When you enable the standard tethering on Android, can you specify/by default does it use an existing WIFI connection to transfer traffic if possible? For example, at home I might have a WIFI network named
home_WIFI, which I don't want strangers connecting to for security reasons. On the other hand, I'd like to let set up a publicly accessible access point (my Android phone) by the name of say
public_net which they can connect to. What I would then like is for my Android phone (
public_net) to route any traffic through
home_WIFI behind the scenes, rather than using the expensive/slow mobile data.
Does anyone know if Android already does this/can be made to do this? When I setup tethering, I get a tethering active notification, but am unsure whether it's defaulting to WIFI or mobile data behind the scenes...
