What do you mean "the network"? Do you mean the wi-fi you told it to not connect to or something else? Because something else sounds like a secondary path. It's enumerating devices for a reason. How many of those devices are LG or an LG partner?

Wifi exists now lol, and if there are open wifi networks in the vicinity, it can use it.

Unless it is factory reset (and even then?) it presumably still has saved wifi credentials?
