and opened an incognito window in chrome, I was able to see and cast to my Google home under the "cast option.
Any suggestions on how to fix this so they cannot see my google home??
